No data from GPS even when fix led blinking #34

Note that some of the TTGO T-Beam devices come with GPS module preprogrammed in a way that will not work with this software. What fixed it for me: set board in Serial Passthrough mode between Serial and Serial1, both at 9600 baudrate. Then use ubxtool -p RESET -f /dev/YOURSERIALPORT to reset GPS to default settings. Afterwards flash this software and it will work.

Suggested fix in the software: add GPS module reset command at boot.

Same problem here. After ubxtool -p RESET -f /dev/YOURSERIALPORT the red led ist not flashing any more. GNSS_version() returns GNSS_MODULE_NONE on TTGO T-Beam T22 V1.0 (GPS TX=IO34, RX=IO12).

Try resetting it again? It took a few tries for mine to catch up.
