Thank you for the confirmation.I am however having issues getting the accelerometer readings to report reliably. I had to make some minor changes to get the basic.ino example to compile: 1) LITTLE_ENDIAN redefined. This board uses a NRF52840 with a toolchain that already defines LITTLE_ENDIAN. I replaced LITTLE_ENDIAN (and BIG_ENDIAN) in the BoschSensorHub to BHY_LITTLE_ENDIAN (BHY_BIG_ENDIAN). 2) BHYSensor::pageSelect missing return statement. If the device fails to return an error or ack (matching parameter) in the parameter acknowledge register within 250 milliseconds the function reaches an undefined return. I added a BHY_E_PAGE_SELECT_TIMEOUT error for this state. The changes can be found here: https://github.com/braingram/BoschSensorHub/commit/2c3cdd8dd3624a26cd80144f99156acddb23a301 With these changes the basic.ino compiled and loaded with no issues. I modified orientation.ino to attempt to read the accelerometer (file found here: https://github.com/braingram/BoschSensorHub/blob/master/examples/accel/accel.ino). This code compiles and runs however I've encountered 2 different problems (with different boards). Some boards report: ``` Serial working setup... Sensor found over I2C! Product ID: 0x83 Uploading Firmware. Firmware booted Orientation callback installed Failed to enable virtual sensor (Accelerometer (Non Wake-up)). Loaded firmware may not support requested sensor id. All ok ``` Others successfully read a few dozen accelerometer readings and then suddenly stops with no reported error. ``` Serial working setup... Sensor found over I2C!

VDD_nRF is 3.3 volts and the same supply that powers the NRF52840. There are a few other devices on the i2c bus (MMC5633 and MCP7940). Thanks again for your help and any advice is greatly appreciated.
