In this test, we will use AT Command to communicate with SIM900A module. If we send command “AT” the module should reply “OK”. And if that happen, this means the connection is succesfull. To do this, we need an arduino sketch like below : #include <SoftwareSerial.h> SoftwareSeria...

Many GSM modems, WiFi and radio modules can be controlled by sending AT commands over Serial. TinyGSM knows which commands to send, and how to handle AT responses, and wraps that into standard Arduino Client interface. This library is "blocking" in all of its communication. Depending on the...
