Hi. I'm using a 3DR optical flow sensor connected to a pixhawk on my quad to enhance the stability of the quad copter when it hovers in one place. I've been having issues saving the parameters I change on QGround control and I cannot access the sensor through the pixhawk to change the parameters wirelessly through the telemetry that is connected. I have to directly connect my laptop to the sensor via USB cable to access the sensors parameters. Anyway to fix this issue so I can see the sensor and any suggestions on how to save the parameters on the quadcopter?
