Bluetooth low energy is a big part of the new specs

Bluetooth is one of the many technologies that many of use couldn't get through a day without using. It connects us to our phones, our cars, and a myriad of other devices we use for entertainment and work. The Bluetooth SIG has announced the release of Bluetooth Core Specification 4.0 and an enhancement to the specification called Bluetooth low energy is also part of the package.

Bluetooth low energy will allow a myriad of devices that were previously unable to utilize Bluetooth to take advantage of the specifications and connectivity it offers. Bluetooth low energy will be ideal for markets like healthcare, sport and fitness, security, and home entertainment. The Bluetooth SIG claims that devices using Bluetooth low energy can last for years with power from common coin-cell batteries.

“With today’s announcement the race is on for product designers to be the first to market,” said Michael Foley, Ph.D., executive director, Bluetooth SIG. “Bluetooth low energy modules for all sorts of new products may now be qualified – this is an important step towards our goal of enabling new markets with Bluetooth wireless technology. For example, the Continua Health Alliance has already selected Bluetooth low energy technology as a transport for the next version of its guidelines.”

Hallmark features of Bluetooth low energy include ultra-low peak, average, and idle mode power consumption. Low cost is a main feature and the specification allows for multi-vendor interoperability and an enhanced range. Bluetooth low energy has a maximum range of over 100 meters.

Data transfers with the low power specification will be at 1Mbps with very short data packets of 8-octet minimum and 27-octet maximum. The specification uses adaptive frequency hopping common to all versions of Bluetooth and operates in the 2.4GHz ISM band. Latency for the spec is as low as 3ms allowing an authenticated session to be established and data sent in a tiny amount of time.

The specification is also very secure with full AES-128 encryption using CCM to encrypt and authenticate data packets. Bluetooth low energy uses 32-bit access addresses on every packet for each slave allowing billions of devices to be connected.

“Today’s news from the Bluetooth SIG is an exciting step forward for technology in mobile health and wellness devices,” said Rick Cnossen, president and board chair, Continua Health Alliance. “Our selection of Bluetooth low energy for the Continua Version Two Design Guidelines extends exciting new capabilities to manufacturers and consumers alike, as well as enabling additional use cases within the Continua ecosystem."

Bluetooth low energy allows for two types of implementation -- single-mode and dual-mode. In dual-mode, the Bluetooth low energy functionality is integrated into an existing classic Bluetooth controller. In single-mode, ideal for highly integrated and small devices, the spec uses a lightweight link layer for ultra low power idle mode operation. The new specification will usher in a new range of connected devices and Nokia is already at work on integrating the tech into products.

“Nokia has been committed to this ultra low power wireless technology since its Wibree technology development. Now we are happy to see the adoption of the Bluetooth low energy specification, which will open up new market opportunities and space to innovate for the industry. The wide manufacturer base behind Bluetooth low energy technology and the combined industry effort will result in exciting new user experiences in the mobile space,” said Markku Verkama, Director, Devices R&D Nokia.

is it just me or does bluetooth keep revising?

I mean I feel like I just got in with 2.0 not too long ago and now we are on 4

or am I just getting old and I should tell you to get off my lawn now?

well that may be but it has taken USB longer just to get to 3.0

and in the realm of graphics cards over my life we have gone from PCI to AGP to PCI express (as far as I can remember, I really dont know what was in my 386)

ISA was the standard for expansion slots for a long time, in the late 80-early 90's there was VESA and VL slots which were kind of equivalent to AGP, since they were pretty much only used for graphics cards

I had a MCA (microchannel Card) in my PS/2 386sx.

Had a VESA card in my 486.

Ahh VLB, the ISA/PCI hybrid slot :) Man that shit was a joke if you used more than one VLB card though, everything suffered.

Anyone remember the "VESA local bus" joke in the letters section of a very ancient issue of PC Format? Basically it was a photo of a london red bus with the caption "local bus". I laughed every time I looked at it ^_^

AGP had many version as has PCI-E. AGP had 1x, 2x, 4x, 8x, slots and PCI-E has 1.0 and 2.0 now. PCI-E will likely see 3.0 as well.

How about hard drives too. SCSI, IDE(ata 33/66), EIDE (ata100/133), Sata(1.5Gb/s), Sata 2(3Gb/s), Sata 3(6Gb/s), Fiber channel(4Gb/s). New specs come and go over the years and the only one to really last the test of time is SCSI though its implementations have changed a lot over the years. No more termination of cables.

Let's add ATA(PIO 1-4) and ST-506(MFM, RLL) just for good ol time sake. Back then you had to PARK your HDD heads with MFM drives.

it has been moving fast I just never paid any attention :O

No worries. You don't usually have to 'upgrade' as often, and nowadays backward compatibility is usually the norm.

What happened to Bluetooth 3.0?
By strikeback03 on 12/18/2009 11:44:11 AM , Rating: 3
Did they just skip it?

And are they doing anything to actually make the connections more reliable?

Well with greater distance I bet connectivity will be better than the current BT devices.

Really? Must've missed that part . . .

I was just getting comfortable with Bluetooth 2.0 and now they have 4.0. WTF? Did i retrograde back in time? Didn't even realize their was a Bluetooth 3.0 to begin with. I really need to get out more, I guess. - BLUEBOY

Obviously, Bluetooth feels that their adoption growth should be exponential, and to make this happen, they're marketing their standards with exponential version numbers. The next one will be Bluetooth 8.0.

What's BT 4.0 apart from low energy? The article doesn't say.

But for low energy transmissions we already have ZigBee ( )

Bluetooth 4.0 failed

"Data transfers with the low power specification will be at 1Mbps" - Much slower compared with Bluetooth 3.0 + hs!

When something better becomes adopted by major vendors.

Not to argue that there isn't anything better out there. However I do know that licensing fees, manufacture costs, and all around feasibility of using are what kill off better standards for anything. But the big thing is you gotta have money to offer deals and buy big names into your board. Once that happens others will flock. Remember Blue-Ray vs HD-DVD. Suddenly you had all these big names sign exclusive Blue-Ray deals, and before you know it, HD-DVD is dead.

I think you are missing the point of bluetooth.. its supposed to be low speed and short distance. Its good because its cheap, low energy, and exactly whats needed for voice communication. Its not like we need 1 gbps speed for cell phones
