Re: [1/11] bridge - handle delete of multiple devices with same address

Great work Stephen, just tested with Bluetooth PAN and everything works now. For the bluetooth people, here is the bk link to the patch: http://linux.bkbits.net:8080/linux-2.5/cset@40afb9c8_3WOgNFCBlahWsksS_5icQ?nav=index.html|ChangeSet@-3d Thanks to all the people that helped me.

Announce : BlueZ-based implemantation of JSR82

Hi, We have developped a JSR-82 implementation for Linux, which is based on BlueZ and which is compatible with most USB-Dongle's. We've used parts of JavaBluetooth.org's works and parts of JBluez's stuff. The native C-Code of the project is entirely based on the BlueZ project and I would like to thanks Marcel Holtmann for his answers to my questions, which were all helpfull. We've decided to make the Linux version OpenSource. The JSR-82 specification is not yet fully implemented but the major part of the work (let say 95%) is done. The package can be downloaded at the following address: http://www.avetana-gmbh.de/avetana-gmbh/jsr82.xml The web site is in german but will be soon translated in english. JSR-82 is a Sun Microsystems specification for easily developping bluetooth based application in Java. Good tutorials can be found on the Java developper Center web site as well as on manay other web sites. For more information about JSR-82, please consult the site: http://www.jcp.org/en/jsr/detail?id=82 Julien Campana, ------------- Avetana GmbH Julien Campana - CTO Beiertheimer Allee 58 D-76137 Karlsruhe E-mail: julien.campana@xxxxxxxxxx Web: http://www.avetana.de ------------------------------------------------------- This SF.Net email is sponsored by: Oracle 10g Get certified on the hottest thing ever to hit the market...

Re: Bluetooth, Mobile IPv6 and PAN profile

Hi Haiguang, > Has anybody tried to test the Mobile IPv6 over bluetooth with PAN profile? > > For example, two node work as NAP with bluetooth and one node as PANU. > > If you did, please give me some hint? > > Now I am trying on the stuffs. I've never done this nor have I tested IPv6 together with PAN, but the BNEP is only an ethernet emulation and so everything that's working over ethernet should work over BNEP, too.
