Bluetooth 5.4 adapter for Windows PCs

The AUTYUE Q2545_B adds Bluetooth 5.4 with EDR and BLE to desktop and laptop computers running Windows 11, 10, 8.1 or 7. It connects up to seven peripherals such as headsets, keyboards, mice, speakers and printers at the same time. The adapter is not compatible with macOS, Linux, game consoles, car audio systems or TVs. It also does not work with 2.4 GHz wireless keyboard and mouse dongles.

Low-energy wireless with external antenna

Bluetooth 5.4 Low Energy reduces power draw during idle and active transfers while the external antenna helps maintain a stable link up to 328 feet in open space. The adapter reaches a maximum transfer rate of 5 Mbps and uses the 2.4 GHz band with improved anti-interference performance. Backwards compatibility extends to Bluetooth 2.0, 2.1, 3.0, 4.0, 5.0, 5.1, 5.2 and 5.3 devices.

USB plug-and-play on supported Windows versions

Insert the dongle into any free USB port on Windows 11, 10 or 8.1 for driver-free operation; Windows 7 requires a manual driver install from the included CD. The stick supports profiles including A2DP, AVRCP, HID, PAN, HCRP, Serial Port, Object Push, File Transfer and PIM Sync. It frees up cabled connections for audio, input and printing peripherals.

Questions about this item

How do I install the AUTYUE Q2545_B adapter on Windows 11?

Insert the USB stick; Windows 11 recognises it automatically with no driver required. The step people miss is removing any older Bluetooth dongle first, otherwise the system keeps using the legacy radio.

Will the external antenna on the Q2545_B need replacement?

The antenna is fixed to the dongle and has no moving parts, so no periodic replacement is expected. Keep the USB port clean and avoid bending the antenna sideways to maintain the 328 ft range.

What limits the 5 Mbps transfer rate during long file transfers?

Sustained throughput is capped by the Bluetooth 5.4 EDR PHY at 5 Mbps and the single USB 2.0 endpoint, so large transfers will plateau at that ceiling rather than the advertised burst speed.
