On display the date is not updating.

In the display, the date is not updating. it is fixed at 1999-12-31 . the time is correct, the Lat Long is correct and the Locator is correct. Only date is wrong. (verified on two different trackers)

[richonguzman]

did you test this more? as this is really strange behavior

[OK1FWG]

Did you had to reset the GPS? If so, it can happen, that the GPS is not sending NMEA message containing the date,

[iw2ejh]

Yes, on both devices, the GPS has been reset with the available tool. Do you know how to recover from this situation?

[OK1FWG]

You've probably used something like the TTGO_T-beam_GPS-reset utility. I don't have my code at hand right now, but as I remember, the reset utility enables only the NMEA_GGA sentence, which doesn't include the date. I wonder why, but... myGPS.enableNMEAMessage(UBX_NMEA_GGA, COM_PORT_UART1);

I had to add to it something like this: myGPS.enableNMEAMessage(UBX_NMEA_RMC, COM_PORT_UART1);

By using the TinyGPS++ library, it reads just these NMEA sentences: GPGGA, GPRMC (GPS) & GNGGA & GNRMC (Glonas)

Then I've got the date&time displaying correctly. I'll try to find my code at home, please QRX.

Yes Willi, you got the point, I added the RMC sentence after the gps reset and bingo, this unlocked the situation, now the Date appear correctly on the display.

Problem description: Only Date is not updated on the display Cause: have used the GPS reset tool to force GPS to send again NMEA sentences after Meshstastic was loaded on the TTGO board (it use different protocol) Solution: modification of the reset tool to include RMC sentence in addition to the GGA one ( change the wording from disable in enable in the sentence highlighted below (<-------) )

do { if (myGPS.begin(SerialGPS)) { Serial.println("Connected to GPS"); myGPS.setUART1Output(COM_TYPE_NMEA); //Set the UART port to output NMEA only myGPS.saveConfiguration(); //Save the current settings to flash and BBR Serial.println("GPS serial connected, output set to NMEA"); myGPS.disableNMEAMessage(UBX_NMEA_GLL, COM_PORT_UART1); myGPS.disableNMEAMessage(UBX_NMEA_GSA, COM_PORT_UART1); myGPS.disableNMEAMessage(UBX_NMEA_GSV, COM_PORT_UART1); myGPS.disableNMEAMessage(UBX_NMEA_VTG, COM_PORT_UART1); myGPS.enableNMEAMessage(UBX_NMEA_RMC, COM_PORT_UART1); <------ myGPS.enableNMEAMessage(UBX_NMEA_GGA, COM_PORT_UART1); myGPS.saveConfiguration(); //Save the current settings to flash and BBR Serial.println("Enabled/disabled NMEA sentences"); break;

P.S. sorry I do not know how to reduce characters in my comment ;)

I am glad I could help. Enjoy it!

[richonguzman]

thanks a lot for this!

will try to save the info on the WIKI also!

[richonguzman]

i had this all missing!! until I needed to reset one T-beam

so i will upload this all new into a new updated repository
