Sierra Wireless NMEA Port (COM22) Driver

The Sierra Wireless NMEA Port (COM22) driver lets Windows communicate with the NMEA serial interface exposed by a compatible Sierra Wireless modem or mobile broadband module. This interface can deliver GPS/GNSS positioning messages to navigation, mapping, and diagnostic software when the hardware supports location services. You may need this driver if the port appears as an unknown device, positioning software cannot access it, or you are reinstalling your modem’s drivers.

Key Features

• NMEA serial communication: Provides access to the module’s positioning-data interface so compatible applications can read available location messages.
• Device recognition: Helps Windows identify the Sierra Wireless NMEA port and expose it as a COM port in Device Manager.
• Application connectivity: Enables software that accepts NMEA data over a serial connection to use the port, provided location output is enabled on the module.
• Legacy Windows support: Driver packages may support Windows 10, 8.1, 7, Vista, and XP, depending on the modem model and package release. Choose the correct version for your hardware and operating system.

How to Install Sierra Wireless NMEA Port (COM22) Driver

1. Identify your hardware and Windows version. Open Device Manager and check the device’s hardware IDs under Properties > Details. Confirm whether your Windows installation is 32-bit or 64-bit.
2. Choose a compatible package. Before starting your Sierra Wireless NMEA Port (COM22) driver download for Windows, verify the supported modem models and operating systems. Select the latest version approved for your device, rather than assuming every Sierra Wireless package is interchangeable.
3. Download and extract the files. Use a trusted free download from the hardware manufacturer or computer maker where available. Extract a compressed package before installation.
4. Install the driver. Run the supplied installer, or right-click the device in Device Manager, select Update driver, and browse to the extracted driver folder. Restart if prompted.
5. Verify the connection. Check that the NMEA port appears without a warning icon, then select its assigned COM port in your positioning application. Windows may assign a number other than COM22; location output may also need enabling through the module’s supported software.

Keep the driver updated when a compatible release addresses connection problems or improves reliability. For Windows 10/11 systems, check support explicitly: Windows 10 compatibility does not automatically mean Windows 11 support. A driver update cannot add GPS/GNSS capability to hardware that lacks it.
