Problems with the GPS-Module



  • Hello everybody,

    I try to use the GPS module with my M5CORE Gray.

    I tried the example for the GPS module, but it didn't seem to receive any satellites. I have also put the device outside for a long time, but still no signal.
    The only thing that works is the time.
    I use the external antenna.
    Here is the output from the GPS module.

    *$GNRMC,153551.00,V,,,,,,,190220,,,N*6D
    $GNVTG,,,,,,,,,N*2E
    $GNGGA,153551.00,,,,,0,00,99.99,,,,,,*7E
    $GNGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*2E
    $GNGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*2E
    $GPGSV,1,1,00*79
    $GLGSV,1,1,00*65
    $GNGLL,,,,,153551.00,V,N*52*

    Does anyone of you have an idea?

    Thank you very much and best regards
    Simon


  • M5Stack

    Signal from external antenna will be much stronger than PCB antenna



  • I found out what was wrong.
    The external antennas from my two GPS modules were both broken.
    After a long time, the module found satellites with the internal antenna.



  • I suggest you to use internal antenna because it's portable and not easily damaged.
