gsm module library for STM32 LL (BETA)
- Enable USART (LL Library) and RX interrupt.
- Enable a gpio as output and open drain to connect gsm power button.
- Add gsm and atc library to your project.
- Configure
gsmConfig.h
and atcConfig.h
files.
- Add 'gsm_rxCallback()' to selected usart interrupt.
- Call
gsm_init()
.
- Call
gsm_loop()
in infinit loop.
- If using FREERTOS, please create a task for gsm with at least 512 word heap size.
