Since this evening, my T-Beam v1.1 (running firmware 1.1.33) does not start anymore.
The red LED starts glowing for a second and then turns off. The last couple of messages on the serial line are here:
Charging enable is enable
Charging target-voltage : 0x2
end when the charge cure
00:00:00 Read RTC time as 0 (cur millis 188) quality=0
00:00:00 WANT GPS=1
00:00:00 Setting GPS power=1
00:00:00 Connected to UBLOX GPS successfully
…and that’s it.
This happens with or without a battery (blue LED glowing, indicating charging).
I also cannot connect using esptool (“connection timed out”) to read out chip_id or anything, making this one a nice brick.
Any idea what’s going on? This T-Beam worked perfectly before.
