I just returned to my IoT project. Pulled esp32 from box, connected with usb cable to
raspberry pi, did
minicom -D /dev/ttyUSB0 and .... nothing. No reaction to my input,
help() doesn't work. No output.
Have I bricked another ESP32?
I thought so, then I started to play with options in settings and voila!. Here is reason for such strange reason: hardware control was turned on, and apparently ESP32 doesn't work well with it.
How to get to it?.
Ctrl-Alt-Z O, then
Serial port settings.
