nRF Cloud Map + AGPS sample

It appears that when publishing AGPS data to  nRF Cloud, the map does not appear as it did back in July. Is there any extra end-device configuration that needs to be done to make that happen? I'm currently using a nearly stock version of the nrf_cloud_agps sample.

Thanks! Slight smile

P.S. This may be due to me using the Asset Tracker example with the first device previously. If there's  a way to enable it though without the full Asset Tracker demo, that would be awesome!

  • Hi Jared,

    the map does not appear as it did back in July.

    Do you mean that the map do no appear at all? (just a blank screen)

    If the device do not send the GPS position to nRF Cloud then the map does not appear at all. 

    e.g. A successful GPS FIX.

    I: ---------       FIX       ---------
    I: Time to fix: 20 seconds
    I: Longitude:  5.399481
    Latitude:   61.362466
    Altitude:   10.276114
    Speed:      0.118597

    D: Tracking SV 26:     used,     healthy
    D: Tracking: 5 Using: 4 Unhealthy: 0
    D: Seconds since last fix 0
    D: NMEA: Position fix
    I: GPS position sent to cloud

    If you take a modem trace we can exactly see why this is.



    I suspect that this has to do with SIM + network configuration.

    The nrf cloud agps sample tries to request and get PSM, but some networks can refuse this. 
    Therefore I suggest that you try to run the sample without requesting PSM to see if this could be the case.

    You could also set this to false then you get LTE to send whenever it can.
