Standard Serial over Bluetooth link (COM17) Driver

The Standard Serial over Bluetooth link (COM17) driver lets Windows applications communicate with a paired Bluetooth device through a virtual serial port. This Microsoft component is useful for equipment that uses the Bluetooth Serial Port Profile (SPP), such as compatible scanners, GPS receivers, and serial adapters. COM17 is the port number assigned by Windows, not a separate hardware model.

Key Features

• Virtual serial communication: Allows software that expects a COM port to exchange data with compatible Bluetooth equipment without a physical serial cable.
• Windows integration: Works with the Windows Bluetooth stack to provide a serial connection after the remote device is paired and its serial service is available.
• Application compatibility: Lets you select COM17 in supported applications, provided that this is the port assigned to your device.
• Microsoft driver support: This component is generally supplied through Windows rather than as a standalone installer; the Bluetooth adapter may require its own manufacturer-provided driver.

How to Install Standard Serial over Bluetooth link (COM17) Driver

1. Check your Windows version and Bluetooth adapter. The listed supported systems are Windows 10, 8.1, 7, Vista, and XP. For Windows 10/11 searches, note that Windows 11 compatibility is not confirmed by this listing.
2. Use a trusted driver source. Before choosing a Standard Serial over Bluetooth link (COM17) driver download for Windows, check Windows Update and your computer or Bluetooth adapter manufacturer’s support resources. A free download should not require an unrelated driver-updater subscription.
3. Pair your Bluetooth device. Turn on Bluetooth, make the peripheral discoverable, and pair it using Windows settings. Confirm that the peripheral supports a Bluetooth serial service.
4. Check Device Manager. Look under “Ports (COM & LPT)” for the serial link. If it shows a warning, open its properties to review the error, then use the driver update option. You may also need to install the correct Bluetooth adapter driver.
5. Configure and test your application. Select COM17 if that is the assigned port, apply any communication settings required by the equipment, and test the connection. Windows may assign a different COM number after re-pairing.

Keep the driver and Bluetooth adapter software updated through trusted sources. The latest version suitable for your system depends on your Windows release and adapter, so avoid assuming one package fits every PC. If communication stops after an update, check pairing status and the assigned COM port before reinstalling drivers.

Common Issues and Fixes

• Install fails or COM port not created: Confirm the Bluetooth device is paired and its serial service is enabled. In Device Manager, uninstall any yellow-marked “Standard Serial over Bluetooth link,” then scan for hardware changes. If COM17 is reserved, change it under Ports > Properties > Port Settings > Advanced.
• Device not detected: Turn Bluetooth on, remove and re-pair the device, and check Bluetooth settings for an incoming/outgoing COM port. Disable airplane mode and restart the Bluetooth Support Service.
• Version conflicts or duplicate ports: Use the Microsoft in-box driver; do not force a third-party serial driver. Roll back or uninstall duplicate Bluetooth serial entries, assign a free COM number, and reboot.
