Bluetooth

hi all

i am trying to develop some application for bluetooth in j2me, and for this i have studied protocols. i have some queries related to OBEX...

1. In connect request format what does "flags" and "max. object packet lenght" actually indicates?
2. In disconnection request format what does "packet lenght" indicates? Is it the lenght of payload or is it of request packet length?
3. what does the "sequence of headers" indicates? are these payload headers?
4. suppose if we want to send a perticular file then how actually it will be sent? will it go with the "put" and "get" packet format or with something else?
5. how TCP/IP depands on OBEX?

i am refering "bluetooth specifications" for this.

please help me out... any help is appriciable....
