2. OVERVIEW

This chapter provides guidelines for using AT command line interface to design, configure and provision WL865E4-P module in a wireless network using serial commands.

2.1. AT Commands

Telit wireless module family can be controlled via the serial interface using the standard AT commands.

2.2. Command Definition

This document uses the following syntactical definitions:

• Color text indicates cross-reference, hyperlinks to supplemental information

• Command notation indicates commands, sub commands, or command elements

Following table describes the text conventions used in this manual for software procedures that are explained using the AT command line interface.

Convention Type

Description

[ ] Square brackets

Name enclosed in square brackets are optional parameters. Square brackets themselves do not appear in the command line.

<CR> Carriage return

It is the command line and result code terminator character. The ASCII equivalent decimal value of <CR> is 13.

<LF> Line Feed

It is the character recognized as line feed character. The ASCII equivalent decimal value of <LF> is 10. The line feed character is output after carriage return character if verbose result codes are used (ATV1 option used) otherwise, if numeric format result codes are used (ATV0 option used) it will not appear in the result codes.

<CR><LF> Carriage return Line feed

Each command is terminated by <CR><LF>.

< > Angle brackets

Name enclosed in angle brackets are optional parameters. Angle brackets themselves do not appear in the command line.

= Equal sign

Separates the variable from explanatory text and is entered as part of the command.

PROCESSID = <CID>

. Dot (period)

Allows the repetition of the element that immediately follows it multiple times. Do not enter as part of the command.

. AA:NN can be expanded to 1:01 1:02 1:03.

A.B.C.D IP address

IPv4-style address.

2.3. AT Command Syntax

Following table describes the syntax rules followed by Telit implementation used in this manual for software procedures that are explained using the AT command line interface.

Convention Type

Description

command syntax monospaced font

This monospaced font represents command strings entered on a command line and sample source code.

AT XXXX

Proportional font description

Gives specific details about a parameter. <Data> DATA.

UPPERCASE Variable parameter

Indicates user input. Enter a value according to the descriptions that follow. Each uppercased token expands into one or more other token.

lowercase Line Feed

Indicates keywords. Enter values exactly as shown in the command description.

M/O

Gives the condition of the parameter as mandatory or optional.

Table 2: AT Command Syntax

2.4. Command Lines

A command line is made up of three elements: the prefix, the body and the termination character. The command line prefix consists of the characters “AT” or “at”, followed by “+” or “#” or without “+/#”. Most commands are prefixed with “AT+”.

To repeat the execution of the previous command line, the characters “A/” or “a/” or AT#/ or at#/ is used.

The termination character may be selected by a user option, the default being <CR>. The basic structures of the command line are:

• AT+CMD<CR> where AT+ is the command line prefix, YLC is the body of a basic command. <CR> is the command line terminator character AT+YLC=0<CR> where 0 is a sub parameter

• AT+CMD? <CR> This is a Read command for checking current sub parameter values.

WL865E4-P AT Command Reference Guide

80613ST10987A Rev. 1.4.27 Page 25 of 299 2021-01-17

The set of proprietary AT commands differentiates from the standard one because

the name of each of them begins with either “@”, “#”, “$” or “*”. Proprietary AT

commands follow the same syntax rules as extended commands.

Following are the AT commands the does not have prefixes in Responses: AT+CGMI, AT#SWPKGV, AT+CGMR, AT+CGMM, ATIn and ATI. Following are the AT commands the does not have prefixes “AT+” in Command: ATCn, ATEn, ATVn, AT&Wn, AT&Yn, ATZn, AT&F, AT&Kn, AT#SWPKGV, ATIn and ATI.

Table 3: Example Response

Synchronous Response:

Synchronous messaging is a two-way communication i.e. the information sent as a response of the command after the complete execution from the host. It is followed by the status of the command after execution.

In the above example, the node sends connection request to AP, AP sends response, node gets connected by acquiring IP address, net mask and Gateway.

Asynchronous Response:

Asynchronous Response is a one-way communication i.e. the information is sent as an indication of an event that occurred. This event may be due to the command issued previously.

For example, in disassociation event, when the AP gets reset a message is seen on the module. In few cases, there will be multiple responses. Following are the responses to the command scan:

AT+WS=1<CR> <CR><LF>+WS:C0:C1:C0:A6:7F:3A,"ssid153126173420",1,INFRA,-80,NONE<CR><LF> <CR><LF>+WS:2C:30:33:DC:83:FE,"dd-wrt",1,INFRA,-82,NONE<CR><LF> <CR><LF>+WS:C8:B3:73:4A:33:48,"wifiVirus",1,INFRA,-90,WPA2 PSK<CR><LF> <CR><LF>+WS:98:FC:11:F8:C7:15,"FWUP",3,INFRA,-94,WPA2 PSK<CR><LF> <CR><LF>+WS:68:7F:74:52:6F:D4,"homekit",6,INFRA,-90,NONE<CR><LF> <CR><LF>+WS:00:03:7F:50:00:01,"QSoftAP",6,INFRA,-93,WPA2 PSK<CR><LF> <CR><LF>+WS:00:8E:F2:56:24:04,"GainSpan4",6,INFRA,-79,WPA2 PSK<CR><LF> <CR><LF>OK<CR><LF>

WL865E4-P AT Command Reference Guide

specified is the range of its value.

HEX: Hexadecimal value up to 4 bytes e.g. FF FF FF FF is the range specified is the range of its value. Long integer: A decimal value that cannot be stored in 4bytes value and can be stored in 8bytes value.

The range specified is the range of its value. String: It must be entered in double quote. All the special character can be used within the string. To have

double quote, escape character (‘\’) must be appended, e.g. “Te\”lit”. The range specified is the length of the string.

IP Address: It can be IPv4 address or IPv6 address notation. IPv4 Address: It must be IPv4 notation.

WL865E4-P AT Command Reference Guide

80613ST10987A Rev. 1.4.27 Page 28 of 299 2021-01-17

IPv6 Address: It must be IPv6 notation. MAC Address: It must be in the format (EUI48) i.e. XX:XX:XX:XX:XX:XX. Fixed String: It is a predefined string and doesn’t come in double quote. Hex Stream: It is a stream of hex bytes. The range specifies the length of the byte stream, e.g.

1234aabbcc is 5 bytes long. Binary Data: Binary data is not processed by parser and it is given as is to command processor. It is

always preceded by integer parameter that gives the length of the binary data. The binary data is not echoed by the parser.

As the parameter Data and Data length are mutually inclusive, if either of this parameter is present (optional or mandatory) then the other parameter must also be present in the command.

Example:

AT+NHTTPDSENDDATA=0,0[,0,]

3. ARCHITECTURE

This chapter provides a brief overview of the system and the architecture of Serial-to-Wireless application.

3.1. System Overview

The Serial to Wireless stack is used to provide wireless capability to any device having a serial interface. This approach offloads WLAN, TCP/IP stack and network management overhead to the wireless chip, allowing a small embedded host (for example an MCU) to communicate with other hosts on the network using a wireless link. The host processor can use serial commands to configure the serial to wireless application and create wireless or network connections.

The user will receive a pre-loaded firmware to Run the application. To customize the application user is required to perform the following steps.

3.2. Working Principle

The architecture of the Serial to Wireless interface communicates to and from TCP/IP network commands. These are network management commands of serial to wireless interface. The network connections intercepts using Command Processor. Following diagram represents the sequence of communication between the interfaces:

Driver Interface

Figure 1: Communication between the Interfaces

Serial to Wireless application takes command input from three different IOs. The software configurations can be UART and either SPI or SDIO combinations. The driver interface gives a transparent interface to the AT command parser. AT command parser does the parsing and calls the command processor API to process the command.

Command Status

3.3. System Initialization

Upon startup the serial to wireless interface performs the following actions:

• During the initialization process, the module software tries to fetch the configuration file (also called as profile) from the file system. If the profile is not found, it sets the factory default values to profile and creates the file in the file system. For a default profile, the interface starts in Legacy command mode. User is required to check the mode of the command processing and start the specific operation.

• In the profile, configuration related to wireless network- UDP/TCP/DNS/MDNS are kept. If the auto connection mode is set, then the module will attempt to join the wireless network and tries to open connection based on the UDP/TCP configuration.

• Serial to wireless application is initialized based on the profile settings.

4. HOST INTERACTION

4.1. Interface

An embedded host uses one of the serial IO interfaces to connect to the module. By default, UART0 interface is enabled. When the module boots up, it initializes the UART0 interface to

receive command. Host can enable the second interface by issuing AT command (e.g. AT+YSIF = 1). The second interface supported can be either SPI or SDIO. Both SPI and SDIO supports Slave mode.

By default, the second interface is disabled. User can enable and save it in profile for the next boot where the module automatically starts the second interface. Upon factory reset, the second interface is disabled.

The default UART0 configuration is as shown below:

4.1.2.2. SPI/SDIO Interface Demonstration - +YIDEMO

Description

This command demonstrates SPI or SDIO host interface. To demonstrate the SPI or SDIO interface, connect two WL865E4-P modules through the jumper

wires. One of the module acts as bridge and sends the command received from UART port to the SPI or SDIO port. The bridge simulates the host connected to the WL865E4-P module through SPI or SDIO interface. This command is read by the Bridge module and sends appropriate command to the WL865E4P module via SPI or SDIO.

Following are the command usage in all possible cases:-

1.INITialization: AT+YIDEMO=1, interface type (1 for SPI, 2 for SDIO),clock frequency(KHZ)

2.SHOW Received message AT+YIDEMO=2, display mode (1 for text format, 2 for HEX format)

3.SENDs command to host with '\r\n' appending. AT+YIDEMO=3, Parameter

4.SENDs command to host without appending . AT+YIDEMO=4, Parameter

6.SENDs command to host with '\r' appending. AT+YIDEMO=6, Parameter

5.starts transmit throughput test AT+YIDEMO=5, packet size, packet count

7.initiates receive throughput test. AT+YIDEMO=7, packet size, packet count

8.Stops throughput test in case of receive throughput. AT+YIDEMO=8

9.Display statistics. AT+YIDEMO=9

5. GENERAL OPERATIONS

5.1. System Settings

For basic module setting and to get system information, the following AT commands are used:

• ATEn - To enable/disable echo mode

• ATVn – To enable/disable verbose mode

• AT+YSR – To perform a software reset on the board

• AT+YHD – To get heap information

• AT+YTIME – To set and get time

• AT+YLC – To switch between new command and legacy command

To store information in the internal Flash of the module, file system commands are used. User can open/create, read/write and close the file after the completion of specific operation and then delete the file if not required or not in use.

For a file to be saved in secure mode, a password can be provided during file open procedure. If a secured file is opened with a wrong password or without a password, then file read operation will give junk data. User must track and maintain the password of the files saved in secured mode.

User can list the files present in the internal flash and get information on the size of each file.

5.2. Profile Settings

Following are the set of AT commands for profile setting:

• Profile Read - Zn

• Profile Set - &Yn

• Profile Save - &Wn

• Save TCP Profile - +YPTCP

• Save UDP Profile - +YPUDP

• Profile Clear/Factory Reset - &F

The configuration parameter values that define the behaviour of the node are grouped into Profiles. These profiles are stored in non-volatile memory when not in use. The WL865E4-P node supports two Profiles by default (profile0 and profile1).

Profile includes configuration of layer2 (Wi-Fi), layer3 (DHCP), and Layer4 (TCP, UDP etc.). There are two set of profiles that can be stored in the Flash.

User connects to an access point or creates a network (Limited AP), upon L2 connection. Start the DHCP server and open TCP/UDP sockets for data transmission, all the configuration set up is stored in SRAM.

To save the configuration in flash user must issue AT&Wn (where, n can take 0/1 value based on profile0 and profile1). The profile parameters are saved in JSON format in the file system.

If user enables NCM auto mode, then the system automatically initializes itself with saved profile configuration. After successful connection (layer3/layer4), user can store L2, L3 and L4 (TCP/UDP) socket connection information in Profile.

Following commands are executed to save a specified CID for TCP/UDP configuration in the profile,

• AT+YPTCP

• AT+YPUDP

Following AT commands are executed for reading, setting default and saving the current profile:

• ATZn - To read parameters, from the specified profile. Upon execution of this command, module displays the profile (profile 0, or profile 1) parameters.

• AT&Yn - This command is used to select the default profile. The settings from the profile that are chosen as the default profile are loaded from non-volatile memory, when the device starts.

• AT&Wn - This command is used to save the current profile. Upon execution of this command, the current configuration settings are stored in non-volatile memory under the specified profile (profile 0, or profile 1).

5.3. Default Profile

Default Profile setting provides AT commands to set the default profile parameters. Following are the set of AT commands to set the default profile parameters:

• AP DHCP server configuration - +DPNADSC

• AP Static IP configuration - +DPNAIPC

• AP WLAN configuration - +DPNAWC

• Station Static IP configuration - +DPNSIPC

• Station Retry configuration - +DPSRC

• Station WLAN configuration - +DPNSWC

• Update TCP Profile - +DPTC

• Update UDP Profile - +DPUC

Using this command user can set the default parameters to the profile stored in SRAM, even without validating the profile parameters. To set the AP configuration in STA mode, user can directly set the parameters even without getting connected to it. Similarly, the other profile parameters can be configured without executing the process.

If user wants to save it to flash, to retain these values across boot, AT&Wn command must be issued. Sequence of execution: To put the module in auto mode user can follow the following sequence: -

1. Since all the configuration just saved into profile without applying, there is no sequence for all above commands.

2. Enable NCM auto mode by ATCn command.

3. Save profile into flash by AT&Wn command.

4. Reset the device.
