Thanks, you were spot on:)

know it is not recognizing the GPS, it stuck at GPS initialization.

Try other chargers, your only chance is that the charge current is high enough so that the ESP can boot. The position on the charger is also important, the coil in the ESP should be aligned with the send coil. Try different positions. If you put it on the charger, it will try to boot, this is normal. When the it completes the boot, I will shut down again with the message voltage is low 2.8V. Just let it sit on the charger then for a couple of hours. When it is stuck in the bootloop, try another charger, and other positions.
Greetings, Jan.

Thanks Jan.

unfortunately all my attempts to restart it have failed. I have tried all the different positions, tried charging it for several hours, bought a different charger and tried all the same things. I think the battery is fried unfortunately.

i have three of these. 1 still works, the other one doesn’t even take a charge now even though it still has power. I reflashed it, but didn’t help, so I think the coil might be fried.

I did try today with the M10 @ 115 kbaud, it seems to work here with the new firmware. I upload SW5.92 to github with 115k support. I guess the old firmware will not test for 115k. Can you check your serial output when "Autodetect@boot" is set ? It should look like this :

The ublox M10, this is the Beitian BE xx series, is the sweet spot now ! This module has the lowest power, and the highest sensitivity, and can be set to "high navigation rate". Although the M9 series (Beitian BK series) han handle a higher sample rate (up to 25 Hz), the power consumption is higher and the sensitivity is lower. The M8 (Beitian BN series) is the oldest one, with a high power consumption and lower sample rates.
I use always the Beitian BE182, small formfactor, but a thicker ceramic antenna as the BE180. The BE122 is the smallest, but has solderpoints in stead of a connector.
