I use CUAV Nora, Arducopter 4.3 Firmware, Radiomaster TX16S MK2
I connected using the GND pin and TX pin in the TELEM2 port.
I binding the receiver to D16 Telem ON mode.
I also binding to D8 mode, but it does not work.
Change the parameters as described in the Ardupilot Document.
SERIAL2_PROTOCOL = 10
SERAIL2_OPTION = 7
I tried all the methods in the document, but I couldn’t solve the problem.
