Standard Serial over Bluetooth link (COM14) Driver

The Standard Serial over Bluetooth link (COM14) driver allows Windows applications to communicate with compatible Bluetooth devices through a virtual serial port. This Microsoft-associated component is useful when a Bluetooth accessory, such as a scanner, GPS receiver, or serial adapter, needs a COM-port connection rather than a USB cable. COM14 is the port number assigned on your computer, not a separate hardware model.

Key Features

• Virtual serial communication: Provides a COM-port interface for Bluetooth accessories that support the Serial Port Profile (SPP).
• Application compatibility: Lets software that uses serial connections access a paired Bluetooth device through its assigned port.
• Windows integration: Works with the Bluetooth stack and adapter driver to support serial communication without a physical serial connector.
• Configurable port settings: Allows supported communication settings to be reviewed in Device Manager and matched to your accessory or application.

How to Install Standard Serial over Bluetooth link (COM14) Driver

1. Check your Windows version and Bluetooth adapter. The listed operating systems are Windows 10, 8.1, 7, Vista, and XP. For Windows 10/11 systems, check compatibility separately; Windows 11 is not included in this page’s supported OS list.
2. Choose a trusted source. Before starting a Standard Serial over Bluetooth link (COM14) driver download for Windows, check Windows Update and your computer or Bluetooth adapter manufacturer’s support resources. This virtual-port component is often supplied through Windows rather than a standalone installer. Prefer an official free download over third-party driver utilities.
3. Install or update the Bluetooth adapter driver if needed. Use a package matching your hardware and Windows version, then restart if prompted. Do not force an incompatible driver onto the virtual serial port.
4. Pair your Bluetooth accessory. Open Windows Bluetooth settings, pair the device, and enable its serial service if required. Windows should create the appropriate virtual COM port when supported by the accessory and Bluetooth stack.
5. Confirm the connection. In Device Manager, check “Ports (COM & LPT)” for the Bluetooth serial entry and any warning icons. Select COM14 in your application only if that is the port Windows assigned; otherwise, use the displayed port number.

Keep your Bluetooth adapter software and Windows components updated to help resolve connection problems. The latest version should be the newest compatible release for your system—not simply the newest package available. If communication still fails after an update, check pairing, the accessory’s serial-service support, and the application’s selected COM port.

Common Issues and Fixes

• COM14 not detected or “device not found”: Confirm the Bluetooth device is paired and powered on, then in Device Manager enable View > Show hidden devices and check Ports (COM & LPT). Remove any stale “Standard Serial over Bluetooth link” entries, reboot, and re-pair.
• Driver install fails or rolls back: Install the Microsoft Bluetooth stack/driver through Windows Update rather than forcing an INF. Disable third-party Bluetooth software temporarily, uninstall the affected device in Device Manager, then scan for hardware changes.
• COM14 conflicts or version mismatch: If another device uses COM14, open the Bluetooth link’s Properties > Port Settings > Advanced and assign a free COM port. Remove old serial-over-Bluetooth entries and update the Bluetooth adapter driver to avoid stack conflicts.
