I have a few APM in use.. but got a PX4 to test a new system. Did all the config and setup of the IOBoard. Telemetry (3DR 433 MHz) on UART5 and PX4Flow on the UART2.. where I get stuck is the RC.TXT file. Where do I find an example what I have to put in to get both UARTs assigned.
Anybody has a clue?
