Hi,
MPU6050 temperature does not match the specific BMP280 temperature measurement.
The current calculation for the temperature is:
temp = (rawTemp + 12412.0) / 340.0;
But the datasheet (MPU-6000-Register-Map1.pdf) specifies:
Temperature in degrees C = (TEMP_OUT Register Value as a signed quantity)/340 + 36.53
36.53 * 340 = 12420020, so the error should be in the formula.
Using this calculation will give the right value:
temp = rawTemp / 340.0 + 36.53;
In this case, the small difference vs. BMP280 can be justified as the internal heat of the gyro.
