Bluetooth Discovery app allows you to scan and find the device you want to connect to. This is a useful tool for finding any Bluetooth device, whether it is a smartphone, a tablet, a laptop, or even a desktop. The app will search for a device with the same UUID as the one you want to connect to. Once it is found, it will be paired with your device. You can then view its information, such as its Bluetooth signal strength, its Bluetooth profile, and its MAC address.

You can also use the app to pair with a device. If it is a smartphone, for example, you can pair with it by tapping on the "Pair with smartphone" button. If it is a tablet, you can do the same by tapping on the "Pair with tablet" button. The device you want to pair with must be close to you. The closer it is, the stronger the signal will be.

The Bluetooth Discovery app is a free app. You do not need to pay to use it.
