I am using a Pololu Minimu9 v5. I successfully did a self test of the LIS3MDL 3-axis magnetometer and now I am trying to self test the LSM6DS33 with the procedure mentioned in the application note. My test appears to fail each time. I don't know if it is my method or if the sensor has malfunctioned. What is the proper implementation of the self test? Is there anything you can do to readjust sensor to optimal functionality?
