Wake application

Once again, I ask my question...

 

I've got an application which reacts on push made by server...

 

After few minutes, the "lock" screen is displayed (it's a image in my situation).

 

If I send a notification (like the push notification sample), the sound my app does play is well heard but the screen remains

on the lock screen.. So I MUST press home button to see what has been displayed on the screen.

 

Question : How a html file through asl.js or anything else can wake up the sb1 to act as if the user has pressed the home button ?

 

thanks
