Also attached the log file for your reference. please suggest. We do not have sim connected and hope it does not make difference2020-03-02T09_18_25.803Z-log_GPS.txt to latch GPS network.

Thanks in advance

  • Hi Pavan,

    Correct, you do not need a SIM card to get a GPS fix.

    What hardware are you working with? A custom board, nRF91DK or the Thingy:91?

    Either way, I recommend using an external antenna for the best performance and you should also have the device in an open area or at least outside a window since gathering GPS data from satellites can be quite sensitive, so if you have many restrictions between the device and the satellites you may not get a fix.
