Gyro not calibrated warning, loss of control

(Jacob) #21

Hey @ROV, sorry to hear about your trouble. When you have a chance to troubleshoot with the ROV again, let us know. You may arrange a technical support appointment with us by emailing support@bluerobotics.com.

In the meantime, it’s always good to revisit our software setup and complete the step by step instructions again.

You can also see if any of the troubleshooting steps on ardusub.com are relevant for your situation: https://www.ardusub.com/troubleshooting/troubleshooting.html

When you have an error or warning message that you want to ask about, please try to write down exactly what the message says so that we can narrow the problem quickly (with ctrl + f to find it in the code!).

The ‘yaw realignment’ message is benign, but might indicate some distortions in your local magnetic field.

If you continue to have trouble, please write down the error message you see and let me know exactly what it says.
