Hi @jtsheedy -  
Are you able to send at 10hz? The Autopilot may require it at that or faster in order to use…  
This python script referenced [here](https://discuss.bluerobotics.com/t/high-accuracy-aftermarket-imu-gyro/13284/24) can be used to test functionality, as it demonstrates heading and position can be sent…

If you continue to have issues, please share a sample output of the messages being sent and a .BIN autopilot log from when the system was armed with the output streamig and serial2 configured to udpin 0.0.0.0 - thanks!
