How BLE Communication Works?
Bluetooth Low Energy (or Bluetooth LE, or Bluetooth Smart) is the power- and application-friendly version of Bluetooth that was built for the Internet of Things (IoT) devices. The main focus in BLE is low energy consumption which is achieved through Faster Connections and Lower Standby Time.
BLE communication consists of two main components: Advertising and Connecting. BLE Advertising is a one-way communication method. Devices that want to be discovered transmit packets of data in set intervals. On the other hand, there are listening devices (smart phones) scanning other devices; receiving and processing advertising packets and filtering them.
The device which advertises is called a Bluetooth Peripheral whereas the one doing the scanning is a Bluetooth Central device.
After a device is discovered, a connection is established. It is now possible to read the services that a Bluetooth Low Energy device offers, and for each service its characteristics (Implementation of a GATT profile). Each characteristic provides some value, which can be read, written, or both.
