Hi,
I am communicating SIM808 with nRF52840. I have made changes in libuarte example and send AT commands to send SMS. I have the following question.
- How can I know that I have received complete data?
- How can I send (char) 26 (termination character) at the end of SMS?
- Is there any library available for sending sms and MQTT communication?
Thanks!
