Issue with the Obex target header

Hi,

We are developing a Bluetooth application where we need to use a custom
service extension, instead of the default [Inbox/ Folder browsing] services.
So we tried to add a user defined target ID (in the obex header). We have
added the registry for the new Target ID (GUID)


We found that the IObexDevice Connect fails when we use, user defined target
ID, with an error OBEX_E_CONNECTION_NOT_ACCEPTED .
At the same time it works well with the standard GUID (eg,
CLSID_FileExchange_NetOrder ), when we use standard GUID our service is
getting executed.
Why it is not working with the user defined Target ID?
Is there any other steps to activate the new target ID other than the
registry entry under the HKLM,Software\Micosoft\Obex\Services ?

Thanks,
Jinesh
