OBEX Registry Settings (Compact 2013)

3/26/2014

The registry stores information that is required to configure the system for applications and hardware devices. The registry also contains information that the OS continually references during operation.

Note

The default registry values vary depending on which catalog items are included in your OS design

You can change the registry settings for the Object Exchange (OBEX) Protocol server extensions. The registry key is HKEY_LOCAL_MACHINE\Software\Microsoft\OBEX\Services. The key can include one of the following subkeys:

  • UUID
  • String name
  • Set of hexadecimal digits

There is a subkey for each exported service. A subkey must evaluate to a TARGETID field in the OBEX request packet. For more information about OBEX requests, see the OBEX documentation under "Object Exchange Protocol" in the MSDN library.

The registry key can also contain the value for BluetoothSdpRecord, which is sent to Service Discovery Protocol (SDP) for OBEX. The OBEX server provides a channel ID for the record, registers it at startup, and unregisters it at shutdown.

You can change the registry settings for the OBEX server configuration parameters. The registry key is HKEY_LOCAL_MACHINE\Software\Microsoft\OBEX.

The following table shows the registry values.
