We warm start the BHI260AP with calibration profile that we already saved when Acc and Gyro accuracies were 3. I have a few followup questions: - In running mode, the gyroscope accuracy drops to 2 or even 1 when the system is stationary for a few seconds, it may not go to 3 if shortly after drop the system moves. On the other hand Acceleromeyer accuracy drops to 1 when the system slowly tilts along roll or pitch angle to ~50 deg. I think these motions tricks the sensor that a calibration procedure is going on. We have also observed that calibration profile changes exactly when accuracy value switches. How can we disable the calibration such that the sensor only uses the already loaded profile ? - At different time or in slighly different environmental conditions, the warm-start does not make the accuracy to initialize to 3. However, we are no longer able to perform another round of proper 6 orientation calibration. How much error on Roll/Pitch we should tolerate in these conditions? - As mentioned in the application note "bst-bhi260_bhi360-an002.pdf", Roll/Pitch Dynamic accuracy is max 10deg when the sensor is well calibrated. Is there quantitative performance indicator like that for other accuracy levels?  ...

Hi JAS, We did not find any solution for that, and gave up! It is bad that BHI360 also has that issue!!! ... View more

In the Development Desktop 2.0, after uploading the "Bosch_APP30_SHUTTLE_BHI260_BMP390.fw" firmware, in the "General Settings" window there is a tab called "Virtual Sensor" where all available virtual sensors are listed. I can see all IMU virtual sensors (Acc, gyro, GRV, ...) and pressure, but no virtual sensor for temperature data. Temperature data shows up in the list if I upload "Bosch_APP30_SHUTTLE_BHI260_BME68x.fw" firmware instead, however, BMP390 itself is a pressure/temperature sensor and I expected the BHI260AP+BMP390 firmware support that as well ...
