I am using the FONA 808 shield with an Arduino Uno. When I attempt the use the GPS through FONAtest I get a response of "GPS off" using option 'x'. Below are the responses that I receive.
FONA> O
---> AT+CGNSPWR?
<--- +CGNSPWR: 0
---> AT+CGNSPWR=1
<--- OK
FONA> O
---> AT+CGNSPWR?
<--- +CGNSPWR: 1
FONA> x
---> AT+CGNSINF
<--- +CGNSINF: 1,0,19800105235953.000,,,,0.00,0.0,0,,,,,,0,0,,,,,

Re: GPS off
wait a few moments and try sending 'x' again - might need a bit to get spun up?

Re: GPS off
I waited about 20 minutes and checked again. It is still saying GPS off. I verified that the power status was still 1. Any other suggestions?

Re: GPS off
I do. It is a bgps1403a2 from Seeedstudio which I had laying around.

Re: GPS off
can you take a clear photo of your entire setup? include the GPS antenna and the FONA808 connection

Re: GPS off
are you positive thats a passive antenna? that would make it not work. you really need it to be the right kind :)

Re: GPS off
I have not found anything saying it is definitively passive. I ordered one of yours that should be here in a few days, so I will try that theory when it arrives.

Re: GPS off
I'm having the same issue as well. Using "O" to turn on the GPS but the "x" command returns GPS Off. I have the Fona 808 and the recommended antenna that was listed on your site.

Re: GPS off
ok lemme check this out with a FONA808 - the code may be broken (but also make sure to get a passive GPS antenna!)

Re: GPS off
I just received my new antenna (part # 2460) and I am getting the same results as before; GPS off.

Re: GPS off
I was finally able to get it working for about 2 minutes. I didn't touch anything and now I get the GPS off again. Not exactly sure if I did anything differently.

Re: GPS off
ok updated the code so it now prints 'no fix' rather than GPS off

dont forget, you need to have the antenna outside, pointed at the sky, and it can take many minutes to get location fix!

Re: GPS off
dont forget you can turn on raw NMEA out when the GPS is on and read out the raw data, this will tell you what satellites are visible
