Bluetooth 4.0 Spec Adopted

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."

    Did i miss something? The last i've heard of anything bluetooth was 2.2EDR

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

    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...

    Warp engines would be good too. So would StarGates, food replicators, and holodecks.

    Holodecks? Are you insane? Do you even remember how many problems the damn thing caused on Startrek?

    This bit from TFA links has me a bit worried. With the mobility of these devices compared to WiFi, which is relatively non-mobile, what sort of walking interference (Bluetooth vs. WiFi) can we expect from 4.0 devices?

    Moreover, an increased modulation index has actually increased the effective range from 30 feet or so, to beyond 200 feet.

    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 want nuclear fusion that can fit in my pocket. That, combined with my Quasimodo-esque looks, will almost certainly guarantee that I never reproduce (which could only result further degradation of the planet's gene pool) ;-)

    You can get nuclear fission that'll fit in your pocket now, and safely generate electricity.

    Look up betavoltaics and the related optoelectric nuclear batteries. You can also get lights that'll last for about a decade.

    All of those can be miniaturised, and use a radiation source that only emits beta particles, which won't penetrate through the case, so you won't have to sacrifice your looks for convenience.

    Isn't science awesome?

    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/professionals only(if, probably, more transparent than they would like to anybody with hardware hacking chops and some guts).

    If one is lucky, they would probably make mostly-standard use of the bluetooth serial profile, the way that bluetooth GPSes do, with some additional commands tacked on to allow for configuration, and (ideally) to make the device spit out a nicely formatted description of exactly what information it is providing.
