It just uses the serial profile. Could you please send me the output from 
sdptool browse with and without the feature pack connected?

The only complication I can imagine, which really shouldn't be the case, is 
that the channel for the serial profile changes.

Is it possible that the actual Bluetooth Device Address changes? In other 
words, is it possible that the serial profile needs to be accessed through the 
BDA of the feature pack? Perhaps you should send me the output of sdptool 
browse for both BDAs.

Yes, it's easy to do. Look in brl-al-bc.ktb (.ktb is used for key tables).

I'm sure there's plenty of room for improvement. Please share your ideas for 
better bindings. The current ease of access to help,learn,etc was to make them 
easy to discover for new users, but maybe that's not a good idea in the long 
run.
