Bluetooth 4.0 Spec Adopted 59

adeelarshad82 writes "The Bluetooth SIG announced the formal adoption of Bluetooth Core Specification Version 4.0, which begins the qualification process for new, low-power devices. Bluetooth 4.0 [zipped PDF of the spec] was formally announced in April, and added a new, ultra-low-power aspect to the short-range personal-area-network technology. According to the SIG, the new 4.0 core specification should allow devices to run on coin-cell batteries for years with a new ultra-low-power duty mode."

      It's like a leap year, only for technology ... which I think makes it technically a leap year.

      3.0 was announced a while back, and was basically about bluetooth protocol over wifi radio if both where available in the same device.

      this so you get the obex profiles and such, but with wifi speeds.

      thats one of the things i have always liked about bluetooth, the profiles. With wifi you first need to set up a hotspot or ad-hoc connection. then there is tcp/ip. And then you need to find some kind of protocol that both parties can use to share files over.

      With bluetooth its basically a case of select file, sel

    Do you think people will just throw away most of the little bluetooth devices that use this new low power spec when the battery runs out rather then going out to replace the batteries, as is so often the case with small consumer electronics like cheep watches? Maybe this will promote planned obsolescence in those sort of accessory devices.

      I don't throw out my bicycle's speed and cadence sensors or my heartrate monitor when their batteries wear out -- sure, the battery may be $2 after a hefty markup, but the device it goes in is $30-70.

      This just makes Bluetooth a competitor in that field, rather than needing to join the "ANT Alliance" to build anything that can communicate with the wireless sensors. As someone with the occasional hobby-project idea, I'm all for that!

      With Bluetooth, you either had it or you didn't. After that, most users could give a rats rear end what the latest Bluetooth specifications are out there. If they get Bluetooth 4.0, it will be an "upgrade" when they replace their phone, buy a new car, or peripheral. Much in the same manor as cellphone camera. Meh, sure why not...

    • I will throw out my bluetooth devices as soon as they develop stereo bluetooth headphones which don't have 1,000+ ms of lag!

      Whoever designed bluetooth 2.2 must have had some strange use-cases under consideration. Next time consider the fact that people might like their sound to match their videos and games, buddy.

        Yours must be broken or just plain crap, cuz mine works just fine with most certainly under 100 ms of lag (or unnoticeable)... Any delay from pushing play on my phone to hearing audio is caused by the application, not the bluetooth A2DP connection.

          could be poor battery at either end of the connection, or something nearby producing noise in the 2.4Ghz band.

    • by thijsh ( 910751 )
      More likely the batteries will be lighter and smaller, and last a little longer... But not months or years, so I would not count on it anytime soon.
  • That's nice, but are the interference issues between WiFi and Bluetooth fixed yet?

    It would be nice to have the laptop connect to the stereo via Bluetooth while I'm lounging in the living room without cutting out while I'm watching YouTube.

    • I'm using a stereo Bluetooth headset while on my laptop using 802.11g. I'm hearing the music clear as a bell and my internet surfing is going unimpeded.
    • You're seriously citing an article from 2001? Really? Have you ever actually used WiFi or Bluetooth? Or even noticed that 802.11b (which your article talks about) was superseded a long time ago?

      In answer to your question, yes these issues were solved almost a decade ago. Yes, I have just been trolled.

        and it only really applied to devices that had both systems installed, and that would end up broadcasting at the same time.

        more often then not the fix was a driver update that made sure only one tried to broadcast at any more moment.

        heck, it would not surprise me if the problems came out of some lazy designer that attached both radios to the same antenna as they where on the same frequency anyways.

  • this is a good thing when heart rate monitors and power (electricity) monitors can communicate via bluetooth

    but they need a profile (standard way) of exporting this information i.e. ticks

    does anyone know how the "smart" power monitors can communicate and dump information ?

      Given that "smart meters" will inevitably end up being connected to billing, I wouldn't be too optimistic about there being any fully open standard for how they do their reporting. They will probably use some sort of mostly-standard transport(ie. bluetooth, wifi, TCP/IP over whatever is handy) for economic reasons and, for similar economic reasons, we might end up with some sort of "industry consensus" type standard, where the equipment is more or less interoperable; but the details are rather hush-hush/pro

    I was hoping to see them establish a Power over BlueTooth in the standard but I guess we have to wait for 5?

  • Umm...who really cares? Bueller? Bueller?

    Just bought myself a brand spanking new mobile phone - they're all still stuck on 2.1

    Anyone seen a single device that uses bluetooth 3?

    And now we're talking 4?

    Sorry - I don't care.
