Opening L2CAP PSM channels

Hi All,

I have spent a number of days working with the bluetooth stack on the
Mac OSX. Its been particularly hard because the packet-decoder is not
available.

My issue is that while i can open any RFCOMM channel I want. I have
trouble with L2CAP. My application is a modification of the sample
Server RFCOMM program twisted to open connections with L2CAP. I simply
wanted to experiment working with L2CAP.

I can open an L2CAP channel with PSM on 1 & 3, but all others fail with
a 0xe00002cd error. (This is from either Obj_C or C++). The error is
described as
#define kIOReturnNotOpen iokit_common_err(0x2cd) // device not
open

However, I have a device open command preceding the call. Another issue
is that the client (or the server application) does not even notice a
notification request.

The only problem I can think of is something is some how blocking all
access on ports other then 1 & 3.

Does any one have any experience with this problem? Is there something
I am missing?

General structure of the app.
Setup the server.
Define an SPD
Start the server.
Define the listening notification

Start client.
Connect to server.
See failure.

Rinse repeat.

And Happy Holidays all!

Alex
