Arduino Code –Sending SMS
For sending AT commands and communicating with the A6 module, we will use the serial monitor. The sketch below will enable the Arduino to communicate with the A6 module on serial monitor. Before we proceed with detailed breakdown of code, connect your Arduino to PC, compile below code and upload it to the Arduino.
Once you open a serial monitor, make sure that ‘Both NL & CR’ option is selected!
