Fona 808 GPS Serial Commands Error

Post by PandaPorc »

Hi,

I've set up my Fona 808, and all functions seem to be working apart from the GPS readout. I'm on a Raspberry Pi 5 and communicating over serial myself instead of using the library. When trying the commands I've found from the datasheet this is the response:

Code: Select all

AT+CGNSPWR?
+CGNSPWR: 0

OK
AT+CGNSPWR=1
OK
AT+CGNSSTATUS?
ERROR
AT+CGNSOUT=255
ERROR
AT+CGNSINF
+CGNSINF: 1,0,19800106000035.000,,,,0.00,0.0,0,,,,,,0,0,,,,,

OK
I've spent hours searching the internet for any sort of other reference as to the serial commands for the Fona 808 to make sure I'm not messing them up or that something hasn't changed between versions, but have found nothing. This is the antenna I'm using:

Thank you so much for any help in advance, I'm really at a dead end here.

Worked it out, it's another detail not fixed in the datasheet:
