Bluetooth SDP - Service Discovery Protocol

The library contains support for creating, parsing, and dumping SDP records. This will generally be used in advanced scenarios only. For instance BluetoothListener by default creates a basic record based on the Service Class Id passed in.

To retrieve and dump the records containing a given UUID on a particular device one can use code like the following.

Guid uuid = ...
BluetoothDeviceInfo device = ...
ServiceRecord[] records = device.GetServiceRecords(uuid);
foreach(ServiceRecord curRecord in records) {
   ServiceRecordUtilities.Dump(curRecord, Console.Out);
For instance to see whether the device has an an Serial Port service, do a search for UUID BluetoothService.SerialPort, for OBEX Push use BluetoothService.ObexObjectPush, or too find all the services that use RFCOMM use BluetoothService.RFCommProtocol, or to find all the services, use BluetoothService.L2CapProtocol.
