am working on a BT app on CE 5 and need the functionality of BthSetMode. In particular my app needs to be able to:1. enable/disable discoverability2. enable/disable connectability3. power down BT to save battery lifeI have scrounged through the source on CE 5 and 6 with no luck. I have also looked through the registry in hopes of finding flags that could be set (no luck). Also none of the socket options look any good for this functionality. I thought of unloading the BT stack dlls but that seems extreme to me plus I am concerned about the side effects.Any ideas on this would be appreciated
解答：
While BTD is registered as a CE Service and you may you the IOCTL_SERVICE_START and IOCTL_SERVICE_STOP to enable and disabled the BT stack. A samples could be found in $(_WINCEROOT)/public/common/oak/drivers/bluetooth/SAMPLE/BTLOADER/btloader.cxx For the Discoverability could be set via BthWriteScanEnableMask API and more sample could be found in $(_WINCEROOT)/public/common/oak/drivers/bluetooth/SAMPLE/BTCP/btcp.cxx
