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
Great, all those earpiece douchebags can talk longer and louder, and Minivan Mommie can swerve around in traffic even longer.
I want to delete my account but Slashdot doesn't allow it.
Good, Bluetooth has been known to consume a lot of power. I hope this allows it to replace zigbee. Zigbee has outrageous licensing fees. It costs thousands of dollars to implement.
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.
Yes, "they" should drop whatever disparate projects "they" are working on and unite as one to accomodate your priorities. Because after all, there's no way to work on both problems at once.
I would imagine table-top nuclear fusion would be in your best interest also. But since "they" are ultimately the ones who get all the cash, it's only fair "they" do the job. Unlike this guy, who's doing it himself. Yes, I'm not a nuclear physicist.
It's a new competitor to bluetooth published by the wifi alliance.
It looks pretty cool, but so far I haven't been able to lay my hands on a copy of the spec.
Broadcom said at MWC they were publishing a bunch, but a search on their website brings up zilch.
If any helpful slashdotters have it, a copy emailed to ricosec@yahoo.com would be greatly
appreciated.
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) ;-)
Since you're not a nuclear physicist, have you possibly thought that nobody actually knows how to make an economical fusion reactor? Have you also thought even though fusion power would be good, that doesn't mean that it is inevitable or even possible?
Warp engines would be good too. So would StarGates, food replicators, and holodecks.
Nope, of course you haven't thought about the scientific and technical issues. That would require understanding nuclear fusion. Instead you just make a conspiracy theory. Well done sir. You've earned your mod points.
Holodecks? Are you insane? Do you even remember how many problems the damn thing caused on Startrek?
That's because they were beta tech, duh...
Don't worry. Had you said this about Christianity you would have been modded +1 Insightful.
You've never been to one of Quark's holosuites have you?
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.
(more info here: Wi-Fi and Bluetooth Coexistence)
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 ?

Yeah, but fusion IS possible. It's real science, none of this "OMG I CAN GET PERPETUAL MOTION!!!!ONEONE!!" nonsense. Fusion just has a bunch of problems that will be solved as technology progresses, there's no underlying concept that dooms it. It's a lot of "we don't have magnets that are more efficient" or "we can't contain a plasma stream of such a high temperature", things that are solved with new materials given some time.
-1 disagree is not a modifier for a reason. -1 troll, flaimbait, redundant, overrated are NOT acceptable substitutes.
Eh? If you want to use ZigBee in your wireless gizmo, you buy a ZigBee module just like you buy a Bluetooth module, and put it in.
If you want to sell ZigBee modules that you make yourself, your company joins the ZigBee Alliance for $3500/year, a trivial amount if you're paying yourself a salary (and if you're serious about compliance to the specification and using the ZigBee logo in your advertising).
If you want to sell someone else's ZigBee modules, you don't pay anything.
These are all similar to Bluetooth, except that the lowest membership grade in the Bluetooth SIG is $7500/year.

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?
But since "they" are ultimately the ones who get all the cash, it's only fair "they" do the job. Unlike this [bbc.co.uk] guy, who's doing it himself.
Next you'll link to some guy playing with lasers, and claim he's building a death-star.
I was hoping to see them establish a Power over BlueTooth in the standard but I guess we have to wait for 5?
I work for the Department of Redundancy Department.
cf. Dilbert on asking users to help define product requirements:
User: I want free nuclear power that won't mutate me. Unless the mutation gives me x-ray vision.
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.
is that you?
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
Betavoltaics are not fission, they are radioactive decay. Fission is when one dense nucleus splits into smaller ones. Fusion is when two smaller ones combine to form another one. Decay is when one transmutes into another form, emitting radiation. In the case of betavoltaics, you have a neutron decaying into a proton and an electron (beta particle), and a neutrino that you can safely ignore. The electron is captured to generate power. No fission required.
