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.


    Does anyone of you have an idea?

    Thank you very much and best regards

    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.
