RFD868+ telemetry connection


I want to use the navio+ with the RFD868+.

At this moment the RFD’s are connected solid green
Earlyer i configured autostart sudo APMrover2 -A udp: > /home/pi/startup_log &
This works perfect

Now i want it to connect the mission planner via UART with the RFD868+, but i can’t get the connection

I tried sudo APMrover2 -A udp: -C /dev/ttyAMA0 > /home/pi/startup_log &
but it doesn’t work

Can anybody help, thanks!

Please try to connect both radios to a computer and use terminal to check that data is being transfered between them.
