After testing across 20+ laptops, these driver versions provide the most stable experience on Windows 11 22H2 and 23H2:
| Version | Date | Source | Stability | Notes | |---------|------|--------|-----------|-------| | 12.0.1.1010 | Nov 2019 | Dell/HP | Excellent | Best overall | | 12.0.1.940 | June 2018 | Lenovo | Good | No LE audio | | 14.0.0.3 (Modded) | 2021 | Community | Fair | Requires signature bypass | | Microsoft 10.0.22621.1 | Inbox | Microsoft | Poor | No advanced features |
💡 Pro tip: After installing version 12.0.1.1010, disable Bluetooth power saving: Go to Device Manager → Bluetooth adapter → Power Management → Uncheck "Allow the computer to turn off this device".
Windows 11 has stricter driver signing requirements and deprecates older Bluetooth stacks (e.g., Microsoft’s generic Bluetooth enumerator often fails with pre-2016 Broadcom chips). Many BCM2045A0-based modules rely on proprietary drivers that Microsoft does not distribute via Windows Update.
Try Windows Update first
Install Broadcom/Widcomm driver
Use generic Microsoft Bluetooth driver
Manual INF driver install (advanced)
Troubleshooting
The BCM2045A0 is a Bluetooth chipset manufactured by Broadcom. It is commonly found integrated into Wi-Fi/Bluetooth combo cards used in laptops from manufacturers like HP, Dell, Lenovo, and Acer. When Windows 11 cannot find a specific driver for this chipset during installation, it labels it by its Hardware ID (BCM2045A0) rather than a user-friendly name, leaving the Bluetooth functionality disabled.
