4] Update the Bluetooth drivers

The presence of an outdated Bluetooth driver may also initiate similar bugs on the computer. So, it’s better to check if there lies any pending update to this or not. And in case there exists any update, download and install the same. The best way to perform this task is via the Device Manager. Here’s how to update the Bluetooth drivers in Windows 10 –

• Right-click on the Windows icon and select Device Manager.
• Click “>” left of the Bluetooth to expand this section.

• On the succeeding screen, hit “Search automatically for drivers”.
• The system will then immediately start searching for any pending updates. If there indeed lies any pending update, the system will automatically download and install the same. 
• After completing the above steps, reboot your device.

When Windows 10 reloads, check if the error gets resolved or is still hanging on your computer. 

5] Manually install the Bluetooth driver

With Windows 10 20H1 onward, Microsoft regularly provides an optional update that contains bug fixes for drivers, Windows components, and others. If you haven’t checked this already, give this a shot by visiting Settings > Update & Security > Windows Update > Optional update.

If you didn’t find any optional update there, you must manually check if there lies any latest version of the Bluetooth driver that you are currently using on your computer. Intel, Broadcom, and other big companies often bring an update to their software at their official sites. Visit your manufacturer’s site, and look for the section – Available downloads.

In case you find any recent version of the Bluetooth driver, download the same to your device. Just make sure to download the device driver matching your system architecture i.e. ARM64, x64, or x86. 

• When the download completes, double-click over the setup file to begin its installation. 
• If the UAC window prompts, hit Yes.
• Now, follow the onscreen instructions to complete the remaining steps. 
• In the end, hit the Finish button.

Close all running programs and restart Windows. From the next logon, the driver error BCM20702A0 should not exist anymore. 

6] Uninstall Bluetooth and Universal Serial Bus Controllers

• Press Win + X to launch the Power Menu.
• Select Device Manager.
• Expand the Bluetooth section, right-click over the available driver, and hit uninstall device.
• Similarly, uninstall all the drivers that lie under the Universal Serial bus controllers.

• The system will automatically install all the drivers that were uninstalled previously.
