You can check the initialization status of the Bluetooth stack by using the symbolic define BTH_NAMEDEVENT_STACK_INITED, defined in %_WINCEROOT%\Public\Common\Sdk\Inc\Bt_api.h. To open this named event, use the OpenEventfunction.

During boot time, the Bluetooth Protocol Stacktakes time to fully load and initialize.

The following example code how to open the named event, BTH_NAMEDEVENT_STACK_INITED, to check the status of the Bluetooth stack.

Copy Code 
// Make sure BT stack is up
BOOL fStackUp = FALSE;
for (int i = 0 ; i < 100 ; ++i) 
{
  HANDLE hBthStackInited = OpenEvent (EVENT_ALL_ACCESS, FALSE,
BTH_NAMEDEVENT_STACK_INITED);
  if (hBthStackInited) 
  {
	DWORD dwRes = WaitForSingleObject (hBthStackInited, INFINITE);
	CloseHandle (hBthStackInited);
	if (WAIT_OBJECT_0 == dwRes) 
	{
	fStackUp = TRUE;
	break;
}
  }
  Sleep (1000);
}
if (! fStackUp) 
{
  // Perform error handling.
}
