The Broadcom 43142 Bluetooth 4.0 Adapter driver allows Windows to recognize the adapter and communicate with compatible Bluetooth devices. Installing the correct Broadcom driver can help restore missing Bluetooth controls and resolve pairing or connection problems caused by an outdated or incompatible driver.

Key Features

• Bluetooth device connectivity: Supports connections to compatible accessories such as mice, keyboards, headsets, and speakers, depending on the accessory’s requirements and available Bluetooth profiles.
• Bluetooth 4.0 functionality: Enables the adapter’s supported Bluetooth capabilities, including low-energy communication where supported by the driver, operating system, and connected device.
• Windows integration: Lets Windows detect and manage the adapter through Device Manager and the operating system’s Bluetooth settings.
• Driver-related troubleshooting: Replacing a missing, damaged, or unsuitable driver may resolve adapter detection errors and unreliable connections. Wireless interference and accessory issues may require separate troubleshooting.

How to Install

1. Check your adapter and Windows version. Open Device Manager and look for the Broadcom 43142 Bluetooth 4.0 Adapter under Bluetooth. If it appears as an unknown device, check its hardware IDs in Properties. Confirm whether you use Windows 11, 10, 8, or 7 and whether your installation is 32-bit or 64-bit.

1. Choose a matching driver package. Verify that the download supports your hardware ID, Windows version, and system architecture. Prefer a package approved by your computer manufacturer when available. Compatibility can vary by laptop model, particularly on Windows 11; a driver intended for an older release is not automatically compatible.

1. Prepare and run the installer. Extract the downloaded archive if needed, then launch the setup application and approve the administrator prompt. Keep Bluetooth accessories nearby, but wait until installation finishes before pairing them.

1. Use Device Manager if no installer is included. Right-click the adapter or matching unknown device, select Update driver, and choose Browse my computer for drivers. Point Windows to the extracted folder and follow the prompts.

1. Restart and test Bluetooth. Reboot the computer, enable Bluetooth in Windows, and try pairing an accessory. If the adapter still shows a warning icon, review its Device Manager status and confirm that you selected the correct package before trying another driver.

Common Issues and Fixes

• Install fails or shows Code 10: The Broadcom 43142 package may reject newer Windows versions. Run the installer as administrator, try Windows 8 compatibility mode, then update manually in Device Manager by pointing to the extracted driver folder.
• Bluetooth adapter not detected: Confirm Bluetooth is enabled in BIOS and via the laptop’s Fn key or physical switch. In Device Manager, show hidden devices, uninstall any unknown/ghost Bluetooth entries, and rescan hardware.
• Driver version conflicts: Remove older Broadcom/WIDCOMM or generic Windows Bluetooth drivers first. Uninstall the device with “Delete the driver software,” reboot, install the Broadcom 43142 package, then roll back if Windows Update replaces it.
