Bluetooth is a short range personal area network technology which is used for transferring files, contact information, connecting hands free sets and stereo headsets to mobile phones, tablets and PCs wirelessly. Latest news, expert advice and information on money. Pensions, property and more. While generally touted as easy to set up and get working, for a variety of reasons often related to the quality of the software Bluetooth stack provided with many USB Bluetooth devices, users have often found frustration in getting things beyond just basic file transfer working. This can be because of outdated software without profile support for newer devices, or a lack of software altogether, leaving the user to rely on the operating systems default and often somewhat limited Bluetooth stack. Over the years, it has made the evolution through numerous revisions each with new benefits. The initial Bluetooth 1. Bluetooth 2. 0 bought newer modulation modes which allow for higher speed data transfer and practical battery life savings for portable devices. New pairing modes were introduced which simplified and secured pairing. Bluetooth 3. 0 bought the ability to use Bluetooth as a signalling channel to use Wi Fi as a higher speed transfer medium although this functionality is often problematic.

The dongle is clearly visible from the front and measures about 2. Thats pretty small It claims to have support for Bluetooth 4. It also supports file transfer, audio and is a Class 1 device with a 5. Typically most Class 1 devices advertise a 1. Class 2 devices with lower output power typically advertise a 1. The rear of the box extols its various features and specifications. It appears to support the majority of the Bluetooth profiles available today, through the use of the CSR Harmony Bluetooth stack. The default Windows Bluetooth stack is not this capable Included in the package is an 8cm mini CD with the drivers, the USB dongle itself and a Quick Install Guide. Please heed the instructions in the install guide Also, you will need to use the CD, so if you dont have a drive in your laptop, please copy the files off onto a USB flash drive using another computer. You will not derive the full benefit of the dongle simply just by plugging it in but it will work for basic uses, but please dont do this youll find out why later. It is supplied with CSR Harmony version 2. The software is for Windows only users of Linux will have to rely on their OSs included bluez stack. Unusually, the dongle itself has its flashing LED indicator on the bottom of the device where its not in plain view. Its not particularly bright, and will not distract you too much. The dongle protrudes about 1cm from the body of the USB port, and the antenna a printed circuit board antenna is on the extreme end of the dongle. The dongle feels quite solidly built I didnt feel confident enough to try taking it apart for fear of damaging it, so there wont be any photos of the internals unfortunately. The dongle itself has a Vendor ID of 0. A1. 2, Product ID of 0. Firmware Revision of 8. Its HCI and LMP version is 6. Its MAC address starts with 0. A 7. D, corresponding to Cyber Blue HK Ltd. It identifies itself as a CSR8. A1. 0. Installing. Getting this dongle installed is no drama in most cases if you follow the instructions carefully. Start by NOT plugging in the dongle into a USB port, however tempting that might be. The first step is to remove all previous Bluetooth stacks and driver software. This is important to prevent the previous stacks from controlling your new Bluetooth device, causing conflicts or limiting its abilities. You can achieve this by removing it via the AddRemove Programs applet inside the Control Panel. If you have IVT Bluesoleil installed, or BroadcomWidcomm Bluetooth Software installed, they should be removed along with any other Bluetooth software. Then, you can execute the set up from the disc which involves following the prompts At this point, it is best to restart your computer to ensure that the software starts up correctly, despite the wizard not requesting it. Dont be lazy do itThen, you can now plug in the USB dongle, which should be detected and result in the installation of a few devices and the appearance of a new Bluetooth icon in your task tray. It should also, after the installation, pop a balloon that tells you that your Bluetooth Device is Available. If you have Skype installed and running, it will also install a Skype plugin which allows the CSR Bluetooth software to integrate with Skype just one of the perks of a proper Bluetooth stack, as compared to the Windows default stack. You can now explore the settings within the Harmony stack and commence adding devices to your system. The settings within the Harmony stack allude to many more possibilities than offered by the default operating system Bluetooth stack, or indeed, some aftermarket ones as well including support for Bluetooth 4. This may come in extremely useful in the future as low energy devices become more popular. Unfortunately, there doesnt seem to be any supported way to update the software, aside possibly by visiting the Vendors web site in the future. As a result, when devices using newer profiles not supported by the software need to be used, you may need to upgrade or purchase a new software stack or dongle and software stack together. Performance. Pairing devices compared to using older Version 1. Secure Simple Pairing. Many newer devices display a code for you to check and accept the pairing, or pair without needing to enter any codes, making it much more painless. To initiate pairing, one must put their Bluetooth device into pairing mode before initiating a device scan either by category or all. The time out on the scan is relatively quick, so be sure to initiate pairing mode on your Bluetooth device before starting a scan. For example, to pair a headset, you would choose audiovideo device, and your device should show up in the scan shortly. Select the device, and click next, and secure simple pairing takes care of the rest. Drivers for your specific device should install automatically without trouble. If not, please see the next section. Once that succeeds, you should see a bubble indicating the connection has been established. If you have paired a headset, the Skype integration will change the audio devices for you automatically. Im glad to report no audio problems at all with this stack and the Native Union Pop Retro Bluetooth Handset. Great stuff Integration with Skype also allowed for double tapping the button to initiate a call, and single tap to hang up. I also had no trouble pairing my Jabra BT 1. Samsung Galaxy SIII and my Bluetooth Keyboard to it, although A2. DP Media Audio streaming from the SGSIII to the computer curiously refused to function even with SCMS T turned on during installation. This may be a compatibility issue. File transfers to the S3 are easily accomplished by right clicking on a file and navigating to Send To, followed by Bluetooth Device. Other than that, buttons are added into Microsoft Office as well so that you can send a file directly from the ribbons interface. Sending with the Bluetooth 4. EDR rates is about three times faster than sending with my old Bluetooth v. Download Clownfish Plugin For Teamspeak 3. To test its Low Energy radio abilities, I was able to scan for and pair with my Adonit Jot Touch and Jot Script, although as there is no profile support, the connections are not usable.
