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).
