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."

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.

Re:

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 [bbc.co.uk] guy, who's doing it himself. Yes, I'm not a nuclear physicist.

Re:

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 [wikipedia.org] and the related optoelectric nuclear batteries [wikipedia.org]. You can also get lights that'll last for about a decade. [wikipedia.org]

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?

Re:

[TheRaven64]

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.

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?

Re:

[Mr. Freeman]

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.

Bluetooth 3.0?

[metalmaster]

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

Re:Bluetooth 3.0?

[WrongSizeGlass]

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

Re:

[hitmark]

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

Re:

[cduffy]

Great, all those earpiece douchebags can talk longer and louder, and Minivan Mommie can swerve around in traffic even longer.

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.

Re:Low-power douchebaggery?

[DJRumpy]

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.

Re:

[Another, completely]

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

Re:

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?

Re:

[Another, completely]

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

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.

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 [zigbee.org], 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 Bluetoo

Will this promote tech waste?

[Irick]

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.

Re:

[cduffy]

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!

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.

Re:

[thijsh]

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.

Re:

[hitmark]

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

Re:

[thijsh]

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.

Bluetooth / WiFi incompatibilities

[stavrica]

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.

Re:

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.

Re:

[hitmark]

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.

heart rate and power

[johnjones]

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 ?

Re:

[fuzzyfuzzyfungus]

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
