When I connect the board, only the green power LED lights up, but it is not recognised. I have tried to reset it manually by connecting pins B1 and gnd and pressing the reset button but the purple led does not light up, only the green one, so the board is still not recognised.
Hi, which operating system do you use? In my case, it was necessary to install the Windows driver for the USB-to-serial converter on the ESP32 board.
I use windows 10, the thing is that it worked a few days ago and today it doesn't and I don't understand why. I appeared in the device manager in the Ports section (COM and LPT) but no longer.
I'm not familiar with the Arduino Nano ESP32.
Any chance that you're using a different (charge-only) cable this time?
Nope, im using the same cable
If the board is connected, for example, on a breadboard, disconnect it and try without any device connected
