Small update
I have tested the project TTGO T-Beam Tracker for The Things Network again.
The display seems to work, only the display for the battery does not work.
Apparently a new library has to be implemented.
But GPS reception is there, the time has been determined and a location is available after a few minutes.
The display shows the current position data quite quickly every 20 seconds.
These values can then be recognized:
Latitude: 48.XXXXXXXX
Longitude: 8.XXXXXXXX
Error: 1.00m
Message queued
I think “error” means as much as accuracy.
1.00m varies from 0.9m to 1.9m
But well, joining the LoRa network still doesn’t work.
