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:
