- This library using my 'atc' library, please download 'http://github.com/nimaltd/atc'.
- NONE RTOS Supported.
- RTOS V1 Supported.
- RTOS V2 Supported.
- SIM800C tested.
- SIM800 tested.
- SIM800H tested.
- 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.handatcConfig.hfiles. - Add 'gsm_rxCallback()' to selected usart interrupt.
- Add 'gsm_callback_simDetectorISR()' to sim detector interrupt. //if use sim detector
- 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.
