M5Stack Gray Magnetometer Fails To Calibrate
-
The M5Stack magnetometer fails to calibrate. It appears to me that there's just too much metal around it to calibrate. I removed the battery plug base, but that didn't seem to help. I don't have this issue with other MPU9250 boards, so am concluding it's the metal surrounding the MPU9250 on the Gray. So basically it appears that the M5Stack magnetometer is unable to be used in its current design. If others have had any success calibrating it or using it, please advise, otherwise my assumption is that it's not useable in the M5Stack Gray. (reposted from Products section).
