If I connect a receiver to the generic UART port on the cube using only the GND and RX pins, will the autopilot recognize the receiver, or is their some handshake logic? Assuming no flow control for UART. Looking for a receive only connection between the autopilot and a receiver for a hand controller.
@dmiller This is an ardupilot query best to discuss it on http://discuss.ardupilot.org . But to answer your question, yes it is possible. You will need to configure the SERIALx_PROTOCOL parameter. Refer Multiple Radio Control Receivers — Copter documentation for more details.
