Activity detection using LSM6DS3

Hi

I'm using LSM6DS3 for activity detection.The SLEEP_STATE_IA bit of the WAKE_UP_SRC register is used to monitor the activity/inactivity,

but I have noticed that the value for the bit remains the same(ie when sleep event is detected the value of SLEEP_STATE_IA is set to 1 but even when activity is detected the value remains the same)

Can you suggest a fix for the problem? OR provide an alternative for activity detection

Can you please provide your complete sensor configuration?

Please find the sensor pseudocode in the attachments.

Other than the above-mentioned problem, I'm facing trouble with the orientation change.

When the sensor is shaken it detects an orientation change rather than activity. Please provide a solution to this problem too.

Maybe, he cannot upload detail register values.

How do you upload example full register values about the wanted operation registers (read  '1' of 

SLEEP_STATE_IA bit

 during sleep status after inactivity).

I try to set and read SLEEP_STATE_IA bit in LSM6DSL.

Successfully, read '1' of SLEEP_STATE_IA bit during  sleep status after inactivity.

but, I fail to read   '1'  of 

SLEEP_STATE_IA bit in LSM6DS3. (always read '0' of  

SLEEP_STATE_IA bit) 

(same setting values of LSM6DSL)

So, I want to know it too. how do i set in LSM6DS3 . (just want sample setting register values in 

LSM6DS3

 or STEVAL-MKI160V1 (

LSM6DS3 EV kit))
