c# - Can only retrieve all Services when trying to get Paired Bluetooth Devices -


i writing windows/windows phone 8.1 bluetooth app spp end user needs select paired bluetooth device use.

problem #1:

i having trouble trying paired bluetooth devices paired device. can all services on device.

note: using windows phone 8.1 device bluetooth paired windows 7 laptop

deviceinformationcollection collectionofdeviceinfo;  peerfinder.alternateidentities["bluetooth:paried"] = "";   //collectionofdeviceinfo = await deviceinformation.findallasync(rfcommdeviceservice.getdeviceselector(rfcommserviceid.serialport));  collectionofdeviceinfo = await deviceinformation.findallasync();

the findallasync() gives me services on phone, including paired bluetooth , services.

problem #2:

i don't know service need bluetooth spp. if knew service needed bluetooth filter giant list of services.

i have been looking @ bluetoothrfcommchat , bluetoothcommunicationsample msdn, not helping.

ha, got rfcommserviceid.serialport work. needed add 

<capabilities>   <m2:devicecapability name="bluetooth.rfcomm">     <m2:device id="any">       <m2:function type="name.serialport"/>     </m2:device>   </m2:devicecapability> </capabilities>

to package.appxmanifest (hint: right click->view code)

then line

collectionofdeviceinfo = await deviceinformation.findallasync(rfcommdeviceservice.getdeviceselector(rfcommserviceid.serialport));

worked great.

to solve got bluetoothrfcommchat work on windows 8.1 laptop , on winows phone 8.1 device. did need restart laptop after pairing , run app startup tile , not debugging. phone side didn't need restart , can run debugging.
