Bluetooth device shows "Code 39" error in Device Manager on Windows 10 laptop

[yogesh1]

I'm encountering an issue with my Bluetooth device on my Windows 10 laptop. In Device Manager, the Bluetooth device is displaying an error message: "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)".

Here are some additional details about the problem:

• My laptop model is HP R007tx, and it is Bluetooth-capable.

• Despite the Bluetooth hardware being present, the device manager shows this error, indicating a problem with the device driver.

• When attempting to troubleshoot, I found that the Bluetooth driver's digital signature cannot be verified, suggesting a revoked signing certificate.

I've already tried the following troubleshooting steps without success:

• Reinstalling Bluetooth drivers obtained from the HP support website.
• Updating Windows and checking for driver updates.
• Restarting the laptop multiple times.
• Checking for dependencies and performing a System File Checker scan.

Despite these efforts, the error persists, and I'm unable to use Bluetooth functionality on my laptop.

Can anyone provide guidance on how to resolve the "Code 39" error with the Bluetooth device driver? Is there a way to address the issue with the driver's digital signature or any other troubleshooting steps I can try?

Your assistance would be greatly appreciated. Thank you!

Laptop details:

• Make and model: HP R007tx
• Operating system: Windows 10
• Bluetooth device error: "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)"

The parts list for your notebook indicates that it comes with a Ralink RT3290LE 802.11bgn 1x1 Wi-Fi and Bluetooth 4.0 combination WLAN adapter.

FWIW, this is the correct W10 Bluetooth driver for your notebook:

MediaTek (Ralink) Bluetooth Software Driver

That model Bluetooth adapter does not work on the newer builds of W10 and there is no fix other than to:

Buy a USB Bluetooth adapter.

Replace the internal Ralink card with this model:

Realtek RTL8723BE 802.11bgn 1×1 + BT 4 LE Combo Adapter    HP part # 753077-001
