4.1.1 Central

BLE Central devices discover and listen to BLE devices that are advertising. These devices are capable of establishing connection to Peripherals. Central devices are also capable of establishing multiple connections (multilink) at the same time. There are certain use cases where a connection between the devices (Peripheral and Central) is not essential and scanning (Receive only, no transmit) feature alone is sufficient. These type of devices are called observers.
