Hello Community,
I now have 3 FireBeetle 2 ESP32-E (DFR0654) in use.
The same program is installed on all 3 ESP32s.
2 of these 3 ESP32 are running without any problems. One of the ESP32s is behaving strangely. If it is connected via USB-C, regardless of whether it is a PC or just a power supply unit for charging the battery, after the first deep sleep ...
rst:0x7 (TG0WDT_SYS_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
invalid header: 0xffffffffff
invalid header: 0xffffffffff
... only a reset will help here. But then, after the RTC-WakeUp, the same problem appears.
This morning I noticed that it probably only occurs when the battery is charging (Charging Indicator lights up red).
What is the reason for this? I don't understand why 2 out of 3 don't have this problem.
Many thanks in advance for your help.
Best regards
Nico
EDIT: I tried to cut the low-power solder jumper pad on one of the three. I tried it with a cutter knife, but couldn't see any visual difference, so I thought it didn't work. But I don't know which ESP32 it was that I tried it on. Could that explain the problem? I can't find any information on this in the FireBeetle 2 ESP32-E documentation.
