Possible Causes of the "Can't Find Bluetooth Devices" Issue:
Driver Issues: The Bluetooth Drivers may be outdated, missing, or incompatible. Corrupted Drivers can prevent your system from properly detecting and communicating with Bluetooth devices. Bluetooth Disabled in BIOS: Sometimes, Bluetooth can be disabled in the BIOS settings of your computer, causing it not to function correctly. Interference from Other Devices: Other wireless devices (e.g., Wi-Fi routers, cordless phones, microwaves) may cause interference with Bluetooth signals. Bluetooth Radio Malfunction: The Bluetooth hardware itself (BCM43684B1KRFBG) might be experiencing issues, such as malfunction or a loose connection. Software Conflicts: Certain software, such as third-party antivirus programs or system utilities, can conflict with Bluetooth services and prevent devices from being detected. Windows Bluetooth Settings: Incorrect Bluetooth settings in Windows or issues with the Bluetooth service in the operating system can also result in this problem.Step-by-Step Solutions to Resolve the Issue:
1. Check and Update Bluetooth Drivers: Step 1: Press Windows + X and select Device Manager. Step 2: Expand the Bluetooth section and look for the BCM43684B1KRFBG device. Step 3: Right-click on it and select Update Driver. Step 4: Choose Search automatically for updated driver software. Step 5: If an update is found, allow it to install.

Resolve Interference Issues: Step 1: Make sure there are no other devices near your Bluetooth adapter that could interfere with its signal. Step 2: If using Wi-Fi, ensure the router is at least 3 feet away from the Bluetooth device, as the 2.4 GHz frequency can cause interference. Step 3: Try turning off or moving other wireless devices to minimize signal interference. 4. Check Bluetooth Service in Windows: Step 1: Press Windows + R, type services.msc, and press Enter. Step 2: In the Services window, locate Bluetooth Support Service. Step 3: Right-click on it and select Properties.
