Howdy! So I made a recent purchase of two Lilygo tbeam m8n boards. One was DOA, the second board is having GPS issues.
The GPS was working on the board a couple days ago with the stock antenna, the signal got progressively worse. Yesterday it stopped working completely. Today I received a beefy good quality 25mm GPS antenna. The board is still unable to get a lock on an sats even when left outside for a couple hours. Any ideas on what the issue might be?
Things I’ve tried already:
Re-flashing firmware to lower versions.
Update. After a full day of being operational by installing the 1.2.59 firmware, it now has a Critical fault #5… Board was powered down for about an hour or two.
Hi there
I do have the very same issue on three TTGO T-Beam V1.1 / SX1262 / NEO-M8N modules. Worked for a couple of hours on v1.2.57.f7c6955, GPS reception started to be flaky. Upgraded to v1.2.59.d81c1c0, one was ok, two never got any GPS signal. Had them off for the weekend, today all three get no GPS signal even after several hours outside with a clear an open sky view.
