Hi, BNO055 pin-10 is a debug pin which indicates Boot loader mode. It goes high once the boot loader becomes active. BNO055 keeps the output state of pin-10 at signal ground after the boot loader mode exits and the application code of BNO055 starts. Thanks. ... View more

Thank you for your reply; I am not designing my own PCB; I am using a breakout board (BNO055 9 DOF intelligent version: https://www.dfrobot.com/product-2142.html).  The attached plot can give a clear insight into the drift when I try to use the indoor sensor. For the way it has been programmed through its library, I used the NDOF mode and accessed the readily converted quotations by the built-in algorithms to calculate the knee angles.   ... View more

Hi, Thanks for your inquiry. You may refer to the Arduino sample code on the Github at https://github.com/bolderflight/bmi088-arduino.  Thanks. ... View more

Thanks for the input @hqlsolution  It sounds like you are saying that I could configure undersampling in both modes, while @FAE_CA1 just stated that "When BMI160 accel is in LPM, acc_us bit must be set to 0b1. When BMI160 accel is in normal mode, this bit must be set to 0b0.".  Thus I am a bit torn - would either of you care to elaborate? ... View more

Hi, Thanks for your inquiry. BMP581 operating pressure range is 0.3bar to 1.25bar. It will work at 0.15bar and 1.5bar without getting damaged. However, the performance will not be guaranteed. You will need to characterize and calibrate BMP581 outside of the range. Someone outside of Bosch has successfully used BMP581 in high altitude balloon project. The same applies to BMP585 waterproof pressure sensor. The maximum rating for BMP581 and BMP585 is 20bar. If the pressure goes higher than 20bar, then BMP581 and BMP585 may get damaged. Thanks. ...
