I have a raspberry3 with navio2 running ardupilot.
My Receiver is a x4r from frysky, capable of transmitting telemetry Data to my Transmitter.
I’ve read a lot about smart Port Cables and Converter to uart. But i’m still confused.
All desriptions in ardupilot Wiki refer to a pixhawk flightcomputer.
Do you have any suggestions which cable or converter i need, to connect my Receiver to my raspberry / navio2.
My Receiver was shipped with a cable for the smartport (4 pins), the cable has a 3 pin connector on the other side (one pin isn’t connected). Can i use this cable? And where to plug on my flightcomputer?
From ArduPilot docs you should connect SmartPort to Navio2’s UART: GND - GND, TX and RX - SmartPort’s data pin.
Run ardupilot with -C /dev/ttyAMA0, set SERIAL1_PROTOCOL to 4 (Standard SmartPort telemetry) in GCS and reboot.
I don’t have Transmitter which support telemetry input, so I can’t test this.
thank you for the Links.
After ordering the parts and some soldering, I testd the telemetry. But it doesn’t work.
The I’ve conntected the converter cable between smartport of my receiver and uart port on Navio2
