APMRover MAVPROXY Not Setting Relay

Ground Control Software MAVProxy

# python mavproxy.py --master=/dev/ttyACM0 --baudrate 115200

I have successfully set up mavproxy on a raspberry pi and have connected to the APM. I can turn the relay on using mission planner commands.

I sent to following command to the APM.

“relay set 0 0”
(using false or NPN logic)

The relay state does not change.

I also tried

“relay set 0 1”

The relay state did not change as well.

Is there something I’m missing?

My goal is to turn on relay 0 using mavproxy.

Did you set the appropriate relay parameters? (http://ardupilot.org/plane/docs/parameters.html#relay-parameters)
