The Bluetooth LE Generic Attribute Service driver helps Windows recognize and communicate with services exposed by Bluetooth Low Energy devices. It supports the exchange of small amounts of data, such as sensor readings or accessory status, through the Generic Attribute Profile (GATT) rather than providing a separate wireless network connection.

Key Features

• Bluetooth LE service recognition: Helps Windows identify a connected accessory’s GATT services so compatible software can access its supported functions.
• Low-energy data exchange: Works with the Bluetooth stack to support communication between compatible peripherals and applications.
• Device Manager integration: Allows Windows to associate the service with the appropriate driver components, helping resolve missing-driver entries when a compatible package is installed.
• System-specific support: Driver availability depends on your Bluetooth adapter, accessory, and Windows version. Windows 11, 10, and 8 include native Bluetooth LE support, while Windows 7 generally requires a compatible manufacturer-provided Bluetooth stack.

How to Install

1. Check the device and Windows version. Open Device Manager and locate Bluetooth LE Generic Attribute Service, which may appear under Bluetooth or Other devices. Review its properties and confirm whether your system runs Windows 11, 10, 8, or 7, including the system architecture.

1. Choose a compatible driver. Use a package from the manufacturer that explicitly supports your Bluetooth hardware and operating system. This service may use Windows-provided components rather than a standalone driver, so check Windows Update and optional driver updates where available.

1. Install the required components. If the download includes an installer, run it and follow the prompts. For an extracted driver package, right-click the affected entry in Device Manager, select Update driver, and choose Browse my computer for drivers to point Windows to the extracted folder.

1. Restart and reconnect. Restart your PC if prompted, then turn on the Bluetooth accessory and keep it nearby. If the service remains unavailable, remove the accessory from Bluetooth settings and pair it again.

1. Verify operation. Check Device Manager for warning icons and test the accessory with its intended application. If installation fails, confirm compatibility and update the Bluetooth adapter driver; a service driver alone cannot add Bluetooth LE support to unsupported hardware.

Common Issues and Fixes

• Install fails or shows Code 10/28: Update or reinstall the Bluetooth adapter driver first—not just the GATT service—then run the Bluetooth troubleshooter and scan for hardware changes in Device Manager. Remove stale BLE pairings if installation still blocks.
• Device not detected: Confirm the BLE peripheral is in pairing/advertising mode and Bluetooth LE is enabled. Remove the old pairing, restart the “Bluetooth Support Service,” re-pair, and check Device Manager under Bluetooth/Other devices.
• Version conflicts after Windows/OEM updates: Roll back or update the manufacturer’s Bluetooth driver, uninstall the GATT device with “Delete the driver software,” reboot, and re-pair. Avoid mixing vendor and Windows inbox Bluetooth stacks.
