BNO055 not calibrating Accel=0

by Juaxs on Mon Nov 29, 2021 8:31 pm

Hello,
recently y got my BNO055 imu and im using the Adafruits BNO055 library to get the calibration information and im getting a problem with the accelerometer calibration value.

Code: Select all | TOGGLE FULL SIZE
X: 63.3750   Y: -3.3750   Z: 3.6875   Sys:3 G:3 A:0 M:3


The system is located on a flat surface at the beginning of the calibration process but the A value is always at zero, i don't know why, and that's the reason i cannot get the exact calibration to set the acc offsets.

Im running the restore_offsets.ino example included on the library.

Thank you.

See this page for instructions on how to calibrate the BNO055. The embedded video is helpful.

O have to mention that I’m using the 0x29 address using the 3.3v pin on ADR.

How can I update the sensor using arduino?

It is not possible that SYS = 3 and ACC = 0.
So I expect something wrong in the code or in the communication.
