Thanks for you all helped me all the way in this week, now I have successfully set up a bluetooth LAN access server (on FreeBSD 5.2), I send everybody a bluetooth usb dodges. MAC OS notebook works fine, Windows 2000 dials in with no problem, my FreeBSD notebook works great. Each computer access desktop computers in the LAN no problem, surf the Internet etc. A Linux user is still fighting his way dialing in, but I think he will figure it out very soon. It's the finest day, the sun is shining and we have bluetooth LAN... Thank you everyone who helped me! On my configuration I setup LAN access server listen to channel 1, and everyone dials in on that channel. I'm not sure of the concept of "channels", sometimes when other people are connected, I use "rfcomm_pppd -c -C LAN -l bluetooth-client" and get "no socket available" prompt, then I use "rfcomm_pppd -c -C 1 -l bluetooth-client" and it works. Sometimes (not very frequently) iBook disconnects and cannot connect anymore unless the bluetooth ppp server restart. (Windows notebook no problem.) Is it because we are sharing channel No.1? Should I register LAN service on channel one through channel six? Please give more advices. When the network work fine and I figured out all the problems, I'll write a guide on my homepage. I hope it can be useful thanks to my mixed OS environment. and I hope you can correct my article by then:) _________________________________________________________________ 与联机的朋友进行交流，请使用 MSN Messenger: http://messenger.msn.com/cn From owner-freebsd-bluetooth@FreeBSD.ORG Tue Mar 2 11:54:30 2004 Return-Path: Delivered-To: freebsd-bluetooth@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 91B9A16A4CE for ; Tue, 2 Mar 2004 11:54:30 -0800 (PST) Received: from web40310.mail.yahoo.com (web40310.mail.yahoo.com [66.218.78.89]) by mx1.FreeBSD.org (Postfix) with SMTP id 7E70D43D1D for ; Tue, 2 Mar 2004 11:54:30 -0800 (PST) (envelope-from m_evmenkin@yahoo.com) Message-ID: <20040302195430.58891.qmail@web40310.mail.yahoo.com> Received: from [66.35.239.94] by web40310.mail.yahoo.com via HTTP; Tue, 02 Mar 2004 11:54:30 PST Date: Tue, 2 Mar 2004 11:54:30 -0800 (PST) From: Maksim Yevmenkin To: freebsd-bluetooth@freebsd.org, Zhang Weiwu In-Reply-To: <4044CFB1.90607@cw.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Subject: Re: bluetooth channels -- not very clear on concept X-BeenThere: freebsd-bluetooth@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: Using Bluetooth in FreeBSD environments List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 02 Mar 2004 19:54:30 -0000 Hello, [...] > On my configuration I setup LAN access server listen to channel 1, and > everyone dials in on that channel. I'm not sure of the concept of > "channels", in your case these are RFCOMM channels. a single RFCOMM channel represents a logical connection between two devices using RFCOMM procotol. think of it as a virtual serial cable. you can have up to 62 RFCOMM channels between *the same* pair of devices. if you simplify the picture enough you might find it similar to IP:PORT concept, where IP is a BD_ADDR of the device and PORT is a RFCOMM channel. note: this analogy is not quite correct because there is a L2CAP layer between baseband and RFCOMM. the RFCOMM server is listening on wildcard BD_ADDR (*) and RFCOMM channel 1. so when new connection is accepted from the remote device will spawn new daemon to service the connection and run PPP over it, i.e. *:1 - LISTEN -- main server BD_ADDR_LOCAL:1 <-> BD_ADDR_REMOTE1:1 -- client (1) BD_ADDR_LOCAL:1 <-> BD_ADDR_REMOTE2:1 -- client (2) becase BD_ADDR of the remote device is different you can share the same RFCOMM channel between serval devices. > sometimes when other people are connected, I use "rfcomm_pppd > -c -C LAN -l bluetooth-client" and get "no socket available" prompt, then I > use "rfcomm_pppd -c -C 1 -l bluetooth-client" and it works. hmmm... is that the exact command you using? in client mode (-c) you need to specify the address of the server to connect to (-a) otherwise it will not work. also what does "no socket available" is that the error you are getting? > Sometimes (not very frequently) iBook disconnects and cannot connect > anymore unless the > bluetooth ppp server restart. (Windows notebook no problem.) Is it because that is strange. i'd like to take a look at hcidump output. you will need to download it from http://www.geocities.com/m_evmenkin/ > we are sharing channel No.1? Should I register LAN service on channel one > through channel six? if you only have one bluetooth device attached to the server then you should be fine. you need to register mulitple RFCOMM channels only if you are running multiple RFCOMM servers. you can do it if you have more the one bluetooth device attached to the server. again, keep in mind that a single bluetooth device can only have 8 clients at a time. thanks, max __________________________________ Do you Yahoo!?

They recognize LAN and > connect to channel 1. Linux user always gets refused. (so strange the Linux > bluetooth LAN tool pand(1) don't have a parameter to specify what channel > to connect to.) well, think about it :) how would MAC OS and Windows would know which RFCOMM channel to use? the only way to find out is to send SDP query to the server and ask if the server provides LAN service. so both MAC OS and Windows *do* ask for RFCOMM channel number. Linux tools do the same. it seems that you have the same problem on FreeBSD and Linux when you try to use SDP. > > > Sometimes (not very frequently) iBook disconnects and cannot connect > > > anymore unless the > > > bluetooth ppp server restart.

BTW Linux users should have hcidump tool. it should be compatible with the one from FreeBSD. it would be nice to have Linux dump as well. > Today the iBook problem is (I guess) solved.

We will sortly start some development on developing some bt hid devices and I'm looking to setup a unix workstation of some kind for it. Is there good enough support in FreeBSD 5.x for a bt keyboard or should I use a linux workstation for now. Also, it seems that just about all bt usb dongles use the same protocol looking through the linux bt usb database where they all use the same driver, though some need firmware installed. Is there a good chance then that if linux supports a specific dongle without any firmware requirements with the generic driver that it will work on FreeBSD as Linux's tested hw list is much greater and we've already purchased a belkin adapter. --=20 I sense much NT in you.
