Mini USB Bluetooth 4.0 Adapter - 50m (165ft) Class 1 EDR Wireless Dongle

Bluetooth Class

Bluetooth classes define a Bluetooth device’s maximum power output; the higher a device’s output power, the longer the maximum range. The below table outlines the average power output and range of the four Bluetooth classes:

A device's maximum range can also depend on environmental factors, such as physical obstructions between the two Bluetooth devices.

In order to achieve the maximum range defined by a Bluetooth class, both devices must support the same class. For example, if you wish to communicate at a 100m range, both Bluetooth devices will need to be class 1 devices. If one of the devices is class 2, both devices will operate at the range of class 2.

Bluetooth Profile

Bluetooth profiles are additional protocols that that more clearly define the Bluetooth standard for very specific uses. Profiles define exactly how Bluetooth technology is used in specific situations.

Some examples of Bluetooth profiles are Serial Port Profile (SPP), Human Interface Device (HID), Hands-Free Profile (HFP), and Headset Profile (HSP).

When you troubleshoot issues with a Bluetooth adapter, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following are not the source of the issue:

• Operating system
• Up to date drivers
• Range

It’s important to make sure that the operating system that is being used with the Bluetooth adapter is supported by the device. You can be check which operating systems a device supports on the StarTech.com product page, under the Technical Specifications tab for the device.

The most up-to-date drivers and software should be used with the Bluetooth adapter. These are found on the StarTech.com website on the product page, under the Support tab.

It is important to be aware of the range of the Bluetooth adapter, and the distance to the Bluetooth device that pairing is being attempted with. The range of the adapter can also be viewed under the Technical Specifications tab for the device.

If the source of the issue has still not been found, these can be investigated:

• Detection on system
• Bluetooth device
• USB port
• Computer system
• Bluetooth adapter

If the Bluetooth adapter is not being detected by the computer while connected to your computer, refer to the following FAQs, based on your operating system:

• For Windows: www.startech.com/faq/usb-cannot-detect-windows.
• For Mac OS: www.startech.com/faq/usb-cannot-detect-mac-os.

If you encounter issues pairing with a Bluetooth device, another device should be tested (if possible).

If the adapter is not functional in the first USB port on the first computer system that is used, additional ports and an additional computer system should be tried.

If you have a second Bluetooth adapter, you should test with it as well.
