Why can't the compass in the mpu9255 be calibrated?   The sensors are essentially the same quality, just the mpu9255 is not in production and so it's difficult to obtain quality parts.

Hi Sean,
thanks for your support! my IMU is now running and can be calibrated.
Apparently it was mainly due to a bad cable connection to the Raspberry.
I have now installed the image from November 2021, which also runs very well. However, the web interface now speaks German in a funny translation.
Switching the browser to English does not change the language of the web interface....
If it's helpful, I'd be happy to send you a PDF with German terms that fit better in the web interface and submenus. 
Just let me know....

Calibrating the MPU9250 on the desk at home was no problem. On board, however, the compass keeps drifting and needs to be readjusted. I bought a total of 5 MPU9250s. 2 were defective from the beginning, one I destroyed, 1 could hardly be calibrated even at home, the last one then went on board. It was obviously not easy to get good MPU9250. And now I hope that the ICM-20948 I've obtained has a better quality.

Many greetings
Moeritsen

It should use whatever language the browser uses.   You may have to clear the browser cache though.

The translations are automatic but I did recently have some german contributions, see:
https://github.com/pypilot/pypilot/blob/...essages.po

It maybe already better but if you see any terms there that should be changed, open a github issue or make a pull request, or email me and I will improve the translation.

The icm20948 seem to have better quality but I did receive some bad ones.   Now the price has doubled (again) though, so the price is 4 times from a year ago.
