I have an app running WM5 PPC (Cingular 8125).
The app is a client that needs to send periodic heartbeat messages to its
server. When the device enters into the hibernate mode the Form.Timer does
not seem to work, because I cannot see the heartbeat being sent (maybe the
timer works, but the 'OnHeartbetTimeout' cannot run). Is there a way to make
it work (preferably without waking the whole device - no need for UI at this
point)?
What I have also seen is that when the device receives a message from the
server, it is able to respond (send a TCP message back), without being
explicitly woken up (no use of 'SetSystemPowerState'). How does that work?
Can I mimic this behavior?
