An Android device acting as both a peripheral and central device can communicate with other BLE peripheral devices while sending advertisements in peripheral mode. GATT server vs. GATT client. In this example, app provides an activity BluetoothDetectorActivity to connect and display data and display GATT services and characteristics supported by the device. To scan BLE devices, you use the startScan() method.Scanning is battery-intensive, you should observe the following guidelines: startScan() method takes a ScanCallback as a parameter. Starting with Android 10, apps that do BLE scanning need to request fine location permission, otherwise no results will be returned. Each service (which can be thought of a behavior) can contain one or multiple characteristics that encapsulate data. BLE is wireless technology.It gives context to the environment around you.It perfect for devices that run for long periods on power sources, such as coin cell batteries. The method is available in the BluetoothLeScanner class of the android.bluetooth.le for BLE scanning operations.
