My group and I are trying to create a device to send a message to a cell phone… that is it.
So far we have a hologram SIM card, and the adafruit FONA 808 – our code is attached.
The problem we encounter is:
a) The device sometimes connects to the network but most of the time it is searching for service, so it is not a steady connection.
b) The device does not send to my phone number. When it should send, it doesn’t. I don’t know what the problem is. is it the format I put my phone number in or what?
c) Finally, my input to the serial monitor doesn’t work. I should be able to input 'i" into the serial monitor and it should return a signal status, but “i” doesn’t even get inputted into the serial monitor.
