Re: Bluetooth Mouse Keeping User Activity Alive?

Tech-Archive recommends: Fix windows errors by optimizing your registry

Well, my attempts to quickly build an OS for Mainstone that will duplicate
this have failed. Sorry about that. I think the first thing that I'd try is
use the display settings (backlight control), to try to see if the user
activity timer is getting strobed, either because there's actually a
mouse_event() being sent all the time (or every polling interval of the
Bluetooth device). If not, my best guess is that the connected/polled
device is responsible and you should check your USB host driver, if that's
how the Bluetooth communications are handled (or via whatever method it *is*
handled, if not USB). I don't see any sign that the Bluetooth drivers or
the HID profile themselves would keep the device from suspending when the
mouse was not moved...

Hmmm. Didn't make any comments that would have offended me, if I'd been
the recipient. Sorry.

How is Bluetooth implemented on this device? It's a USB dongle? Wired to
a serial port on the processor or something like that? If the former, you
should verify that USB activity doesn't cause the system to be kept awake
(check your USB host driver for signs that active USB devices force the
system power state to some setting or higher). I don't see anything in
the HID device portion of things that prevents the system from sleeping
when a Bluetooth HID device is connected, but I'm still looking. If you
have a DEBUG build, you might set a breakpoint near line 602 of
mouhid.cpp, \public\common\oak\drivers\usb\class\hid\clients\mouhid\base,
and see if that's being continuously sent, whether the mouse is moving or
not.

I agree that I didn't put too much information but I doubt it was required
to be offensive about it.

Anyway, I am compiling CE 5.0 for ARMV4i with all QFE's until august 08
incl. I am not using any special mouse or bluetooth drivers (version 2
of the stack). I use the one present in CE 5.0. The mouse is Microsoft
Wireless Lasermouse 8000.

Now as for the way to reproduce the behavior is quite simple, only bind
your mouse with your device and let it be. I would expect that the
device will go in suspend after a while since no one is moving the mouse
but it doesn't. And that's why I am asking the question...

We can't tell you. You're the only one that knows *anything* about this
mouse (what have you told us? It's a mouse; it connects via Bluetooth;
not much!) It could be that the mouse is constantly sending 'mouse
move' messages. It could be that the driver for the mouse, which we
can't identify since you didn't tell us anything about it (it's using
the Windows CE driver that comes with the OS), is forcing the system
power state to be something other than idle. We don't even know what
version of Windows CE you're talking about!

Hello All,

I have noticed since I am using a bluetooth mouse with my device that
it doesn't go in to user idle or sleep power save mode anymore. Is it
a normal behavior or I must setup something in order to get it work
like other peripherals regarding power saving modes.

Thank you,

Keaven
