Dears,
I left mij V1.1 charging overnight, but put in sleep mode.
When I returned in the morning, I was not able to get the module out sleep mode. I pulled the battery and reseated. (Battery voltage : 4V).
The red led on IO4 burns for 1 second, then goes out. During this 1 second the board works. But when the light goes out, I loose the ESP connection, also not able to connect over serial.
What can I do to revive the board? The 1 second is also too short to reflash something, I tried, but always looses power at around 14%.
Tried also long pressing the buttons or button combinations, no luck, always after 1 sec everything goes dark :-(
Thanks!
