Understanding BLE Technology in Modern Mobile Apps

Bluetooth Low Energy (BLE) is a wireless communication technology designed for low power consumption and efficient data transfer. BLE is widely used in healthcare devices, smart home systems, fitness trackers, and industrial IoT solutions. Mobile applications use BLE to communicate with nearby hardware devices in real time while maintaining battery efficiency. Android uses BluetoothGatt APIs while iOS uses CoreBluetooth for BLE communication. BLE enables apps to scan, connect, read characteristics, write data, and receive notifications from smart devices.
