BMI270 SPI nRF52840 DK

[Aglenn5]

Hi, I am trying to communicate with the BMI270 chip with the nRF52840 DK over SPI. I am trying to get the chip_id by performing a dummy read on device start up. However, when I perform a second read to access the chip_id, this is what I get on the SDO (MISO) line. The clock is operating at 2 MHz.

This is what my code looks like broken down into parts:

1.  IMU initialization

2. nRF CLI interface command to read chip_id

This is what my SPI initialization looks like:

And here is what my SPI transfer code looks like:

Hi Aglenn5,

You can refer attached example code on Nordic nRF52840.
