UG370: Wireless Xpress AMW007 Kit
User's Guide
The AMW007 evaluation board is an excellent starting point to get familiar with the
AMW007 Wi-Fi module.
KEY FEATURES
The evaluation board includes everything a developer needs to exercise the AMW007’s
UART interface and demonstrate data transfer over Wi-Fi. The board can operate standalone by connecting a PC to the on-board CP2102N USB-to-UART bridge device. Alternatively, the board can be connected to a Silicon Labs EFM8 or EFM32 starter kit, where
a EFM8 or EFM32 microntroller can communicate with the AMW007 over UART.
The kit includes the following:
• AMW007 Evaluation Board
• 1 x micro USB cable
• Getting Started card
• The AMW007 can connect to an existing
Wi-Fi network or be a Wi-Fi access point.
• UART interface and flow control pins use
Gecko OS command API to connect and
communicate across Wi-Fi
• Breakout test points for easy interface with
prototype boards
• Power sources include USB and EXP

Getting Started
1. Getting Started
Software
To set up the software for the AMW007 kit, either install Simplicity Studio, available at https://www.silabs.com/products/development-
tools/software/simplicity-studio to use Xpress Configurator or install a terminal program (e.g. Tera Term).
For most userss labeled AMW007, it will not be necessary to install a virtual comm port driver in order to interface with the AMW007 kit
using the on-board USB-to-UART bridge. Please see the section below for details.
AMW007 evaluation boards labeled AMW007-E04.2 or higher that are connected to Windows and Linux machines should be configured to this driver automatically. However, if the board is not automatically recognized by the operating system, please download and
install the latest version of the CP210x VCP driver: https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-
drivers
Hardware
To set up the hardware for the AMW007 kit:
1. Connect the micro USB cable to AMW007 board and the other end to the PC.
2. Ensure the two blue LEDs labeled USB and 5V near the USB connector are on.
3. Connect to the virtual COM port using the terminal program.
• For Windows, use a terminal program (e.g. Tera Term) set to 115200, 8N1.
• For a Mac, the terminal can be accessed using [tty.usbserial]. There may be a modifier at the end of this for your computer.
Type [tty.usbserial_modifier 115200,8n1] to set the connection to the right settings. If using a utility like CoolTerm, make sure
the settings are configured to 115200, 8N1.
Note that AMW007 kits labeled AMW007-E04.2 and higher that are connected to Windows or Linux machines do not require a driver to
be installed in order to communicate with the board. However, if using a Mac or if the driver does not automatically install, please download and install the driver from https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers.

Check the Version
After connecting the board to the PC and opening the terminal program, press the [[RESET]] button on the board. You should see a
header with the version information for the device. Ensure this version is 2.1.5 or newer. If you find you are using an older version of
firmware, perform an over the air update on the board as described on docs.silabs.com.
help
The [help] command provides information both for commands and variables on the device.
Variables are system-level variables that determine the configuration of the AMW007 module.
Commands are actions that can be taken.

Claiming Your Device
The Zentri Device Management Service (ZentriDMS) tracks GeckoOS devices, their owners, their firmware configuration and many other details. The DMS handles Over-the-Air (OTA) updates, providing a secure way to update devices in the field. You need a free DMS
account before using DMS features like OTA.
To create an account go to the DMS Signup page. The DMS username (your email address) and password you register are used when
you claim your device. To claim your device, in the terminal, issue the dms claim command:
GeckoOS command Description
dms claim YOUR_DMS_USERNAME YOUR_DMS_PASSWORD
Request POST /claim
Connecting (https): ota.zentri.com:443
Starting TLS
{"result":"ok"}
claims your device. GeckoOS response shows a successful result
Once you have successfully claimed your device, you can OTA.
Performing an OTA
Use OTA to update to the latest version of your device's GeckoOS product, or to load a development GeckoOS device with a specific
GeckoOS product or version. You need to claim your device before performing an OTA. See above.
To OTA, in the GeckoOS terminal, issue the ota command:
