Bluetooth Technology Gets Faster With Bluetooth 3.0

From its annual All Hands Meeting in Tokyo this week, the Bluetooth SIG formally adopted Bluetooth Core Specification Version 3.0 + High Speed (HS), or Bluetooth 3.0. This latest iteration of the popular short-range wireless technology fulfills the consumers' need for speed while providing the same wireless Bluetooth experience – faster. Manufacturers of consumer electronics and home entertainment devices can now build their products to send large amounts of video, music and photos between devices wirelessly at speeds consumers expect.
Bluetooth 3.0 gets its speed from the 802.11 radio protocol. The inclusion of the 802.11 Protocol Adaptation Layer (PAL) provides increased throughput of data transfers at the approximate rate of 24 Mbps. In addition, mobile devices including Bluetooth 3.0 + HS will realize increased power savings due to enhanced power control built in.


"Like Ricky Bobby in Talladega Nights, this latest version was 'born to go fast,' said Mike's Blog, Ph.D., executive director of the Bluetooth SIG. "Utilizing the 802.11 radio was a natural choice as it provides efficiencies for both our members and consumers – members get more function out of the two radios they are already including in devices, and consumers with Bluetooth 3.0 + HS products will get faster exchange of information without changing how they connect. We are excited to expand the possibilities of the PAN."

This newest version of Bluetooth technology builds on the inherent qualities of the current 2.1 + EDR version, including Simple Secure Pairing and built-in, automatic security. And as with all versions of theBluetooth specification, v3.0 + HS provides developers, manufacturers and consumers with the benefit of backwards compatibility, enabling both the expansion and enhancement of this technology with every new specification release. Once products reach the market, the easiest way for consumers to learn which devices are compatible with other Bluetooth enabled devices is to visit the Bluetooth Gadget Guide.

Applications
With the availability of Bluetooth version 3.0 + HS, consumers can expect to move large data files of videos, music and photos between their own devices and the trusted devices of others, without the need for cables and wires. Some applications consumers will experience include:

• Wirelessly bulk synchronize music libraries between PC and music player or phone
• Bulk download photos to a printer or PC
• Send video files from camera or phone to computer or television

Availability

The Bluetooth SIG's formal adoption of the specification is only the first step in the product lifecycle. News out today from wireless chip manufacturers and Bluetooth SIG member companies Atheros, Broadcom and CSR shows the second step – getting silicon solutions to device manufacturers – is already underway. End products for consumers are expected to be in the market in 9 to 12 months.

Technical Specifications
This new specification release includes several major enhancements (learn more here - page requires member login):

• Generic Alternate MAC/PHY (AMP)
• 802.11 Protocol Adaptation Layer (PAL)
• Generic Test Methodology
• Enhanced Power Control
• Unicast Connectionless Data

Bluetooth USB Dongle

Ok so here's a question. I had a revelation today that: "Duh, my keyboard/mouse is bluetooth, shouldn't that be the same thing?" My goal here is to get my new Motorola HT820 bluetooth headphones to work with on my computer.

Keyboard/Mouse is Logitech MX5500 Revolution, bluetooth wireless, came with a USB dongle that they connect through. I tried today to get the headset to work, and it won't receive sound. I can get it "connected," but with complications. I'm using Windows XP, have Setpoint 4.7, and I've tried the following:

-Changed the radio settings to a bluetooth hub instead of locked to the keyboard/mouse.

-Clicked "Connect Other Devices."

- Paired headphones with windows. Windows connects correctly, the device reads connections, windows shows it as "already connected" when I try to connect it again. I click on Control Panel -> Bluetooth Devices, and I see the "Motorola HT820" listed as "Passkey enabled," but it doesn't say "Connected" like the keyboard and mouse do. Also, audio does play on the headphones.

-Click on Properties on HT820, and then on services, it does not show any services at all.

- Searched around google, logitech, motorola websites & forums to answers or help, nothing. Closet I got was logitech's "Bluetooth FAQ" which has the following paragraph (http://www.logitech.com/lang/pdf/bluetooth/bluetooth-faq.pdf):

"3.6 How do I listen to music wirelessly with a Bluetooth headphone?
All you need is a Bluetooth headphone and a media player such as iTunes or Windows Media Player 10. For optimal results, it is recommended you use a headphone with Bluetooth 2.0 Enhanced Data Rate, to benefit from the maximum bandwidth (up to 3Mb/s).
Please refer to our online "How To" documents for step-by-step instructions related to your specific device (www.logitech.com/bluetooth/howto)." [That link transfers you back to the same pdf document - it's a circle]

-I tried to install latest Widcomm stack from broadcomm's website, but it says it's not compatible with this dongle.

-Called Logitech Tech Support - got a total jerk girl who straight up said "No i can't help you." And then wouldn't give me the time of day after that.

I've read on threads on Logitech forum that people are using this headset with logitech dongles. Any help getting this connected? I just don't want to have 2 bluetooth dongles connected when I rly only should need this one. Otherwise I guess I'll just purchase one of the ones above, and use that to connect my keyboard, mouse, and headphones all in one swoop.

Sidenote: anyone have experience/knowledge with behavior when 2 bluetooth USB dongles are connected to the same computer?

 

Cannot use bluetooth device

1 Pairing is done in Settings, Devices
1.1 You click on Add Bluetooth or other device
1.2 You choose Bluetooth
1.3 If there is a pairing button on the bluetooth device itself then you press that now. You need to check the instructions for your bluetooth device to see how to do this - several automatically go into pairing mode when they switch on, others have a button that needs to be pressed for, say, 5 seconds.
1.4 The computer detects all available bluetooth devices and you select yours from the list. If yours is not on the list then Windows could not detect it.
1.5 It connects - pairing includes connecting
1.6 The computer sounds a buzz in the earpiece then displays Your device is ready to go and you click on Done
1.7 The device is shown in the devices list below the subheading Audio and it shows it as connected
1.8 The device should also appear in Control panel, Sounds, Playback tab
1.9 The device should also appear in Control panel, Devices & printers
1.10 {I just paired some bluetooth earphones as I typed so I could make sure these notes were correct} You use a music player and the sound comes out of the bluetooth earphones

2 If this is not happening for you then go to Contol panel, Devices & printers
2.1 Right-click on the device & select Remove device
2.2 You can now try pairing from scratch again
2.3 Several other users have reported that only removing the device with Bluetooth command line tools - BluetoothInstaller allowed them to re-pair again [see xzion's guidance below]
2.4 Yet others reported that only the KeithM code or Bungee's guidance worked for them [see below]

3 Where is this all going wrong for you?
[I assume we are definitely talking about bluetooth headphones/earphones. I understand that WiFi ones do also exist.]

Several people registered in TenForums just to be able to thanks xzion, KeithM & Bungee. Apparently, what worked for some people did not work for others so each solution seems worth trying.
