Standard Serial over Bluetooth link (COM23) Driver

The Standard Serial over Bluetooth link (COM23) driver lets Windows applications communicate with a compatible Bluetooth device through a virtual serial port. This Microsoft Windows component is useful if your Bluetooth GPS receiver, scanner, diagnostic adapter, or other serial accessory requires a COM-port connection rather than a cable. COM23 identifies the port assigned on your computer, not a separate hardware model.

Key Features

• Virtual serial communication: Provides a COM-port interface for applications that exchange serial data with compatible Bluetooth accessories.
• Windows integration: Works with the Windows Bluetooth stack to support serial connections when the paired device offers the required Bluetooth service.
• Application compatibility: Allows software with serial-port support to select COM23 and communicate with the connected accessory.
• Connection troubleshooting: Restoring the appropriate driver can help resolve missing-port or driver-related errors, although pairing and Bluetooth adapter issues may need separate attention.

How to Install Standard Serial over Bluetooth link (COM23) Driver

1. Check your Windows version. This listing covers Windows 10, 8.1, 7, Vista, and XP. Confirm your operating system and whether it is 32-bit or 64-bit before choosing any package. For Windows 10/11 systems, start with Windows Update; this listing does not establish Windows 11 compatibility.

1. Choose a trusted source. Before starting a Standard Serial over Bluetooth link (COM23) driver download for Windows, check whether Windows can supply the component automatically. A free download should come from an official source, such as Microsoft or your computer manufacturer, with compatibility verified.

1. Pair the Bluetooth accessory. Turn on Bluetooth, make the accessory discoverable, and pair it through Windows Bluetooth settings. Ensure it supports serial communication; not every Bluetooth device creates a COM port.

1. Install or update the driver. Open Device Manager, locate the entry under Ports (COM & LPT), and select the option to update its driver. Let Windows search automatically, or browse to a verified, compatible driver package if you have one.

1. Test the connection. Restart if prompted, then select COM23 in your application. Confirm any required serial settings using the accessory’s documentation. If Windows assigns a different port number, use that number instead.

Keep the driver and your Bluetooth adapter software updated through trusted channels. The latest version available for your particular Windows release is generally the appropriate choice—not necessarily the newest package overall. If communication already works reliably, avoid installing unrelated drivers simply because they mention COM23.

Common Issues and Fixes

• Install fails or rolls back: Confirm the Bluetooth radio is on and the device is paired before installing. Remove “Standard Serial over Bluetooth link (COM23)” in Device Manager (enable Show hidden devices), restart, re-pair, then let Windows install the Microsoft inbox driver via Windows Update.
• Device not detected / COM23 missing: Verify the paired device exposes a serial (SPP) service and that COM23 appears under Ports. Delete the pairing, re-pair, and restart the Bluetooth Support Service. Close apps that may be holding the port.
• Version or COM-port conflicts: If COM23 is in use or duplicate ports appear, assign a free COM number in the port properties and remove stale hidden COM entries. Prefer the Microsoft inbox driver; avoid forcing older OEM Bluetooth serial drivers.
