Hi There,
I have the Adafruit Fona GSM module (Adafruit FONA - Mini Cellular GSM Breakout - SMA Version [v1] : ID 1963 : $44.95 : Adafruit Industries, Unique & fun DIY electronics and kits) and have wired it in following these instructions to my UNO (Arduino Wiring | Adafruit FONA | Adafruit Learning System). However when I compile and run the FONA test sketch from the examples it says this in the serial monitor;
FONA basic test
Initializing....(May take 3 seconds)
Attempting to open comm with ATs
The example code I am using if from the FONA library (GitHub - adafruit/Adafruit_FONA: Arduino library for the Adafruit FONA). I would post the code directly here but it exceeds the forums character limit.
It is meant to display a menu once it has detected the FONA GSM. I have checked that my pin outs are correct and the GSM module is getting the correct power supply (4.1V 2A).
I'm really at a loss as to why i cant seem to run the test sketch...
