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.
