The pins for the Fona are attached to soldered points on an e-Paper shield (electrical connectivity has been triple checked and is fine). Pins D2, D3, D4 are all straight passthrough on the eInk board.
I am using the FONAtest program after having run the 3G Baud Rate program.
Issues I am having:
- A lot of the time, timeout is occurring and the board is not being detected
- The red and green lights come on every minute or so but turn off after a few seconds.
- If it does happen to connect, the following will be shown on Serial (note that I tried to call the command b to see the battery voltage. At first it seems to fail but then shows the voltage):
- Code: Select all | TOGGLE FULL SIZE
Initializing....(May take 3 seconds)

This has left the board unusable as I am unable to send commands to it before it turns off.
Please note that the Key pin has been grounded.
Please could I get help with this issue, is it simply that the battery voltage is too low?
