BHI160B can't get measurements data

[VictorT]

Hello,

I'm using a BHI160B on a custom board in order to get acceleration and rotation vector data.

I'm using firmware patch : bosch_pcb_7183_di03_bmi160-7183_di03-2-1-11824.fw.

Init works fine (checking ROM version etc).

Then the acccelerometer sensor is enabled.

After a 10 seconds delay I try to read the FIFO.

I only get timestamps and the "Initialized" meta event, and no other data is read (which are already in the FIFO before enabling the sensor).

I tried several compatible firmwares, several available sensors, VS_WAKEUP/VS_NON_WAKEUP.

I attached the application code, based on rotation_vector_example.c.

What am I missing ?

Thank you for your help.

Regards,

Victor T.

Hello VictorT,

You could refer BHI160B reference code attached and run it again.

Hello BSTRobin,

Thank you for your help.

I ported and tried the code you provided. What are the takeaways ?

Here is the log I get :

start demo_sensor

bitmap[1] = 0x0
bitmap[2] = 0x1
bitmap[3] = 0x0

bitmap[6] = 0x0
bitmap[7] = 0x0

Hello VictorT,

Based you current code, you could add virtual sensor example and get acceleration and rotation vector data.
For virtual sensor example, you could refer it from here: https://github.com/BoschSensortec/BHy1_driver_and_MCU_solution/tree/master/examples

Hello BSTRobin,

Thank you, I got it working in the meantime.
