In recent times, some Windows 10 users have seen an error code BCM20702A0, when using Bluetooth and they are concerned as to what it is all about. We can say for certain that it has something to do with your Bluetooth driver. The error message in question is:
The drivers for this device are not installed. There are no compatible drivers for this device.
The problem here tends to no longer allow specific Bluetooth components to properly communicate with your Windows 10 operating system. It also affects laptops that do not have native Bluetooth support; therefore, the manufacturer installed a dongle on the inside to deliver the service. This is not the best way to do things because native support is always better. On the other hand, maybe you’re using a Broadcom USB Bluetooth dongle that is acting up, and as such, the error is showing.
Below are solutions provided for this particular error and how to eliminate it.
Press ⊞ WINDOWS to open the menu and select settings
In settings choose Update & Security
Go to troubleshoot and on the right panel click on additional troubleshooters
Click on Bluetooth
Select Run the troubleshooter, then sit back and allow the tool to do its thing. Once you’ve completed the task, click on Apply this fix if any repairs are needed
Reboot your computer
Windows drivers for Broadcom Bluetooth devices are no longer posted on their website. They should be available through Microsoft’s Windows Update service. If drivers were not downloaded automatically by Windows Update, use Device Manager to refresh the driver from Windows Update.
However, the Broadcom Bluetooth drivers seem to be available here on the Lenovo website. To fix the BCM20702A0 driver error, you may download and install them.
After downloading it, right-click on the downloaded item, and select Run as administrator. After installation, restart your computer, then check again if it works.
If previous solutions did not work, go to device manager and remove all Bluetooth devices along with all USB controllers.
Reboot your computer and Windows will automatically reinstall and set all devices.
