For our tests, Globalsat provided us with the BTA-806 retail package, that came as part of Globalsat's Entertainment Pack (BTA-806, BTH-820 and BTA-830). The retail package for the BTA-806 is very small and includes the BT Dongle itself, a CD with drivers and a printed manual.

The BT dongle is very small, so small in fact, that you need to be especially careful not to lose it ;-)

2. BTA-806 Installation

The BTA-806 can be easily installed, even by inexperienced users. You only need to run setup program on the included CD.

After rebooting and installing the Bluetooth Dongle, you can access the main menu after first setting several details:

The included IVT BlueSoleil driver pack version was 2.0.0. EDR 051103

The software automatically searches for new versions. In our case it found a newer one, which was however impossible to download, since the hyperlink wasn't working...

Let's have a look at the BlueSoleil software installed on our PC and what we can do with it. At the top (see photo below), we have several icons which represent Bluetooth services, while at the center (sun) we can see our host PC and any discovered devices orbiting around it.

First off, we tried to "pair" a mobile phone (Sony Ericsson K750i).

You need to know the passkey:

Once connected, we could access the mobile's phone shared folders:

Some additional information about the K750i Bluetooth device:

In the status page, we can see the port activity as well as various other information such as signal strength:

Time to connect another device, a PDA this time (Dell Axim x50V). Again, you have to type in the passkey and "pair" the device:

We can now see some information about the Bluetooth properties of our PDA:

We next paired our BT GPS device (Haicom 406BT-C), which was connected on an unused COM port (COM6 in our case). With the appropriate GPS navigation software, you can now find your way around the world :-)

3. The BTH-820

- BTH-820

The GlobalSat BTH-820 Bluetooth Headset, is designed for wireless mobile audio devices powered with Bluetooth technology, such as mobile phones, PDAs and notebook computers. The Bluetooth Headset is small, about half the size of a credit card that also looks attractive. You can wear it on your clothes by clipping it onto a pocket or collar, or just hang it freely from a neck loop as a pendant.

The BTH-820 gives you excellent audio quality by using Bluetooth technology (supported profiles: A2DP, AVRCP, Headset, and Handsfree). It eliminates the need for a physical connection and gives you total wireless mobility at a range of up to ten metres.

It also fully supports mobile phones over Bluetooth.

For our test purposes, we received the retail package for the Bluetooth Wireless Entertainment pack, which includes the BTH-820 and BTA-830 devices, a stereo ear-bud, a spare set of headset ear-buds, a USB Y charging cable and a USB AC charger. The retail price is around US$88.

The BTH-820 device is rather small. The controls are on the front have different functions depending on the situation (incoming call or playing music).

On the left, we have the power on/off/pair button and the charge jack, protected by a rubber cover.

On the top side, there's also a 3.5" input jack for connecting any type of earphones:

Lastly, on the back, there's a clip so you can attach it to your clothing and some device information hidden underneath the clip.

4. BTH-820 Installation

- BTH-820 Installation with host PC

Using the BTH-820 with a desktop PC is very easy. In our case, we used the Globalsat BTA-806 BT Dongle. Using the BT wizard, we found the headset and "paired" it using the passkey.


- BTH-820 Installation with PDA

For our purposes, we used a Dell Axim x50V loaded with Win2003SE. We used the Bluetooth connection wizard, with the Hands-free/Headset setup and paired the device:

After pairing the BTH-820, we could only hear a contact beep, which indicated that something was wrong... Immediately we searched around the net for workaround solutions. The problem seemed to be that the installed Broadcom Bluetooth driver didn't support the Bluetooth Audio Services.

After looking at several forums, the first solution was to download Broadcom, the Bluetooth Stack Patch which had the Stereo Headphone profile from PDAGold. The installation process is easy, just move the .cab file to your PDA and double click on it. While this might solve our issues, we decided to install the 1.6 Broadcom stack. The installation is a bit tricky, we advice user to visit the AximSite and read the detailed tutorial. After we completed the upgrade procedure, we had a newer BT driver pack.

Using the BT wizard, a new profile had been created called "High Quality Audio Setup". In a few simple steps, we "paired" the BTH-820 device successfully:

The profile is also supposed, to provide control over the used media player. For our tests, we used TCMP v0.71d player for both Video and Audio playback. When playing only Audio files, the BTH-820 headset was working just fine, however when we tried to playback Video files, no sound was audible. We assumed the BT High Quality Audio Profile might work only with Audio and not Video files. Another issue we had was that the play/pause/next BTH-820 buttons didn't seem to work with the TCMP player. We searched around but couldn't find any solution, although it wasn't that great an issue for us.

- BTH-820 Installation with mobile phone

Firstly, set the BTH-820 into pairing mode (keep the power pressed for 6 seconds). After using the BT wizard on your cell phone, you will find the BTH-820 and can then pair it.

5. The BTA-830

The GlobalSat BTA-830 turns your iPod or any other portable/desktop device into a wireless music center. Using the latest innovative Bluetooth technologies, the Audio Gateway transmits digital sound to compatible Bluetooth audio receivers up to 10m away.

The BTA-830 audio kit consists of a receiver that connects to your iPod and a Bluetooth headset. It is a simple plug-and-go device which supports the standard Bluetooth A2DP profile for consistent and clear stereo sound quality.

The BTA-830 offers both digital music and mobile communications features in a portable player about the size of a pack of cards. It also gives any non-Bluetooth device the ability to work with a Bluetooth headset and enables your audio device to transfer the stereo audio signal wirelessly to the BTH-820 or any of the Bluetooth headphones.

Pairing the BTA-830 with cell phones and any audio device is a breeze. Just plug the BTA-830 into the headphone jack of your iPod, PDA, MP3, CD, mobile phone, or PC/laptop computer to listen to your favorite music through your BTH-820 or other Bluetooth Audio Device.

- Package

For our test purposes, we received the retail package for the Bluetooth Wireless Entertainment pack, which includes the BTH-820 and BTA-830 devices.

The BTA-830 device is round and available in orange or blue. On the top there is only the mini-USB jack that is used to charge the device.

Underneath, there is the power on button and the 3.5mm jack that connects to any device with an Audio Out jack.

- Installation

The BTA-830 can be installed on virtually all devices with an Audio Out jack, (e.g. minidiscs, IPods, CD players, TVs, DVD Players, Desktop PCs, PDAs, PSP, etc.). In order to pair it with the BTH-820 or any other BT Headset, you need to keep pressing the power on button for 6 seconds, when the device will blink red/blue, indicating it is in pair mode. At the same time, the BT headset should be in pair mode. Both devices will auto-pair and then you are ready to use it.

6. Performance

The BTA-806 worked perfectly with all tested devices (PDA, Mobile Phone, BT GPS devices) and since it is v2.0 compatible, it ensures compatibility with upcoming BT devices. Its small dimensions make it truly portable, the only drawback is that you have to carry the included setup disc with you, for every time you connect it to a new desktop or portable PC.

The BTH-820/BTA-830 can be charged either from the included AC/DC adapter or from a USB port. To fully charge them, you need over 2 hours. Both devices indicator LEDs turn off when they are fully charged. The built-in Li-Ion battery lasts (according to the specs) around 7-8 hours. From our tests, we didn't notice times higher than 5 hours which most users should find acceptable.

We didn't have any major installation problems, except for the case of the PDA. Even if its not Globalsat's fault, a web page with instructions and workarounds would be highly appreciated.

The sound quality was acceptable in most cases. The device's built-in power is not that high, resulting in a weak bass and an almost flat sound. The effective range of the receiver is around 7-8 meters, depending on walls and other obstacles. Beyond that, the sound was distorted and at times stopped.

Connecting the BTH-820 with a PDA caused skipping. The problem is mostly related to the PDA device and not the BTH-820 itself. There is a related topic over at the Aximsite, that might help you overcome such problems.

Using the BTH-820 with a mobile phone and a PDA will allow you to take your incoming calls while listening to music. The procedure is easy, just press the ">" button and speak. The music of course will stop playing and after you finish the call, pressing the ">" button returns to the music. You can also perform a redial function by pressing and holding >> or << for 2 seconds. You can initiate voice dialing by pressing and holding the play key for 2 seconds. The included microphone is not the best we have used, since our caller on the other line, reported noise and static.

The BTH-820 can be also used to remote control Windows Media player, either under WinXP or Windows 2003 SE (PDA).

The BTA-830 worked very well with the BTH-820. However, we witnessed skipping, not constant but random, up to 1-2 seconds. The BTA-830 can be used with any brand of BT Headset. We tried a BT Headset from Sony Ericsson (HBH-660) and after the pairing procedure, it worked without any problems.

7. Conclusion

Globlsat's Entertainment pack comprises a Bluetooth Dongle, a Bluetooth Headset and a Bluetooth Audio Gateway. All three devices performed very well and we were generally satisfied with them. The included documentation is not what we would expect from Globalsat, so inexperienced users may have difficulties (connection problems with PDAs). After searching around the net, we found work arounds for most of our issues, but we feel Globalsat should have addressed this beforehand.

The BTA-806 (BT Dongle) is small, has a very good connection manager and worked without problems with all tested BT enabled devices. The BTH-820 is a BT Headset that works with all BT enabled devices (PDAs, Mobile phones, BT Gateways). Its installation with PDAs require some additional steps, since Win2003SE doesn't fully support it. Lastly, the BTA-830 is a BT gateway that will unleash the power of portable music devices like iPods, providing wireless audio transmission.

While we haven't tested similar devices from other manufacturers, we were more than satisfied from the overall performance. The retail price won't trouble you either, since the BTH-820/BTA-830 package costs around US$88.
