Documentation

I'm working on a Bluetooth project . I installed openobex /openobexapps on my Pc and it works.The PC makes connection with the handy and send files.But now i want to understand how it does. I 've the sdp_lib.h/sdptool.c and then hci_lib.h/hcitool.c but still don't really undertand it.
Do you have some documentation about the functions(e.g hci_inquiry(), sdp_data_alloc(),..) used in those tool-files and what the really do ?Wich parameters they exactly take and give? It would be a great help for me.

I also need a documentation about obexftp and obex synchronization.
I installed teh obexftp files.but i don't really know how to use it for file management from my pc to my Bluetooth-handy and vice-versa.

Until today i can send vcards, sms and pictures to my bluetoot_handy but it does't walk vice versa-The handy can't make a connection with the PC although it automatically registered the Bluetooth-Adapter adress of the PC.Can you tell me PLeaaaaaaassseeeee how i can master that.

I hope you can help me and will be very happy to become this help.

Yours sincerely
