1: Getting Started

Now that you have your mangOH™ Red, it’s time to start using it.

Important: Use this guide only if you are using a native Linux development system (Ubuntu

is recommended).

This guide includes instructions for native Linux® development machines using CLI (Command Line Interpreter).

This Getting Started guide takes you from assembling your mangOH Red and setting up your computer for mangOH development, through to installing and running applications and sending data to the IoT Cloud via AirVantage, Sierra Wireless’ cloudbased services platform for over-the-air (OTA) device management.

To get started with Windows systems, or for other mangOH Red resources (guides, tutorials, etc.), visit mangoh.io/mangoh-red-resources.

1.1 Minimum System Requirements

Make sure your computer meets the minimum suggested requirements for application development with the mangOH Red.

Table 1-1: Minimum System Requirements

Linux

O/S Ubuntu 16.04

CPU Dual core @ 2.6 GHz RAM 4GB HDD 10 GB free space

Note: The instructions in this guide have been tested on Ubuntu 16.04. If you choose to use a different distribution (e.g. Debian, Fedora, etc.), you may need to adjust commands, set permissions, etc. If you need assistance, please check out the forum at forum.mangoh.io.

1.2 Quick Start Contents

Important: Carefully follow the procedures as described—each section builds on earlier

procedures and results. If you skip steps or use alternate methods, you may have difficulty completing the tutorial.

2: Before You Begin

Before you begin, here are a few items that you might find helpful:

• Some terminology:

· "CF3"—The mangOH Red supports CF3 (Common Form Factor) embedded

modules, such as the WP8548 and HL8548. Throughout this tutorial, "CF3" refers to the module that comes with your mangOH Red kit.

· "Dev(elopment) machine"— Your Linux computer

· "Target"—The CF3 module in your mangOH Red.

• Some symbols:

· ’$’, ’#’— Command prompts.

· ’$’—Command prompt when you are logged in to a device as a regular

user.

· ’#’—Command prompt when you are logged in as the ’root’ user.

Note: In the examples in this document, you will be logged in as a regular user on your dev machine (command prompt will be ’$’), and logged in as the root user on the target (command prompt will be ’#’).

· ’~’, "$HOME"—Your ’home directory’ on your dev machine.

• Command examples— Many steps in this guide require you to enter commands in

a terminal window. These commands are shown like this:

$ ping 192.168.2.2 # cd ~

Note: You can copy commands from this guide and paste them in to your terminal window to save time and avoid typing errors. Do not include the command prompt when you copy/enter commands. (In the first example above, you would enter "ping

192.168.2.2", not "$ ping 192.168.2.2".)

• CF3 module default credentials and IP address (used to connect to the target from the dev machine):

· USB ECM IP address—192.168.2.2

· User name—root

· Password—<none>

• Terminal window tips:

· Shortcut to open a terminal window (on the default Unity desktop used in

Ubuntu Linux)— Ctrl+Alt+T

· Cancel command to break out of a running process— Ctrl+C

· minicom exit command— Ctrl+A, then press X

The triangle on the label matches the position of the triangle on the socket.

The triangle on the label matches the position of the circle on the cover.

3.2 Hardware Setup

To set up the mangOH Red board:

1. Insert the CF3 module— Hold the module above the socket and line up the triangles on the module and socket. The module will drop straight into the socket. (Position matters!)

2. Hold the module cover over the module and line up the circle on the cover with the triangle on the label, then press the cover (on the edges) into place.

Rev 2 8/23/17 10 41110481

3. Remove the protective film from the dipswitches:

Remove this film

Note the location of the notched corner.

Inserted in bottom part of slot

4. Make sure the dipswitches are set as follows:

· ON—1,3,8

· OFF—2,4,5,6,7

5. Insert a micro-SIM in the slot on the bottom side of the mangOH Red. You can

use the Sierra Wireless micro-SIM that is included in the kit, or another micro-SIM that has been activated by a mobile network provider.

Note: If you do not have an activated micro-SIM, you can still continue with the tutorial, but will not be able to complete the following sections: Co nnect To Mobile Networks on

page 29 and Connect to the IoT Cloud on page 34.

6. Attach the main antenna and (for LTE CF3 modules) the diversity antenna.

Note: The main antenna is required if you want to connect the mangOH Red to a mobile network in Connect To Mobile Networks on page 29.

Tip: If you have trouble connecting an antenna, make sure it is positioned directly on the

connector and push straight down. The antenna will not connect at an angl e.

Note: The mangOH Red has two USB connectors. CF3 USB is used for SSH connections, AT commands, and firmware downloads, and CONSOLE_USB is used for serial USB connections for debugging and to access the module’s console.

7. Move the power select jumper to select the CF3 USB connector—in this guide, power is supplied from the dev machine’s USB port to this connector.

Rev 2 8/23/17 12 41110481

8. Use a micro-USB cable to connect the CONSOLE USB connector to a USB port on your dev machine.

9. Open a terminal window on the dev machine— this window will be used to display the target’s console messages (kernel messages, warnings, etc.).

Note: Depending on your desktop, a terminal window may be opened using a keyboard shortcut (e.g. Ctrl+Alt+T for the Ubuntu Unity desktop), or an icon or menu item .

10. Connect to the target’s Linux console as follows:

a. In the terminal window, enter the following command to install the minicom

application on your dev machine (if it is not already there), and follow any prompts that may appear:

$ sudo apt-get install minicom

Note: ’sudo’ tells the dev machine to run the command as the ’superuser’. Each time you use sudo, you must enter your dev machine’s password to continue.

b. Connect to the target’s Linux console via the USB serial port (which

enumerated when you connected the CONSOLE USB connector to the dev machine):

$ minicom -D /dev/ttyUSB0

A welcome message appears, and the window will show console messages when the mangOH Red powers on in the next step.

Rev 2 8/23/17 13 41110481

mangOH Red Getting Started

CF3 USB connector (bottom side of board)

11. Power up the mangOH Red:

Note: The USB serial port enumerates as ttyUSB0 because you connected CONSOLE USB to the host before connecting CF3 USB to the host (which you will do later). However, if you connected CF3 USB first, it would enumerate ttyUSB0, ttyUSB1, and ttyUSB2. Then when CONSOLE USB is connected, it will enumerate as ttyUSB3.

Note: You can exit minicom at any time—the purpose of showing it here is to demonstrate how to display console messages for debugging purposes. To exit minicom, press Ctrl+A, then press X. When prompted, select Yes to leave minicom.

Note: Through the rest of this guide, examples use terminal windows connected via ssh, but a console connection could also be used. However, only one console conn ection can be opened at any time since it locks the USB serial port.

a. Use a micro-USB cable to connect the CF3 USB connector to a USB port on

the dev machine.

Rev 2 8/23/17 14 41110481

When the mangOH Red is powered, the Power LED turns solid green and

Power LED

Console messages describing module boot-up process

startup messages will appear in the terminal window that you connected to the target’s console in Step 10.

Note: For future reference, the mangOH Red’ s power supply (USB port on your dev machine, or an AC adapter) connects to the board via either USB connector—

CF3 USB or CONSOLE USB (depending on the jumper position on the power header). If an AC adapter is connected to CF3 USB, SSH/AT connections are not possible; if it is connected to CONSOLE USB, serial USB connections are not possible.

12. On the dev machine, open another terminal window.

13. Make sure the modemmanager package is removed from your system (this

package causes problems with mangOH Red if it is not removed):

$ sudo apt-get remove modemmanager

14. Wait 10-15 seconds for the mangOH Red to enumerate.

15. Test the CF3_USB connection:

$ ping 192.168.2.2

Rev 2 8/23/17 15 41110481

You should receive ping responses. Press Ctrl+C to cancel the ping request and return to the command prompt.

Rev 2 8/23/17 16 41110481

4: Prepare Your Linux Dev Machine For Legato Development

In this chapter, you will prepare your dev machine for Legato application development by setting up the development environment with required applications and packages.

Important: To install and use the development environment, your dev machine must meet

the requirements in Table 1-1 on page 6.

4.1 Prepare Dev Machine For Application Development

After preparing your mangOH Red hardware in Set Up Your mangOH Red Hardware

on page 9, you can prepare your dev machine for application development:

Important: Download, installation and use of Legato Application Framework and Platform

Services is subject to the Legato License and Open Source Licenses. (Note: These links automatically download the licenses as PDF files.)

4.2 Build and Install the Development Environment

In this section you will build and install the environment to develop applications for the CF3 module used in your mangOH Red. The environment includes:

• Legato toolchain— Tools and libraries used to build the Legato Platform for your CF3 module. The Legato toolchain is module-specific; you must make sure you install the toolchain designed for your module.

• mangOH Red platform— Drivers for on-board components, and a basic device-to-cloud application.

To build and install the development environment on your dev machine:

1. Open a terminal window.

2. Install packages required for the development environment:

a. Display your Ubuntu version:

$ lsb_release -d

Note: If the version is less than 16.04, upgrade your operating system to 16.04 or higher, then continue with these instructions.

Rev 2 8/23/17 17 41110481

mangOH Red Getting Started

When prompted to continue, type Y and press Enter.

Installation messages Actual messages displayed will vary depending on which packages are already installed

The command worked (value = 0). Any other value (2, 100, etc.) would

mean the command failed.

3. Check whether your dev machine is 32-bit or 64-bit:

4. Install several packages that are required for the Legato Platform and the

$ uname -m

The dev machine’s hardware type appears —e.g. "x86_64" is a 64-bit system.

mangOH Red platform— enter the following command and follow any prompts that appear:

$ sudo apt-get install build-essential openjdk-8-jre \

libwebkitgtk-1.0-0 python python-jinja2 cmake \ git subversion libsdl-dev diffstat texinfo gawk \ chrpath wget cpio vim zsh bash ninja-build screen \ sshpass bc python-git unzip libxml2-utils gcovr \ libcurl4-gnutls-dev zlib1g-dev libbz2-dev \ bsdiff libssl-dev zip autoconf automake

Note: The ’\’ at the ends of the lines tells the system that the command continues on the next line. When you run this command (and any others in this guide that use the ’\’), you can copy and paste the full command (including ’\’ characters) in your terminal window. If you type the command manually all on one line, do not type the ’\’ characters.

5. As shown in the previous step, the output you see when you run some commands may be different from the examples shown. To check if a command succeeded or failed, enter the following command:

$ echo $?

Rev 2 8/23/17 18 41110481

If the value returned is ’0’, the command succeeded. If it is any other value, the

Click Download on the latest (newest) 32-bit or 64-bit toolchain link

command failed.

6. If your dev machine is 64-bit, install additional dependencies:

$ sudo apt-get install lib32z1 lib32ncurses5

7. Build the Legato toolchain (SDK):

a. If you have previously installed Legato toolchains, make sure you do not have

any old toolchain files ("poky*.sh") in your Downloads directory (e.g. ~/Downloads), and remove any changes that may have been made to your .bashrc file:

i. Go to your Downloads directory:

$ cd ~/Downloads

ii. Either move or delete any old toolchain files:

Delete files:

$ rm poky*

Move files:

$ mkdir old_toolchains $ mv poky* old_toolchains

iii. Edit your ~/.bashrc file, comment out any items at the bottom of the file

that begin with "LEGATO", and save and close the file.

b. Go to http://source.sierrawireless.com/resources/legato/downloads and click

the latest Legato (32-bit or 64-bit) toolchain download link (the link is to a .sh file).

Note: You must register on the Source for an account before you can download files.

c. Click Download.

d. If prompted, save the file to your Downloads folder. (e.g. ~/Downloads)

Rev 2 8/23/17 19 41110481

mangOH Red Getting Started

e. In the terminal window, open the folder and run the file.

(In the command below, replace <file_name> with the actual file name. e.g. If the file name is "poky-swi-ext-sample-1.7.3.sh", the command would be "bash poky-swi-ext-sample-1.7.3.sh"):

$ cd ~/Downloads $ bash <file_name>

f. When prompted to enter a target directory for the SDK, press Enter to accept

the default (/opt/swi/y17-ext).

g. When prompted to install or (possibly) replace the SDK, type ’Y’ and press

Enter.

When finished, installing, the message "SDK has been successfully set up and is ready to be used." will appear.

h. Configure the toolchain to make it available for use in generating the

mangOH Red platform and the kernel modules that it references:

$ export PATH=$PATH:/opt/swi/y17-ext/sysroots/\

x86_64-pokysdk-linux/usr/bin/\ arm-poky-linux-gnueabi

$ cd /opt/swi/y17-ext/sysroots/\

armv7a-vfp-neon-poky-linux-gnueabi/usr/\

src/kernel $ sudo chown -R $USER . $ ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- \

make scripts $ sudo chown -R root .

Rev 2 8/23/17 20 41110481

8. Install the repo application, which will be used to clone the Legato file repository:

Platform downloads to ~/mangOH_work.

If you don’t put a name here, it downloads to mangOH (the name of the directory on github).

Returns to command prompt with no

error messages.

$ sudo apt-get install repo

Note: This may take a few minutes to run.

9. If the install in Step 8 failed because phablet-tools was previously installed:

a. Enter the following command:

$ sudo apt-get remove --purge phablet-tools && \

apt-get install repo

b. Go back to Step 8.

10. If you have not used git or git-repo to clone a project before, identify yourself as

follows:

$ git config --global user.email "youremail@example.com" $ git config --global user.name "your.name"

11. Download the mangOH platform files into a working directory—enter the following command and either replace <mangOH_work_directory> with a new directory name (e.g. "mangOH_work"), or remove it (to use the default directory name "mangOH").

$ cd ~ $ git clone --recursive https://github.com/mangOH/\

mangOH <mangOH_work_directory>

Note: <mangOH_work_directory> is optional—if not used, a working directory is created with the same name as the repository (in this case, "mangOH").

Rev 2 8/23/17 21 41110481

mangOH Red Getting Started

12. Add an environment variable (shortcut) for the mangoh work directory:

Now that the Legato development environment is installed, you can Prepare Your

mangOH Red For Development on page 23.

a. Edit your ~/.bashrc file (the startup script that runs when you open a terminal

window) and add the following line at the end of the file:

export MANGOH_ROOT=~/mangOH_work

Note: . If you downloaded into a different directory name in Step 11, replace "mangOH_work" with that name in the above export statement:

b. Save and close the file.

c. Run the script to set the new environment variable for your current window:

$ . ~/.bashrc

Important: Make sure you include the ’.’ (period) at the beginning of the

command. This command runs the script in the open terminal window; you will not have to run it in new windows.

Rev 2 8/23/17 22 41110481

5: Prepare Your mangOH Red For Development

Most recent release

In this chapter, you will update the CF3 module on your mangOH Red with the basic mangOH Red platform (application suite).

5.1 Build and Install Legato Platform and

mangOH Red Platform on Target

Now that your dev machine has its development environment set up, you can build and install the Legato Platform and mangOH Red Platform application suites onto your target (the CF3 module in your mangOH Red):

1. Get the Legato Application Framework (AF):

a. Go to http://legato.io/legato-docs/latest/aboutReleaseInfo.html to get the

version number of the most recent release.

Rev 2 8/23/17 23 41110481

b. Download the framework files into a working directory (for example,

"legato_framework")— Replace the release number in the ’repo’ command with the most recent release (this example downloads version 17.07.1):

i. Create a working directory below your home directory to hold the

framework files (for example, "legato_framework"):

$ mkdir ~/legato_framework

Note: Through the rest of this guide, "legato_framework" is assumed to be the file you created. If you used a different name, make sure to use that name in any commands that refer to legato_framework.

ii. Download the framework files into the work directory:

$ cd ~/legato_framework $ repo init -u git://github.com/legatoproject/\

manifest -m legato/releases/17.07.1.xml

$ repo sync

mangOH Red Getting Started

IMEI

Ignore these toolchain warnings.

Note: This may take several minutes to run.

2. In a terminal window, build and install the Legato AF:

$ cd legato $ make clean && make wp85 && source bin/configlegatoenv

Rev 2 8/23/17 24 41110481

3. Go to the mangoh work directory and build the platform:

$ cd $MANGOH_ROOT $ make red_wp85

Note: This may take several minutes to run.

Note: In the command "make wp85", ’wp85’ indicates the target type on which the applications will run. If a different module type is used, the make command must be modified to indicate the correct type. For example, if the CF3 module is a WP7602, the target must be changed from "wp85" to "wp76". This applies to all make commands described in this guide.

4. Verify that the update file mangOH_Red.wp85.update was created:

$ ls -al *.update

6: Connect To Mobile Networks

Note the location of the notched corner.

Inserted in bottom part of slot

In this chapter, you will learn how to connect the mangOH Red to a mobile network. When the mangOH_Red has a data connection, you can transmit data, including onboard sensor readings, to the IoT cloud.

6.1 Connect To a Mobile Network

To connect to a mobile network, you must have an activated micro-SIM in the mangOH Red.

1. If you do not have a micro-SIM in the mangOH Red, insert one before continuing:

a. Disconnect the power from the mangOH Red (remove the jumper from the

power header, or unplug the micro-USB cable that is providing power).

b. Insert a micro-SIM in the slot on the bottom side of the mangOH Red. You

can use the Sierra Wireless micro-SIM that is included in the kit, or another micro-SIM that has been activated by a mobile network provider.

c. Reconnect the power (plug in the micro-USB cable or insert the jumper on the

power header on the same pins it was removed from in step a. The Power LED will light immediately.

Note: You must disconnect the power before sw itching SIMs so the mangOH_Red can detect the SIM while powering on.

2. Connect to the target’s console:

a. On the dev machine, open a terminal window.

b. Connect to the target:

$ ssh root@192.168.2.2

5. If the:

· Power is OFF—Turn on the radio and then repeat Step 4:

# cm radio on

· Power is ON and Status is ’searching’— Wait 10–15 seconds while the radio searches for a network to register on, then repeat Step 4.

· Power is ON and Status is Registered— Continue to Step 6.

Rev 2 8/23/17 30 41110481

6. Check the connection status:

Example response when Not connected, APN is set

Example response when Not connected, no APN

Example response when Connected

# cm data

a. If "Connected" is:

· "no", and APN has a value— The mangOH Red is ready to connect to the

network. Go to Step 7.

· "no", and APN is blank — You must set the APN. Continue to the next step

(step b).

· "yes"—The mangOH Red is connected to the network. Go to Step 8.

b. If you need to set the APN, replace "<your apn>" with the actual APN in the

following command:

# cm data apn <your_apn>

Note: The APN for the Sierra Wireless SIM is internet.sierrawireless.com.

Note: If your mobile network operator uses different APNs for 3G and LTE, make sure to use the APN for the correct network based on your CF3 module type. For example, the WP8548 is a 3G-only module that does not support LTE—the APN for the network operator’s 3G network should be used.

Rev 2 8/23/17 31 41110481

mangOH Red Getting Started

If you do not know the APN for your SIM:

i. Get your Home Network Operator name:

# cm sim info

ii. Search the Internet for the APN for your Home Network Operator (for

example, search for "I TIM APN").

iii. Set the APN as described above.

c. Check the connection status again to make sure you set the APN correctly:

# cm data

7. Set up a data connection to the mobile network:

# cm data connect

Several status messages will appear—if the connection succeeds, all the messages indicate "ok".

8. Test the data connection:

a. When the command prompt reappears, verify that the connection is

working—’ping’ a URL that you know is working (e.g. mangoh.io, google.com, etc.).

# ping mangoh.io

When ping responses (e.g. "64 bytes from 35.164...") appear, the connection is working. (Responses may take 10–15 seconds to being appearing.)

Rev 2 8/23/17 32 41110481

b. Stop the ping command when responses begin to appear—Press Ctrl+C to

return to the command prompt.

Note: If no responses appear within 30 seconds, press Ctrl+C , make sure the antenna is connected, and go back to Step 4 and try again. If you still cannot get a response, power cycle the mangOH_Red and start the procedure again.

9. Now that you know how to start a data connection, you will be able to transmit data to the IoT cloud. (In the next section, you will set up your free account on the Sierra Wireless AirVantage IoT Acceleration Platform.)

For now, enter the disconnect command to close the data connection while you set up your AirVantage account:

# cm data connect -1

Now that you know how to start (open) and stop (close) a data connection, you are ready to Connect to the IoT Cloud on page 34 and begin sending data to the ’cloud’.

Rev 2 8/23/17 33 41110481

7: Connect to the IoT Cloud

In this section, you will register your device with Sierra Wireless’ AirVantage IoT Acceleration platform (a cloud-based service to collect data from your device), and begin submitting your mangOH Red’s on-board sensor data.

7.1 Register and connect to AirVantage

Your mangOH Red kit includes a free account on the AirVantage IoT Acceleration Platform for your CF3 module. This platform provides Sierra Wireless’ cloud-based services for over-the-air (OTA) device management and application enablement. These services provide the infrastructure for you to build, connect, and operate your IoT applications in a single platform.

Note: You can register up to five devices (CF3 modules and other supported devices) on your free account.

Rev 2 8/23/17 40 41110481

To begin developing simple applications or modifying existing applications, work through the examples in Develop and Test applications on page 42.

Rev 2 8/23/17 41 41110481

A: Develop and Test applications

In this section, you will learn how to develop applications in the Legato development environment, install them onto your mangOH Red, and test that they run.

Legato provides two interfaces for developing applications:

• CLI—Command Line Interpreter in a terminal window.

• Developer Studio—A GUI (Graphical User Interface) development environment.

This section describes development using CLI.

Note: You will be updating application source code in this section. Use whichever editor you prefer—these instructions do not refer to a specific editor.

Tip: This tutorial touches on the basics of using the Legato development environment. After

completing the examples in this chapter, see http://legato.io/legato-docs/latest/mangOH_devel-

opers.html for detailed references, forums, etc.

A.1 Develop using the CLI—Command Line Interpreter

A.1.1 Configure the Dev Machine’s Terminal Windows for Development

Note: If you installed Legato to a subdirectory of your home directory using a different name than ’legato’, replace "~/legato" with "~/<yourDirectory>" in the commands in this secti on.

To use the CLI in a terminal window to compile and build applications, you must configure the window to work with Legato tools.

The easiest way to do this is to define a short ’alias’ in your ~/.bashrc file (the startup script that runs each time you open a new terminal window) that you can use to run the required commands (instead of entering the commands manually every time):

To modify your .bashrc (you only need to do this once on your dev machine):

1. Open a terminal window.

2. Edit your ~/.bashrc file and add the following lines at the end of the file:

alias cfglegato=\ "pushd . && cd ~/legato_framework/legato && source ./bin/configlegatoenv ; popd"

3. Save and close the file.

4. Run the script to set the new environment variable for your current window:

$ . ~/.bashrc

Rev 2 8/23/17 42 41110481

Important: Make sure you include the ’.’ (period) at the beginning of the command. This

Power is OFF

command runs the script in the open terminal window; you will not have to run it in new windows.

Now each time you open a new terminal window, you can:

1. Enter the alias (cfglegato) to configure the window:

$ cfglegato

Note: One of the things the command does is check to see which toolchains you have on your development machine and warns you about any that are missing. Since you have loaded only the wp85 toolchain, warnings appear about the others. You can ignore these messages.

2. Confirm that the environment was set correctly:

$ echo $LEGATO_ROOT

If a directory path appears, the command worked. If no value was returned, there was a problem with the command— make sure that you entered the alias correctly, using the actual directory name that you used to install Legato.

Note: You can also use the command "~/legato_framework/legato/bin/legs" to configure the terminal, but this starts a new shell session—your command history and any environment variables you have set will be lost.

A.1.2 Update an Installed Application

As you saw when you set up your AirVantage account, one of the mangOH platform applications loaded on your device in Build and Install Legato Platform and mangOH

Red Platform on Target on page 23 was redSensorToCloud. This application reports

sensor readings to the cloud (e.g. AirVantage) every two minutes.

In this section you will increase the reporting frequency of the redSensorToCloud application and install the new version on the mangOH Red.

To update redSensorToCloud:

1. On the dev machine, open a new terminal window.

Rev 2 8/23/17 43 41110481

mangOH Red Getting Started

2. Configure the window for development— enter the following command (that you

3. Go to the folder containing the application’s source code:

4. The source code components for this application are in two sub-folders—

5. Open and edit the source code (avPublisher.c) with your preferred editor—two

previously set up in Configure the Dev Machine’s Terminal Windows for Devel-

opment on page 42):

$ cfglegato

$ cd $MANGOH_ROOT/apps/RedSensorToCloud

avPublisherComponent and sensorsComponent. The code that controls the

publishing frequency is in avPublisherComponent—go to that folder:

$ cd avPublisherComponent

values must be updated to adjust the reporting frequency:

a. Search for the variable declaration for MaxIntervalBetweenPublish.

static const int MaxIntervalBetweenPublish (120)

b. Change the interval value to 30— This increases the reporting frequency to at

least once every 30 seconds from once every 120 seconds.

c. Search for the variable declaration for TimeToStale.

static const int TimeToStale (60)

d. Change the stale value to 30— This decreases the length of time a sensor

reading is considered to be ’current’ before a new sensor reading must be taken.

e. Save your changes and exit the editor.

At this point, you have modified the redSensorToCloud application’s source code. Now you have to build (compile) it.

This application was created as part of the mangOH Red platform; to rebuild the application, you will rebuild the whole system (Legato Platform and mangOH Red platform). This method is suggested when applications may interact with each other. If only one application is rebuilt, it may not work properly with other applications that it depends on (or that depend on it).

To rebuild the Legato Platform and mangOH Red platform, including redSensorToCloud with your changes, and install it onto your mangOH Red:

6. Build and install the mangOH Red platform:

$ cd $MANGOH_ROOT $ make red_wp85

Rev 2 8/23/17 44 41110481

Note: This may take several minutes to run.

Note: This ’make’ command uses the Makefile in $LEGATO_ROOT to build the entire system.

7. Verify that the update file mangOH_Red.wp85.update was created:

$ ls -al *.update

8. Make sure the mangOH board is powered on and is connected to your dev machine—the board is connected if you receive ping responses:

$ ping 192.168.2.2

Press Ctrl+C to return to the command prompt.

9. Install the Project mangOH applications on your mangOH board:

$ instsys mangOH_Red.wp85.update 192.168.2.2

If the applications install successfully, the last message shown will be "SUCCESS Done".

10. After the installation is done, open a terminal window and connect to the mangOH Red:

$ ssh root@192.168.2.2

Rev 2 8/23/17 45 41110481

mangOH Red Getting Started

2 minutes interval

30 seconds interval

11. By default, redSensorToCloud is installed but not started. Start the application to send data to AirVantage:

# app start redSensorToCloud

Note: redSensorToCloud automatically opens a data connection, so you do not need to use "cm data connect".

In your AirVantage account, you will start to see sensor reports appearing on your new schedule—on the Timeline screen you can compare the timestamp intervals for new reports compared to reports received before you made your changes.

12. When you’re ready to stop sending data:

# app stop redSensorToCloud

Note: redSensorToCloud automatically closes the data connection, so you do not need to use "cm data connect -1".

Rev 2 8/23/17 46 41110481

A.1.3 Update and Install a New Application

When you installed Legato, sample application files were also stored. In this section, you will build and then install the "hello world" application on the target.

Build (compile) an application on the dev machine and install it on the target:

1. On the dev machine, open a new terminal window.

2. Set up the window for CLI development as described in Configure the Dev

Machine’s Terminal Windows for Development on page 42.

3. Go to the sample application directory for Hello World:

$ cd $LEGATO_ROOT/apps/sample/helloWorld

4. Compile the application.

$ make wp85

Note: This ’make’ command uses the Makefile in the current directory to build onl y the sample application. It does not build the entire system like the ’make’ command in Update

an Installed Application on page 43.

5. Verify that the update file helloWorld.wp85.update was created:

$ ls -al

6. Install the application on the target:

$ app install helloWorld.wp85.update 192.168.2.2

Note: This application will remain on the target until you either specifically remove it, or until the next time you reinstall the system on the target.

1. Set up a window to show the application’s output (the "Hello World" application writes to a log file) as follows:

a. Open a new terminal window (referred to as LOG_TERM in this procedure).

Rev 2 8/23/17 47 41110481

mangOH Red Getting Started

Hello World application

2. Run the application:

b. Connect to the target:

$ ssh root@192.168.2.2

c. Watch the log file and show when a message from "hello world" appears:

# logread -f | grep "Hello"

Note: Nothing will appear to happen until you run the Hello World application in the next step. Leave this command running until after you see the Hello World output, then you can press Ctrl+C to cancel it and return to the command prompt.

a. Open a terminal window to run the application (referred to as APP_TERM in

this procedure).

b. Connect to the target:

$ ssh root@192.168.2.2

c. Check that the application is installed:

# app status

The "hello world" application should appear in the list with a status of ’Running’. The application was built to run automatically; when you write your own applications, you can make them install without running, if you prefer.

d. Stop the application (so you can restart it and see the output):

# app stop helloWorld

Rev 2 8/23/17 48 41110481

e. Run the application and see that it outputs a "Hello, world." message to the

LOG_TERM terminal window:

# app start helloWorld

f. (Optional) If you want to see information about the application, enter the

following command:

# app info helloWorld

g. In the LOG_TERM terminal window, press Ctrl+C to return to the command

prompt.

You have now successfully compiled a working application, and installed, stopped, and run it on the module.

on page 23 process, you downloaded and installed the latest version of the Legato

Application Framework (AF).

When new versions of the framework are released, you can install them on your dev machine using the procedure below.

B.1 Update the Legato AF on Your Dev Machine

To update the Legato AF on your dev machine:

1. Open a terminal window.

2. Configure your environment for development:

$ cfglegato

3. Check the version of the Legato AF that is currently installed:

$ cd $LEGATO_ROOT/.. $ ls -al .repo

The installed version is indicated in the manifest.xml link.

4. Go to http://legato.io/legato-docs/latest/aboutReleaseInfo.html to get the version number of the most recent release.

Rev 2 8/23/17 50 41110481

5. If your release is older (lower version number) than the most recent release:

Most recent release

a. Download the framework files into your working directory (for example,

"legato_framework")— Replace the release number in the ’repo’ command with the most recent release (this example downloads version 17.07.1):

i. Optionally, rename your existing legato folder so that you can restore the

current framework if necessary at a later point (replace <version> with your current Legato AF version in the following command):

$ mv legato legato_<version>

ii. Download the framework files into the work directory:

C: Tips

C.1 Finding your SIM’s APN

Your SIM provider should give you the APN that you use to connect to their network. If you don’t have the APN, you should be able to find it online.

Common APNs:

· Rogers Wireless—"internet.com"

· Others—Search the Internet for "<provider> APN". For example, "Rogers

Wireless APN"

C.2 Using the Linux Terminal program

Ubuntu includes a terminal emulator, which is labeled as "Terminal" in the desktop environment. The emulator allows you to execute command-line programs that interact with the Legato framework tools on your dev machine and the CF3 module in the mangOH Red.

For this tutorial, here are some useful tips:

• Open a terminal window. For example, in the Unity desktop shell used by default on Ubuntu Linux, do this using either of these methods:

· Click the Search icon and type "terminal", then run the application that is

listed.

· Press Ctrl+Alt+T

• Open a new tab in a window—Press Ctrl+Shift+T

• Change a tab name in a window—Right-click in the tab and select Set Title.

• Copy text from a window— Highlight the text and press Ctrl+Insert.

• Paste text into a window — Press Shift+Insert.

• For in-depth detail, refer to https://help.ubuntu.com/community/UsingTheTer-
