Test code that Cat.M1 of BG96 for SK Telecom in Korea

This example showing how to use Cat.M1(BG96 module) of SK telecom network in Korea. You need a WIZnet BG96 board or can connect directly to M2Mnet BG96 module and development board.

  • If you are using Mbed OS 5.11.5 version, please see here!
  • Pelion ready example code is here!

  • BG96 RESET = D7
  • BG96 PWRKEY = D9
  • BG96 RX = D0(or D2)
  • BG96 TX = D1(or D8)
  • BG96 VCC = VCC(5V)
  • BG96 GND = GND

Tested with

  • NUCLEO_F429ZI
  • DISCO_L475VG_IOT01A
  • K66F
  • K64F

Below boards are Need to connect board's D2 and D8 to BG96's TX and RX on mbed_app.json

  • NUCLEO_L152RE
  • NUCLEO_F401RE

 "QUECTEL_BG96.tx": "D8",
 "QUECTEL_BG96.rx": "D2",

1. Import the application into your desktop:

 mbed import https://os.mbed.com/users/Daniel_Lee/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

4. Result
