Realtek Bluetooth UART Bus Driver for Windows 10 (Windows) Driver

The Realtek Bluetooth UART Bus Driver for Windows 10 (Windows) driver helps Windows communicate with compatible Realtek Bluetooth hardware connected through a UART interface. It is intended for users restoring Bluetooth functionality after a Windows installation, troubleshooting a missing adapter, or replacing an incompatible driver on a supported computer.

Key Features

• Enables communication between Windows and supported Realtek UART-connected Bluetooth hardware.
• Provides the bus-level support needed for Bluetooth operation alongside the appropriate Bluetooth adapter drivers and Windows services.
• Can help resolve driver-related detection problems, such as an unrecognized Bluetooth component in Device Manager, when the correct package is installed.
• Supports driver maintenance on compatible systems, with suitability determined by the computer model, hardware ID, and Windows version.

How to Install Realtek Bluetooth UART Bus Driver for Windows 10 (Windows) Driver

1. Identify your hardware and operating system. Open Device Manager and check the affected device’s Properties. Under Details, select Hardware Ids to help confirm compatibility. Also check your Windows edition and system architecture.
2. Choose a compatible package. Before starting the Realtek Bluetooth UART Bus Driver for Windows 10 (Windows) driver download for Windows, verify that the package matches your hardware and OS. For Windows 10/11 systems, check support explicitly; a Windows 10 package is not automatically suitable for Windows 11.
3. Download and prepare the files. Prefer a free download from your computer manufacturer or another verified official support source. Extract the archive if necessary, and read any included installation instructions. Save your work before proceeding.
4. Install the driver. Run the supplied installer and follow its prompts. If the package provides manual-installation files instead, open Device Manager, right-click the relevant device, select Update driver, and choose Browse my computer for drivers to locate the extracted folder.
5. Restart and test Bluetooth. Restart if prompted, then check Device Manager for warning icons. Enable Bluetooth in Windows Settings and try pairing a compatible accessory. If Bluetooth remains unavailable, your system may also require a separate Bluetooth adapter driver.

Keep the driver updated through Windows Update or your computer manufacturer’s support resources. The latest version should still match your specific hardware and operating system; a newer package is not necessarily the right update. If installation introduces problems, use Roll Back Driver in Device Manager when available.

Common Issues and Fixes

• Install fails (Code 10/28/52): Confirm the package matches Windows 10 and your CPU architecture (x64/ARM64). Extract the Realtek INF, then update the “Realtek Bluetooth UART Bus” device manually via Device Manager → Update driver → Browse. Run setup as administrator and reboot before retrying.
• Bluetooth device not detected: Check BIOS/UEFI for an enabled Bluetooth or UART/ACPI device, turn off Airplane mode, and look under System devices/Ports for an unknown UART device. If absent, rescan hardware; if present with a warning, install the Realtek UART driver against that device.
• Version conflicts with OEM/Windows Update drivers: Uninstall the existing Bluetooth and UART entries with “Delete driver software,” reboot, then install the Realtek package. Avoid mixing OEM and generic drivers; if Windows Update replaces it, roll back to the Realtek version.
