Standard Serial over Bluetooth link (COM13) Driver

The Standard Serial over Bluetooth link (COM13) driver allows Windows applications to communicate with a paired Bluetooth device through a virtual serial port. Provided by Microsoft, this Windows component is useful for compatible equipment that uses Bluetooth serial communication, such as scanners, diagnostic tools, and GPS receivers. COM13 identifies the assigned port on your computer rather than a specific hardware model.

Key Features

• Virtual serial communication: Enables applications that use COM ports to exchange data with compatible Bluetooth devices.
• Windows integration: Works with the Microsoft Bluetooth stack when the Bluetooth adapter and connected device support the required serial profile.
• Application connectivity: Lets you select COM13 in supported software to connect to paired equipment without a physical serial cable.
• Device management: Appears in Device Manager, where you can check device status, review driver details, and troubleshoot connection problems.

How to Install Standard Serial over Bluetooth link (COM13) Driver

1. Check your Windows version. This device entry is associated with Windows 10, 8.1, 7, Vista, and XP. Before choosing a Standard Serial over Bluetooth link (COM13) driver download for Windows, confirm compatibility with your operating system and Bluetooth adapter. Do not assume an older package supports Windows 10/11.
2. Verify the Bluetooth adapter. Open Device Manager and check that your Bluetooth adapter is enabled and working. If it has a warning icon, install the appropriate adapter driver from its manufacturer or through Windows Update first.
3. Pair your serial-capable device. Turn on the device and pair it through Windows Bluetooth settings. Depending on the Windows version and device, you may need to enable its serial service or add a Bluetooth COM port.
4. Install or update the Windows component. Windows normally installs the Microsoft serial-over-Bluetooth driver automatically. If the COM13 entry shows an error, open its properties in Device Manager and use the driver update option. Prefer Windows Update or an official manufacturer source if a separate package is required; a free download should not require third-party driver utilities.
5. Test the connection. Select COM13 in your application and use the communication settings recommended by the connected device’s manufacturer. If Windows assigns a different port number, select that port instead.

Keep your Bluetooth adapter software and Windows components updated to maintain reliable connections. The latest version available for your specific operating system is the appropriate choice—not necessarily the newest package overall. Older Windows releases may have limited driver availability, so check compatibility before making changes.

Common Issues and Fixes

• Install fails or COM13 does not appear: Pair the Bluetooth device again, then open Bluetooth settings > More Bluetooth options > COM Ports and add an Outgoing port. Restart the Bluetooth Support Service and reboot before reinstalling.
• Device not detected: Confirm the serial device is paired and powered on, enable “Show hidden devices” in Device Manager, and remove stale COM port entries. Check that the app is set to COM13 and not an older port.
• Version conflicts: If a vendor Bluetooth stack or third-party serial driver is installed, update or roll back the Bluetooth adapter driver in Device Manager. Prefer the Microsoft “Standard Serial over Bluetooth link” driver and avoid forcing generic USB-to-serial drivers.
