I recently got two 868/915 T-Beams and have installed 1.2.45 Firmware on both of them. The first one is working perfectly from what I can see, but the second one still hasn’t shown a GPS fix in several hours. When I first flashed the problem board it gave me the #5 critical error, which pertains to the GPS module (these have 6M chips). I reset the board, and re-flashed it earlier and this message hasn’t appeared again, but has never indicated anything but “NoSats” or “NoGPSLock”.
My first question: How would I know if the chip is outright bad vs just not seeing a signal? The Critical Error#5 on my initial startup has me paranoid about the functionality of the NEO-6M on my board.
Second question: I’ve seen some users on here posting verbose output from the ESP32 that contains a lot of information about various chips like the AXP and the GPS module. I’ve also seen users uploading code directly to the ESP32 to control the NEO-6M and AXP configuration. What I can’t find is the step-by-step on how this is done. What is the best resource for learning how to get serial output from my TBeam and to configure the GPS chip?
Thanks! I’m very excited to be a part of this community
