[android-developers] Re: How to keep WiFi on and let screen go to sleep?

Maybe you should just leave the display on but set all the display pixels to black?

This should help with the power drain of the display.

Thanks.

Why do you need to keep the Wifi on?

As I explained in the OP, the Android devices are used in an industrial environment.  Specifically they are used in a factory where they are sending and receiving information to a central process control PC even when users are not interacting with the display or keyboard.

But why I want WiFi to stay on isn't really the point -  the point is that this is a feature that Android supposedly supports and I can't seem to get it to work.    Is this an Android bug or am I doing something wrong?

The devices are all Samsung Media Players (a cellphone without the phone - sort of an Android iPod) running stock-out-of-the-box Android 2.35 or 2.36.
