I'm playing with bmx160 and right now I'm able to read data from gyro. As a next step I wanted to use FOC to calibrate gyro values (when sensor is on the table shows me realy high values, I guess because sometimes they getting down below 0). So I did following:
1. Enabled foc for gyro 0x69 to 0b01000000
2. Send CMD start foc 0x7E with 0x03
and no matter how much I wait the status register has always foc_rdy = 0 (11011000)
This bit is always set to 0, before or after foc, doesnt matter. The only bit which is changing in status register is nvm_rdy bit.
Before starting foc I set gyro ODR and power mode to normal and I wait for 80ms to complete entering normal power mode. Did I forget about smth?
Thanks for help

Thanks for quick response!
I have gravity sensor SEN0252 connected to NUCLEO-G431KB so I guess there is no way to use the application from the pdf?

The sample code in the PDF file is low level pseudo code. You can use C code in NUCLEO-G431KB to configure BMX160 on gravity sensor SEN0252 for FOC of accel and gyro.

Ok I tested this pseudo code and still foc_rdy flag is never 1. I understand that this bit should be 1 before triggering FOC, 0 during calibration and 1 after FOC is completed, right?
