Hello.
I have an ESP32 that works in AP Mode.
When its RX0 (GPIO3) and TX0 (GPIO1) pins are connected to a CubePilot, I can't connect to the ESP. If I remove the connection I can connect to the ESP.
I think that the pins are somehow pulled HIGH or LOW and the ESP32 doesn't work properly.
What other pins can I use ? The ESP is a Wroom-32.
I also have a Wrover-B at hand.
ESP doesn't boot when its RX0 and TX0 are connected

Don't connect 5V circuits to the esp32. You will need to use a level shifter.

Reading through CubePilot documentation it seems like the ports operate at 3V3lbernstone wrote: ↑Wed May 05, 2021 5:12 pmDon't connect 5V circuits to the esp32. You will need to use a level shifter.
