Hi kriznik, Have you already looked into a "moat" to isolate the heat conducted through the PCB? Seeedstudio has a grove breakout for the BME280 that does something similar. Regards, kgoveas

Hi klcheung, There is not enough information here to understand what else you may be doing wrong, but from what I can understand, the dev_id parameter of the BMI160 device struct should contain the I2C address of the BMI160 depending on it's connections to the NRF52832, either 0x68 or 0x69. the reg_addr should not be overwritten with 0xd8. If you could share how the hardware is connected, and more code about how the NRF52832's peripherals are configured in software, I would be able to guide you here. Regards, kgoveas

Hi joshld, Is there a way to log the data that you receive from the sensor? Would it be possible to share the log of one of the BNO055 that drifts in NDoF mode. My hunch is that the magnetic field in the environment changes during this 12 hour period. The likelyhood that the heading drifts for a stationary sensor is otherwise very unlikely. Regards, kgoveas

Hi Plasmabot, Are the register values after the fix? Register 0x03 should be non-zero.

Hi Plasmabot, From a troubleshooting standpoint, - Either the internal sensor is not powered, (which you have confirmed it is) - The internal MCU cannot connect to the Gyroscope. Since the Accelerometer and Magnetometer are working I would assume that the internal SPI connections are fine, only the chip select to the Gyroscope could be an issue. In the schematic, the connections for pin 12 and 22 are not shown. Pin 12 is the SPI chip select for the Gyroscope and is advised to be left unconnected. Pin 22 is the chip select for the Accelerometer and Magnetometer. Could you confirm that this is not an issue and pin 12 is left unconnected? Additionally, what are the contents of the the 7 registers, 0x00-0x06? Regards, kgoveas
