Eric Jung / Mbed OS mbed-os-example-cellular-BG96

BG96 Cat.M1 basic sample for WIZnet IoT Shield based on Mbed-OS Cellular APIs (SK telecom network in Korea)

Overview

This code could be access via Cat.M1(BG96 module) of SK telecom network in Korea. Need a WIZnet IoT Shield BG96 board and development board. The code forked Daniel_Lee's mbed-os-example-cellular-BG96 repository and added some features.

Tested with

  • NUCLEO_L476RG
  • DISCO_L475VG_IOT01A
  • K64F

Example functionality

This example showcases the following device functionality:

1. Import the application into your desktop:

mbed import https://os.mbed.com/users/hkjung/code/mbed-os-example-cellular-BG96/
 
cd mbed-os-example-cellular-BG96

2. Compile and program:

mbed compile -t <toolchain> -m <TARGET_BOARD>

(supported toolchains : GCC_ARM / ARM / IAR)

3. Download binary to a target board
