BMI270 FIFO length always zero

[sos]

Hi, I have successfully interface BMI270 using I2C protocol. Also I am able to load configuration file.

https://github.com/BoschSensortec/BMI270-Sensor-API

I am referring examples code from above link. I have received various activities like running, walking etc. from this example "\examples\bmi270\step_activity".

I want these two activities "ON_BICYCLE", "IN_VEHICLE". This activity recognition is provided in "bmi270_context" folder.

But I am getting this warning "Warning [1] : FIFO empty". I am referring this example file "activity_recognition".

Please help me to achieve these functionalities.

Thanks in advanced.

Hello sos,

You could refer example code from github to check if your code didn't work well, so you code couldn't run into expected part.

Other suggestion is that you could test more than 30 second. For example: from still to walking, from walking to running. But for "ON_BICYCLE", "IN_VEHICLE" recognition, I think it is not good way to move board to simulate this activity status, it is better to test by bike, by car.
