Standard Serial over Bluetooth link (COM24) Driver

The Standard Serial over Bluetooth link (COM24) driver lets Windows present a compatible Bluetooth connection as a virtual serial port, allowing software to communicate with paired devices through COM24. This Microsoft component is useful when connecting equipment that supports Bluetooth serial communication, such as certain scanners, GPS receivers, or measurement instruments.

Key Features

• Virtual serial communication: Provides a COM-port interface for applications that exchange data with compatible Bluetooth devices.
• Windows integration: Works with the Windows Bluetooth stack to support serial connections without a physical serial cable.
• Application compatibility: Allows software with serial-port settings to use COM24 when that port is assigned to the intended Bluetooth device.
• Connection management: Makes the virtual port available in Device Manager, where you can check its status and troubleshoot driver issues.

How to Install Standard Serial over Bluetooth link (COM24) Driver

1. Check your Windows version. This device listing covers Windows 10, 8.1, 7, Vista, and XP. Confirm your operating system and architecture before selecting any package. If you use Windows 10/11, start with Windows Update; this listing does not establish Windows 11 package compatibility.
2. Verify the Bluetooth adapter. Open Device Manager and confirm that your Bluetooth adapter is working. A missing or faulty adapter driver can prevent the serial port from appearing, even when the virtual-port component is available.
3. Choose a trusted source. Before starting a Standard Serial over Bluetooth link (COM24) driver download for Windows, check whether Windows can supply the component automatically. It is commonly included with Windows rather than offered as a separate installer. Treat any free download claiming universal compatibility with caution.
4. Install or update the driver. In Device Manager, find the entry under “Ports (COM & LPT),” right-click it, and select the driver-update option. Search automatically, or browse to a verified, compatible package if you have one.
5. Pair and test your device. Ensure the Bluetooth device supports serial communication, then check the assigned port and select it in your application. COM24 is a local port assignment, not a hardware model; Windows may assign a different number after pairing again.

Keep the driver updated through Windows Update and maintain the Bluetooth adapter’s driver using its manufacturer’s guidance. The latest version should match your Windows release and hardware—not simply have the highest version number. If communication fails after an update, check pairing, port selection, and application settings before reinstalling drivers.

Common Issues and Fixes

• Install fails or COM24 never appears: Remove the Bluetooth pairing and any hidden “Standard Serial over Bluetooth link” entries in Device Manager (View > Show hidden devices), reboot, then re-pair the device. Confirm an inbound COM port is enabled in Bluetooth settings.
• Device not detected: Put the Bluetooth device in discoverable/pairing mode, verify Bluetooth Support Service is running, and delete stale pairings. Check Device Manager > Ports for the actual assigned COM number; Windows may not keep COM24.
• Driver or COM-port conflicts: Use Microsoft’s built-in Bluetooth serial driver and uninstall third-party Bluetooth stacks or virtual COM tools that override it. Reinstall “Microsoft Bluetooth Enumerator,” then change COM24 to a free port under Ports > Properties > Advanced if it is in use.
