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
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.
That's actually not the kind of problem space the ultra-low-power form of the spec is aimed at. Rather, it's a competitor to ANT -- ya know, the protocol your bicycle's speedometer uses to talk to the sensor reading the magnet on the wheel, or that the pedometer in your shoes uses to tell your watch how far you're walking.
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) ;-)
If it makes you feel better, sales of those earpieces is on the decline, and they're now considered to be a fashion faux pas in many circles. Thus, their use will probably continue to decline.
You can never go home again... but I guess you can shop there.
Holodecks? Are you insane? Do you even remember how many problems the damn thing caused on Startrek?
I have and use one, mostly in the car... but I'm anti-social, so what do I care? :p

Why do people insist on looking down at those who talk to their friends that just don't happen to be proximate?
I mean, jeez! There you go, yacking away with your homies and I can't do the same 'cause mine are not beside me?
What kind of technophobe are you?

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?
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.
Rather, it's a competitor to ANT
This is one thing I've been wondering about. What is the advantage of "low-power bluetooth" versus ANT? Will you be able to combine both "low-power" and "regular" bluetooth together on one chip so that I can use my bluetooth headphones while my bluetooth pedometer tells me how many steps I'm taking?
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.
Yes. That's the idea. The low-power uses the same set of frequencies, just in a different way. I'm not sure whether you will be able to see the data from your pedometer on the phone while you are simultaneously having a conversation using a connected headset, but significant re-use of components is certainly designed in. There will be chips (such as those designed for phones) that support low-power as well as other modes. An often-cited scenario is to receive a call on your phone, read the caller name on your watch, then pick up the call with your headset; and your watch should still give wristwatch-like battery life.
I expect the ultra-low-power messages to be so rare (small packets with long, asynchronous delays between) that you won't see significant interference from that. When they are not sending, they have no signal; when they are sending, they don't send much. That's how they save power. "Classic" Bluetooth uses adaptive hopping to avoid interference with local wireless signals by dropping channels from the sequence if they show unusually high error rates. You shouldn't have a problem using it next to a WiFi device.
is that you?
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
Motorola (and a few other manufactures, I'm sure) sell a great speakerphone system that clips to the sunvisor in your car, and can be wired into the vehicle's power system.
moox. for a new generation.
Remember:
1 pedometer = 1 meter of pedophile

"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
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.

How is it any more annoying or distracting than talking to someone who is present?
In Liberty, Rene
Well, screw them for eavesdropping, then.
Frankly, I don't buy that "study", either: are people working in call centers where they can overhear other one-sided conversations distracted by them? No.
Here's a test: would anyone be annoyed by a half-duplex bilingual conversation: one party speaking one language and the other speaking a different one? (Sometimes one comprehends better than one can speak, and their counterpart does as well in the exact opposite manner: this used to be common with English and French in some parts of Quebec, though over time it devolves into "Frenglish") I don't think so.
I think the people annoyed are because they are distracted by the novelty, more than anything else. Well, suck it up and get used to the technology. I can imagine the first television sets giving people headaches because they had to look as well as listen.
