NavEKF not running? No output from EKF1,EKF2,EKF3,EKF4


We are currently developing camera tracking and fault tolerance on a quadrotor for a Master thesis . We are using a PX4 and have Arducopter v3.2.1 installed on it. We followed the guide about how to enable the NavEKF by setting AHRS_EKF_USE = 1, however when we log data and try to visualize the outputs from EKF1-4 all the values are zero. There are IMU, MAG and even ATT data to visualize and they make sense. Has anyone else experienced this problem? And is the NavEKF really enabled when setting AHRS_EKF_USE = 1? Also which code from the library is running the NavEKF , is it the AP_NavEKF or AP_AHRS_NavEKF?

Thanks in advance,

Did you find a solution to this? Im trying to log wind speeds
