GPS error: (None, None) coordinates
I am using a Pytrack with my FiPy, and trying to get a location with the L76GNSS lib provided by Pycom.
When getting coordinates, the method always gives me empty data, even after 20 minutes. I tried indoor and outdoor, always the same results.
Is there some kind of initialisation that must be done before ?
Does someone have the same issues ?
Edit: I have two FiPy/Pytrack at my disposal and they both gives the same output.
Thank's for your replies !
I though that the module couldn't catch signal for indoor, and this is why I tried outdoor. I had buildings around me but clear a view of sky for about 20 minutes and still no data.
I've tried printing the frames, and I only get invalid data:
- V means invalid data,
- N means no fix for GPS
I started digging into the protocol specification for L76 device and saw multiple commands to configure it.
Do you know some that may help getting better signal ? (I found Active Interference Cancellation for example, but it is activated by default).
Thank's again !
Without any additional hard-/software?
Have you tried to print the sentences read from the GPS chip?

GPS indoors will just not work and outdoors you need clear view of the sky.
Perhaps that's the problem?
