I can use Sphero BOLT's magnetometer value just fine in Sphero Edu App using getCompassDirection() in the JavaScript code in the app. But I can't find magnetometer sensor reading in this library. All I could do was to run the calibration procedure where the robot turns around itself.

What's the easies way to reverse engineer BOLT to figure out how to get magnetometer readings? I can decompile the app, but the relevant parts are minified with ProGuard, it seems. Should I try to intercept BLE messages? Could you lead me in the right direction to get this to work?

Thank you for this awesome library!

Yes, that's a good way.
I think you should try to use the magnetometer_north_yaw_notify command
