Just to give an update: I got my Arduino Nano ESP32 back to working normally, but it is a little more complicated: Connecting B1 to GND and resetting activates the firmware download mode. So when I then uploaded a Blink sketch, my arduino was recognized in the ArduinoIDE as an AirM2M_Core_ESP32C3 (e...

Thanks for the help! Just so I get this right, because I'm a rookie: I bring GPIO0 low by shorting it to ground with a resistor (10k?), then press the reset button then upload some blink sketch then remove the short to ground at GPIO0, so it is high/floating (or even connect directly to 3.3V?) Then ...

Hi everyone, my project is a location tracker which is supposed to be in deepsleep most of the time and wake up when moved. To do so I connected my Arduino Nano ESP32 to an MPU6050. The sketch is based on the magic push button (basically a wake-on-motion interrupt with a certain threshold) in this a...
