    Hi Robert,
    i have a question:
    I try to readout the myGPS with the Program GPSTime (https://www.coaa.co.uk/gpstime.htm) to corrects the PC clock.
    But every connect from the App to myGPS initiated a reboot on the Arduino and the App gets a timeout.
    Is the a bug in the App or in the Arduino?
    Thanks for help.
    Best Regards
    Andreas

    Its in the arduino. When connecting serial port it drops connection and forces a reboot.

    You overcome this by wiring a 470uf 30V electrolytic (bipolar) capacitor between RST and GND of the Arduino.

    The capacitor would need to be removed if you ever update the firmware though

    Regards

    Hello Robert,
    yes it works! No Reboot any more at connect, Thanks.
    Now i have to check why the GPSTime set my PC to 1.1.1970 then to 31.10.2038, then to 14.6.2007....
    The OLed display shows the correct Time.

    Hi Robert,
    the GPS Time App doesn't work, only silly Date and Time values.
    Did you know a "good" App to sync the PC Clock with myGPS?

    Hi Robert,
    thank´s for the Apps.
    There are all working, show´s the right Position, Satelite and Date and Time values.
    But all the sync GPS- PC-Time Apps i try doesn´t work...
    (GPS-Time, GPS-Sync, Atomic-Time and so on) Some of this have a "Logger", all data are correct, but no Time-sync....
    Maybe there use some other Nmea-values?
    Thanks for help
    Best Regards
    Andreas

    Hi Andreas
    I will have a look to see if I can do a Windows app that will take the GPS messages from the controller and give an option to set the date time on the PC, is that what you are trying to do?
    Regards
    Robert

    Hi Andreas
    I have written the SW and about to test. It appears to work but I want to do more testing before releasing here. Please email me directly and I'll send you the SW to test

    Regards
    Robert
