Good morning,
Im looking at building a module for my gate, where a user can call the gate and it will open. So Im looking at a GPRS module that I can put a Pay-as-you-go SIM card in, however I cannot find any documentation on how to recive phone calls on the Ardunio, the idea being to detect a phone call, look at it the number and if its an “allowed” number then to open the gate, if it isnt dont do anything, or reject the call.
Does anyone have any documentation on how to recive calls, or text messages from the SIM card using the SIM modules?
Thank you
