No solution required.
An application can register for notification of an EDA resume by
creating a message queue using the CreateMsgQueue() API and
power notifications using the RequestPowerNotifications() API
(refer to the SMDK Help File). After an application receives a
resume notification it should close open Bluetooth sessions and
reopen them.This reestablishes the piconet lost during the
suspend.
Check the return value of APIs for errors. Look for a DCD state
change event in the Microsoft Bluetooth stack DCD window of the
Bluetooth connection.
Either wait 10 seconds, choose a different COM port number for
the virtual COM port, or modify
HKLM\software\Microsoft\bluetooth\l2cap\IdlePhys (which defines
the number of seconds to hold the connection).
