Before throwing the MPU9150 in the PCB bin, I decided to give this sensor another chance with V7.0, and, surprise, it worked !
Back again to v7.1, values were replaced by the same "NaN" string ;
But after a reset in OP's I2C tab, when re-activated, the sensor got alive again ! Then, after a calibration process, the same error message displayed :
Failed to execute RTEIIipsoidFit.m. Only
min/max calibration available
Eventually, after activating the sensor, same "NaN" strings were displayed in place of the values.Reset in I2C tab, and back to work !
This seems to demonstrate a kind of incompatibility between this MPU9150 and the Ellipsoid calibration process.
Hope I will not have the same strange behaviour with the awaited MPU9250...
Sailoog, I will read care fully the info in RTIMULibx in the meantime...
