mbed-os-example-atcmdparser

ATCmdParser example for mbed OS

Getting started with ATCmdParser

This is a example showing ATCmdParser usage with ESP8266 WiFi module.

The program retrieves the FW version of the ESP8266 module connected over UART using AT commands.

Required hardware for running this example

• K64F
• Seeed-Grove-Shield-V2
• ESP8266

Connecting the ESP8266

To connect the ESP8266 module to your development board, look at the ESP8266 Cookbook page. In general, this means hooking up the ESP8266 TX pin to D1 and the ESP8266 RX pin to D0 on your development board.

Getting started

1. Import the example

   mbed import mbed-os-example-atcmdparser
   cd mbed-os-example-atcmdparser
   

2. Compile and generate binary

   For example, for ARMCC:

   mbed compile -t ARM -m K64F
   

3. Open a serial console session with the target platform using the following parameters:

   • Baud rate: 9600
   • Data bits: 8
   • Stop bits: 1
   • Parity: None

4. Copy or drag the application mbed-os-example-atcmdparser.bin in the folder mbed-os-example-atcmdparser/BUILD/<TARGET NAME>/<PLATFORM NAME> onto the target board.

5. The serial console should display a similar output to below, indicating a successful AT communication:
