LSM6DS3 activity/inactivity recognition: restore activity by software

[Roberto Preghenella]

Dear all,

I'm working on a LSM6DS3 chip.

I have configured it to exploit the Activity/Inactivity recognition functionalities, and all is working.

On the other hand, I'm not able to do the following and/or to find documentation references for that.

The chip recovers

from the Inactivity state to the fully Active state if I shake it or tap it, which is fine.

 

But I would like to restore the fully Active state by software, without the need of physically touching the sensor.

Is there any way this can be achieved?

I tried resetting registers, re-configuring and so on, but this seems not to be working.

Thanks for help and hints.

Cheers,

Roberto

You should be able to switch from inactivity to activity mode by writing:

• WAKE_DUR = 0 in register WAKE_UP_DUR (5Ch)
• WK_THS = 0 in register WAKE_UP_THS (5Bh)
