Hi guys,

Thats works fine when is connectet direct to the receiver.
When I connect it to serial2 of my speedybee f405 wing it does not work.

|SERIAL2_OPTIONS|0
|SERIAL2_PROTOCOL|15

If have testet also with Option1

Do i need external inverter?

yes the problem is the f405 cannot do inverted serial. so you need an external inverter or change your esp32 to use non inverted serial.
