Hi,
I'm using a BMI088 on the I2C bus of an embedded board. I'm using the BOSCH's driver from Github and everything works correctly, except the call to the function `bmi08a_load_config_file` that invalidates the status of the IMU, and I must reset it.
If I remove the code relative to the function `bmi08a_load_config_file`from the examples (e.g. https://github.com/BoschSensortec/BMI08x-Sensor-API/blob/master/examples/read_sensor_data/read_senso...), I can get the data from the IMU with no problems.
I used other BOSCH's IMUs in the past and the load of the config file was a procedure explicitly documented in the datasheet, while the datasheet of the BMI088 does not speak about it.
Can someone provide me with more information?
Thank you
Walter
Hi Myzhar,
Could we know more detailed information about "the call to the function `bmi08a_load_config_file` that invalidates the status of the IMU"?
It depends on the value used for the parameter `read_write_len`. Using the default value `46` in `common.c` the IMU enters in not valid status and does not reply to the following commands.
Instead, if I set a lower value (max 16) the `bmi08a_load_config_file` function fails with error code -6, but the IMU stays in valid status and continues to reply to the following commands.
I can confirm that bmi08a_load_config_file is successful (returns 0) when using the SPI interface and a read_write_len of 32. However, I have found that use of bmi08a_load_config_file results in extremely poor accelerometer performance (as described in this post), I don't know if these issue are related - the commonality is that things go wrong when we load the config file and work fine when we don't.
I'm using the I2C interface and I cannot use a `read_write_len` value higher than 16 otherwise I get the following list of I2C errors and the IMU stops working:

What I cannot understand is why this behavior is not documented on the datasheet and only firmware code exists for it...
