Bluetooth for Linux Released

Bjorn Wesen writes, "A GPL'ed Bluetooth driver for Linux has been released by Axis Communications, supporting the current Bluetooth LAN-profile (PPP over Bluetooth). The download and mailing lists are at their developer site. This will become useful especially for embedded/mobile Linux devices - and to push Linux into the new technology before The Other OS. " Bluetooth has been getting a /huge/ amount of attention from the technical press, as well as the mainstream press. It looks to be one of the most promising standards for short-length wireless communication devices and drivers for Linux is a good thing to get this early in the game.

      Basically, (the Intel page doesn't say this) some engineers at Ericsson thought about designing a new protocol for communication between their (Ericsson's) devices in 1994, and started developing it. The project wasn't initially called Bluetooth, but "MC link" (MC = Multi-Communicator). But somewhere during the development, they started to realize that the chips needed for this would be much cheaper if it was a widely adopted standard, so they started talking with their arch rival Nokia about sharing the technology and making it a common standard. They formed a Special Interest Group (SIG) in 1998, together with some other well-known companies (amongst others IBM, Intel, Motorola, 3Com, Casio, Cirrus Logic, TDK, Compaq, Dell, Xircom, Lucent, Toshiba, Psion, Qualcomm and Axis).
      Last year they released the specification for version 1.0 of the standard. And experimental Bluetooth devices have been built using the standard and shown on various expos last year, and real devices are under development now. I think we'll see many of these devices released this year. That's the brief history of Bluetooth.

      No, in 802.11, you don't need an access point. The access point is usually just a bridge, so you can hook into your lan (you could do this with a linux box, a wavelan card, and an ethernet card).

    I like the concept about bluetooth: To put it simple it makes everything communicate with anything (as long as it includes the bluetooth chip and is close enough). As far as I know the basic chip communicates about 10m (30feet for you non SI people) as so many else have said already. Combined with IPv6 I suppose this can give you a network in your home with a specific IP for your fridge (if anyone would want that).
    I'm not sure about how much attention this has had in the rest of the world but here in sweden (where Ericsson, who came up with this, is from) there has been lots of talking about this lately espescially among developers of technical stuff.

  29. What bluetooth is really for by Spyky · · Score: 4

    A lot of the posts here seem to think that bluetooth is for wireless networking. From what I understand thats not entirely the idea. The range is very very short (10m) and thats under good conditions, going through walls is going to cut that range a lot. The idea as I understand it, is too replace a lot of items that currently use infrared (because this doesn't require line of sight, goes a bit farther). That means things like cell phones communicating with PDAs, laptops communicating with printers, maybe someday video game controllers communicating with base units. I can't wait for the day that I can carry my palm in my pocket and have it automatically hotsync with my pc every time I walk close. Thats bluetooth.

    Also the other benfit is that it uses a communication system similar to what cellphones use, ie, no crazy modifications of currently manufactured cell phones to make them "blue tooth" compatible, and be able to sync with your palm or whichever.

Bluetooth does not eliminate wiring costs (the units 10m apart from one another must still be wired and powered). It only reduces the costs. Unless the money saved by reducing the wiring capacity is greater than the cost of the system, Bluetooth will not succeed.

    Couple issues that need to be brought up--

    1) Compatibility with existing 2.4ghz networks(i.e. 802.11): Apparently, Bluetooth nukes Wireless LANs(source: MicroTimes, about 3 months ago). So, Rob and Jeff are sitting around at a convention, when suddenly their Zoom Air wireless link dies. Rob looks up. "Who's the moron with a bluetooth device?!?"

    2) The Resurrecting Duckling. Great paper; look around online and check it out. Talks about security issues with wireless networking. Among other things, you're now *infinitely* more susceptible to somebody "nearby"(think airport) hacking your wireless device--how are ya gonna find 'em, even if you're alerted? 10m, up to 100m with extenders...you're talking about looking for a miniscule wireless extender into a well hidden wired network. Good luck...and lets not forget that with wireless devices, draining the battery is an astonishingly effective DoS attack.

    3) Trustable functionality. 10m isn't enough for cordless phones, and I don't think it'll be enough for cordless computing. Has there been any research into the human factors involved with a wireless device that can't leave the room? If you can't trust something to work, you don't use it.

    4) Broken encryption. There's no way in hell that Bluetooth has serious encryption built into it, but you can be assured that developers will design their own protocols to assume that the hardware encryption layer will take care of all secrecy concerns. At least with 802.11, you *know* when you're shining out your password publically!

    Several points to clear up misconceptions:

    1. Bluetooth is not meant to be a wireless LAN replacement (not without a gazillion "access points", anyway.) It's intended to be a cordless "desktop area network", and RF bubble that encircles Bluetooth devices allowing them to form ad hoc connections wiht one another for both data and isochronous (e.g., voice) connections. One node you connect to may optionally act as a gateway (access point) to the "real" network, if it's connected and wants to offer that service. As a transitory, ad hoc, solution, 10m is just about the most range you'd want - any more would create problems, and personally, I think they made the bubble too big. Bluetooth isn't meant for seamless raoming wireless connections, but to facilitate connections to and between things like telephone sets (wired or wireless), PDAs, desktop computers, etc.

    2. 2.4 GHz doesn't belong to either the Bluetooth or the 802.11 guys. In the US, 2.4 is one of the ISM (Industrial, Scientific, and Medical) bands (others are at 900 MHz and 5.7 GHz.) These are for unlicensed use providing that the FCC's restrictions are met. These restrictions include accepting any interference without recourse - if you want recourse, you go for licensed spectrum! 2.4 GHz was chosen because with minor adjustments, it's available for unlicensed use in pretty much every country that matters. (And it's the only reasonably low frequency for which this is true...)

    BTW - there are lots of other perfectly legal 2.4 GHz devices which can kill your wireless LAN, so don't single out Bluetooth unfairly...
