Hi… I’m sorry if this is not directly related to Meshtastic, but is a bit more related to general hardware.
I bought a ttgo t-beam and i think the gps module might be broken. I cant get any GPS data in any application, or any of the test programs or the serial pass through. I haven’t been able to get any indication that the GPS module is active at all via the serial interface.
The board version is a T22-V1.0 20190612 with a Neo-6M GPS. I’m aware that it requires the correct setup of the power management chip to enable GPS.
I also read that in some cases, the GPS chip will only work reliably at a reduced baud rate (4800), but no deal.
I tried quite a bit of fiddling with settings, pins, addresses and speeds at this point.
i’m aware that there is both https://github.com/LilyGO/TTGO-T-Beam (with an updated program for this board version) and https://github.com/Xinyuan-LilyGO/LilyGO-T-Beam.
Any ideas how i can verify that the GPS chip is … well, even reachable at this point?
