I start to test the Module and I could not change the mode with the Button, the module blink only 6 times red. Is there in other hack to change the mode?
Then I tried to change the firmware with micro python but the ESP32 sends only invalid header: 0xffffffff after flashing. The ESP32 should work with the standard firmware or is there any difference?
If I want to change the firmware back, is there a manual to flash, it?
