Some Windows users suddenly encounter driver error BCM20702A0, which seems to indicate that the drivers for this device are not installed because there are no supported drivers. However, the vast majority of affected users report that the same device used to function normally with the exact same settings.
If you see this error in Windows 10, start by running the Windows Bluetooth troubleshooter and see if it solves the problem. In case the utility finds no problem with your current Bluetooth settings and you are using an HP laptop, install the Broadcom Bluetooth driver package.
However, you should also test whether corruption is responsible for this behavior. Try reinstalling the entire Bluetooth package along with each USB driver. But if the problem is caused by an operating system file, this issue will not be resolved unless a clean install is performed or the install procedure is repaired.

Broadcom Bluetooth Driver Installation (Windows only 10)
If you encounter the BCM20702A0 driver error on an HP controller or ultrabook, it is likely due to the lack of an updated version of the Bluetooth driver. HP notebook models are notorious for compatibility issues with various Bluetooth drivers.
This is quite common among machines that do not support Bluetooth natively., but they use a Bluetooth adapter like the Insignia 4.0 the equivalent.
In case this scenario is applicable, you should be able to fix the problem by installing Broadcom's full Bluetooth driver package. To do this, follow the instructions below:
-
Click on this link (here) from your default browser and wait for the download to complete.
-
Next, right-click on the driver installer executable and choose Run as administrator from the context menu that just appeared. In User Account Control (UAC), click Yes to grant administrative privileges.
-
Once you are inside the Broadcom Bluetooth Driver for Windows screen 10, follow the on-screen instructions to start and complete the Bluetooth driver installation.
Installing the Broadcom Bluetooth Driver Pack -
After the installation is complete, reboot and see if the problem is fixed once the next computer startup completes.
In case you keep seeing the same error message, go to next possible solution.
Uninstalling each USB and Bluetooth driver
In case the troubleshooter was unable to resolve the issue and you have ensured that it is not a permissions issue, it's probably a corrupted Bluetooth driver or a faulty USB driver (in case you are using a dongle for Bluetooth).
In this case, the best scenario that will ensure you delete the corrupted instance is to uninstall all Bluetooth drivers (and the USB driver if you are using a dongle) to force install Windows to find and install the new equivalent drivers.
In case you don't know how to do this, follow the instructions below:
-
Press the Windows key + R to open the Run dialog. Then write $ 0027 devmgmt.msc $ 0027 and hit Enter to open a Run dialog.
Run devmgmt.mscNote: Si UAC (User account control) prompts you to click Yes to grant it administrative privileges.
-
Once you are inside the Device Manager, expand the drop-down menu associated with Bluetooth and then, right click> Uninstall all the drivers that are inside.
Uninstall all Bluetooth drivers -
In case you are using a dongle to equip your system with Bluetooth, you will also need to uninstall each USB driver under Universal Serial Bus Controllers.
Uninstalling drivers for USB controllersNote: if your computer supports Bluetooth natively, skip this step.
-
Restart the computer to force the operating system to install the missing drivers.
-
Repeat the action that caused the error above and see if the problem is already fixed.
In case the same problem continues to occur, scroll down to the next potential solution below.
Perform a clean install / repair facility
If none of the possible solutions above have worked for you, it is very likely that you are dealing with some kind of underlying OS corruption issue that ends up affecting the Bluetooth component. If this scenario is applicable, you should be able to fix this by updating all Windows components.
You can do this by going to a repair facility (on-site repair) or a clean installation.
A repair installation is a bit more tedious and will require you to use a compatible installation media, but the main advantage of this procedure is that the update process will only touch the files of your operating system: your personal media, your applications, your games and even some user preferences will remain intact.
A clean installation can be done without an installation media, but be prepared for total data loss unless you backup your data in advance.
