Bluetooth Virtual COM4 Driver

The Bluetooth Virtual COM4 driver helps Windows use a virtual serial port associated with a Bluetooth connection, allowing compatible software to communicate through COM4. Listed under Ugt in the Other device category, this driver is intended for users setting up Bluetooth serial communication or troubleshooting an unrecognized Bluetooth Virtual COM4 entry in Device Manager.

Key Features

• Virtual serial-port support: Helps applications that use COM ports communicate with a compatible Bluetooth-connected device.
• Device recognition: Provides the driver support Windows needs to identify and configure the Bluetooth Virtual COM4 interface.
• Legacy Windows coverage: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP; check the individual package for your specific Windows edition and architecture.
• Troubleshooting support: Installing a matching driver may resolve missing-driver warnings or communication problems caused by an incorrect installation.

How to Install Bluetooth Virtual COM4 Driver

1. Check your device and Windows version. Open Device Manager and locate Bluetooth Virtual COM4, which may appear under Ports (COM & LPT) or Other devices. Review its properties and hardware IDs to help confirm the correct package.
2. Choose a compatible package. Before starting your Bluetooth Virtual COM4 driver download for Windows, check the supported operating systems and whether the package matches your 32-bit or 64-bit system. For Windows 10/11 searches, note that Windows 11 is not included in the supplied compatibility list.
3. Download and extract the files. Use a trusted source and scan the package before opening it. If a free download is offered, verify that it contains the intended driver rather than an unrelated installer.
4. Install the driver. Run the included setup program, if provided. Otherwise, right-click the device in Device Manager, select Update driver, and browse to the extracted driver folder. Older Windows versions may use slightly different menu labels.
5. Verify the connection. Restart if prompted, then check that Device Manager shows no driver warning. Confirm that your Bluetooth device is paired and that your application uses the assigned COM port; the port number may differ after reinstallation.

Keep a copy of your working driver before you update. Choose the latest version that explicitly supports your device and operating system, rather than assuming a newer package will work better. If an update causes connection problems, use Device Manager’s rollback option when available.
