Hi everyone, I’m trying to connect my Orange PI 3 to Pixhawk with telemetry. I make the connection below:
I also enable the uart from the config file according to user mauel of the Orange PI and my UART3 port is active:
When I run “mavproxy.py” in the command line I’m getting the output below:
Auto-detected serial ports are:
/dev/ttyS0
/dev/ttyS1
/dev/ttyS2
/dev/ttyS3
/dev/ttyS4
/dev/ttyS5
Only the ttyS0 and ttyS3 active among them. ttyS0 is the three port you can see in the pinout. ttyS3 is the ports that I connected.
My connections are true, I even tried to switch TX and RX, I also tried different baud rates (57600, 921600) but whatever combination I tried, I always get the MAV> link 1 down output from the mavproxy.
Am I missing something? I can connect raspberry to the pixhawk with same configuration.
Note: I completed all the steps in the links below
Download and Installation — MAVProxy documentation 1
Communicating with Raspberry Pi via MAVLink — Dev documentation 1
I also tried to connect it with USB-UART but same thing happened.
