Standard Serial over Bluetooth link (COM15) Driver

The Standard Serial over Bluetooth link (COM15) driver lets Windows expose a compatible Bluetooth serial connection as a virtual COM port, allowing software to communicate with a paired device. Provided through Microsoft’s Bluetooth support, it is useful for users connecting equipment such as serial adapters, GPS receivers, or diagnostic devices that support the Bluetooth Serial Port Profile.

Key Features

• Virtual serial communication: Enables compatible applications to exchange data over Bluetooth using a COM port instead of a physical serial cable.
• Windows integration: Works with Microsoft’s Bluetooth stack and Device Manager to manage the serial connection. Your Bluetooth adapter must also have a working driver.
• Application compatibility: Supports software that communicates through standard serial ports. Select COM15 in your application if that is the port Windows has assigned to the connection.
• System-specific support: Intended for compatible configurations running Windows 10, 8.1, 7, Vista, or XP. The appropriate driver depends on the Windows version, system architecture, and Bluetooth hardware.

How to Install Standard Serial over Bluetooth link (COM15) Driver

1. Check your system and device. Confirm your Windows edition and whether it is 32-bit or 64-bit. In Device Manager, look under “Ports (COM & LPT)” and “Bluetooth” for the device or any warning symbols.
2. Choose a trusted source. Before starting a Standard Serial over Bluetooth link (COM15) driver download for Windows, check Windows Update or your computer manufacturer’s support resources. Microsoft’s serial Bluetooth support is often included with Windows, so a separate installer may not be necessary. Use a trusted free download source if an additional package is required.
3. Install or update the driver. Install the verified package according to its instructions, or right-click the device in Device Manager, select “Update driver,” and let Windows search. For an extracted compatible package, choose the option to browse your computer.
4. Pair the Bluetooth equipment. Ensure the remote device supports serial communication, then pair it through Windows Bluetooth settings. Windows may assign a port other than COM15; the number identifies the connection, not a different driver model.
5. Test the connection. Select the assigned COM port in your application and use the communication settings recommended by the equipment manufacturer. Restart Windows if prompted.

Keep your Bluetooth adapter and serial connection drivers updated using trusted sources, choosing the latest version compatible with your system rather than simply the newest package available. For Windows 10/11 troubleshooting, confirm OS-specific compatibility first: Windows 11 is not included in this page’s listed supported systems. An update may address connection issues, but pairing and application settings also matter.

Common Issues and Fixes

• Install fails or driver won’t load: This device normally uses Microsoft’s in-box Bluetooth serial driver, so avoid third-party “COM15” drivers. Run Windows Update and the Bluetooth troubleshooter, then re-pair the device.
• Device not detected / COM15 missing: Confirm Bluetooth is on and the device is paired. In Device Manager, enable Show hidden devices, check Ports (COM & LPT), and re-pair if the Standard Serial over Bluetooth link entry is absent.
• Version or COM-port conflicts: Remove stale or duplicate Bluetooth COM ports in Device Manager, reboot, and let Windows reinstall the inbox driver. If another app holds COM15, close it or assign a different COM port in port properties.
