The BCM920702 Bluetooth 4.0 driver enables Windows to recognize the Bluetooth adapter and communicate with compatible wireless devices. Installing the appropriate package from the manufacturer can help resolve missing Bluetooth controls, adapter detection issues, and connection problems with peripherals such as mice, keyboards, and headsets.

Key Features

• Bluetooth adapter recognition: Provides the software interface Windows needs to detect and use the BCM920702 Bluetooth 4.0 hardware.
• Wireless peripheral connectivity: Supports pairing with compatible Bluetooth accessories, with available functions depending on the device and supported Bluetooth profiles.
• Connection management: Works with Windows Bluetooth settings to discover nearby devices, manage paired accessories, and reconnect when supported.
• Windows driver options: When selecting a download for Windows 11, 10, 8, or 7, match the package to your exact operating system and system architecture. Compatibility can vary between driver releases.

How to Install

1. Check your adapter and Windows version. Open Device Manager and look under Bluetooth or Other devices for the adapter. If its name is unclear, check Properties > Details > Hardware Ids to confirm that the download matches your hardware. Also verify whether Windows is 32-bit or 64-bit.

1. Download the matching driver. Choose a manufacturer-provided package intended for the BCM920702 Bluetooth 4.0 and your Windows version. For a built-in adapter, check whether the computer manufacturer supplies a model-specific package. Do not assume an older release is compatible with Windows 11.

1. Prepare the installation files. Save any open work, then extract the download if it comes in a compressed folder. If you use a Bluetooth keyboard or mouse, keep a wired alternative available in case the connection is temporarily interrupted.

1. Install the driver. Run the included setup program and follow its prompts. If no installer is provided, open Device Manager, right-click the adapter, select Update driver, and choose Browse my computer for drivers to point Windows to the extracted folder.

1. Restart and test Bluetooth. Restart the computer if prompted, enable Bluetooth in Windows settings, and pair a compatible accessory. If pairing fails, remove the existing pairing and try again. Check Device Manager for warning icons before troubleshooting individual peripherals.

Common Issues and Fixes

• Installer fails or exits early: Run the BCM920702 Bluetooth 4.0 package as administrator and use Windows compatibility mode for the Windows version it supports. Reboot before retrying.
• Device not detected: Check that Bluetooth is enabled in BIOS/UEFI and not disabled by airplane mode. In Device Manager, uninstall any unknown/disabled Bluetooth entries, then scan for hardware changes.
• Version conflicts: Remove existing Broadcom/WIDCOMM or generic Bluetooth drivers, reboot, and install the BCM920702 package matching your Windows build. Avoid mixing old vendor stacks with Windows’ built-in Bluetooth driver.
