Library project for Sim900, Sim800, Sim900A module for Android Things, supports GSM + GPRS operations. Any suggestions and contributions are welcome.
Aim: This module will talk to a SIM900 module over the serial port from any of the Andoid Things supported device. This project will enable you to send and receive SMS in all formats (Although initially only Ascii text sms will be supported), make GPRS network calls, all in just few lines of code.
