Pro eye sensor didn't run automatically

[alwyuyang]

Hello, 

I am using the attached scripts to log my eye data with vive pro; however when the user is detected, I didn't get updated eye data for each timestamp. Anyone knows the reason?

The scripts were attached to the same game object. 

From left to right( a detail explanation was given in the code) : Time.time, unixTime, unity3d frame count , timestamp, frame_sequence, no_user, verbose_data.right.pupil_diameter_mm,..

where the data of yellow fonts comes from unity3d internal functions while the  red fonts come from the vive pro eye API. You can see that Vive eye keeps the same out during the loop. Why?

I attach also the output of  eye data. Thank you in advance if you could give me a hand. 

Best regards,

with 

ViveSR.Error error = SRanipal_Eye_API.GetEyeData(ref data);

I get error implying that "NOT INITIAL", what does it mean?
