obex specifications

TracNav

The obex specifications from  http://irda.org/ are not redistributable any longer. And  http://bluetooth.org/ is members only now. There are some documents available at  http://bluetooth.com/Bluetooth/Learn/Technology/Specifications/ though.

The Object Exchange (OBEX) protocol is outlined and information on the following interesting profiles is given:

  • Generic Object Exchange Profile (GOEP)
  • Object Push Profile (OPP)
  • File Transfer Profile (FTP)
  • Synchronization Profile (SYNCH)
  • Basic Imaging Profile (BIP)
  • Basic Printing Profile (BPP)

Debugging

If you want to report problems please enable debugging output with OpenOBEX and ObexFTP.

General debugging instructions

Remove any old installation of OpenOBEX and ObexFTP, first. Then get a fresh download of OpenOBEX and unpack it. Run a configure, make and install now: 

  CFLAGS="-DOBEX_DEBUG=4 -DOBEX_DUMP=2" ./configure
  make clean ; make ; make install

For obexftp it's 

  CFLAGS="-DOBEXFTP_DEBUG=5" ./configure
  make clean ; make ; make install

OpenOBEX uses debug levels 1-4 and additional dump levels 1 (tx only) and 2 (tx + rx). ObexFTP uses debug levels 1-5 where level 5 enables packet dumping.

Gentoo debugging instructions

  CFLAGS="-DOBEX_DEBUG=5 -DOBEX_DUMP=1" emerge openobex
  CFLAGS="-DOBEXFTP_DEBUG=5" emerge obexftp

RPM-based debugging instructions

Can someone please post instructions how to run a RPM-based rebuild with the above CFLAGS?

Creating/submitting a patch

Please diff against current svn trunk. Check-out the source: 

svn co http://dev.zuckschwerdt.org/svn/openobex/trunk /tmp/openobex

Apply your changes to the source tree at /tmp/openobex. Create the patch: 

svn diff /tmp/openobex

Paste the output into a file (or redirect the svn diff output), then create a ticket and attach the patch.
