I am trying to make a module with the help of Android Things. I need to send temperature and pressure readings to a server over the internet with the help of GSM/GPRS modem. I am using Raspberry Pi 3 with AndroidThings SDK. I am able to get temperature and pressure readings with the help of BMP 280 sensor but must use external GSM modem to send data to the server. Is it possible to integrate GSM modem with Android Things (Raspberry pi 3)? Where can I get resources to learn and do this, as I am new to Android Things and IoT?
Yes, this is possible. Thanks for all the answers above. I worked on integrating SIM900 module in Android things with Raspberry Pi 3 board. I made a sample library project on GitHub as well. I thought It would be helpful for others. Link: https://github.com/MacSimmy/Sim900AndroidThings
