      @m5stickfreakler actually , change use PortA is a great solution. the GPS Unit Cold start takes time, (maybe 3~5min). the signal quality very important , so had better use it in the house outside.

        Thank you very much.
        Unfortunately it does not work with any port as I have described above.
        I just receive Quality "NO signal". It can stay for hours outside, nothing changes.
        Cold start time is 35 seconds as you can see in technical details of m5stack.

        BUT HERE IS THE BEST:
        I received today 4 new GPS Units and now it works.
        My "old" two GPS units are not working.
        That was it. A lot of waited time

            I bought a GPS Unit from Aliexpress and it seems old since I faced the same problem with @M5StickFreakler. What store should I contact for this issue?
            Just now I contacted the M5Store from the Aliexpress homepage.

              @liemph We have not updated the version of the GPS Unit. It may be that the GPS Unit you are using has some quality problems. Please contact the store where you purchased the product

                I bought a GPS unit recently, and have the same problem.
                I found a simple solution. No need to cut any wires; that's for the Module, not the Unit.

                • Unplug the GPS unit from Port C.
                • Stat the M5Stack FIRE.
                • Plug the GPS Unit back into Port C.

                Without unplugging the GPS unit I experience 100% failures.
                With unplugging before power-up: 100% success.

                The unit is a beauty when working! Acquires 10 satellites in seconds, indoors!
                The power-up sequence is definitely a drawback, but not a deal breaker.
                I wonder if it could be solved with a capacitor or some other simple augmentation?

                    @liemph; I'd be happy to share my code, but all the GPS-related parts can be found in the product examples here:
                    https://github.com/m5stack/M5Stack/tree/master/examples/Unit/GPS_AT6558
                    The example is pretty complete, but unreadable.

                    The project I'm working on is more display oriented, and most of the code is a nascent control class I'm playing around with for solving general display problems. You're welcome to take what you like from it:
                    https://github.com/vkichline/GPSTest

                    I plan to pursue the display controls in another project, so I won't be updating this one.

                        Hi
                        work with M5 stack Fire,
                        the problem is the sensibility, this interface without external antenna is frequent to have disconnection or louse signal inside my home.
                        corresponding of the price.

                        amn
