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.

Or


- 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
