    clear the BHI160B fifo

    clear the BHI160B fifo

    hello. How can I clear the BHI160B fifo and not have to do all init of the device again after the device is working ?

    I have to clear the fifo sometimes when it is full with a lot of data and I don't have time to read it.

    thanks.

    Hi Eyalb,

    You can call BHI160B sensor API to flush FIFO data without reset sensor.
    bhy_set_fifo_flush(VS_FLUSH_ALL);

    hello. I tried :

    result = bhy_read_bytes_remaining(&current_transaction_size);
    /*printf ("IMU fifo %d bytes to read\n",current_transaction_size);*/
    if (current_transaction_size > 60) /* eyalb - fifo too full */
    {
    max_transaction_size = current_transaction_size;
    bhy_set_fifo_flush(VS_FLUSH_ALL);
    result = bhy_read_bytes_remaining(&current_transaction_size);
    next_transaction_size = current_transaction_size;
    }

    and next_transaction_size is equal to max_transaction_size and not zeroized.

    Hi Eyalb,

    You can send the command 0xFE and see it again.
    bhy_set_fifo_flush(0xFE);
