Abstract
Bluetooth Low Energy (BLE) predstavljen je u inačici Bluetooth 4.0., sa svojstvom smanjene potrošnje energije uređaja koji međusobno komuniciraju. BLE radi u pojasu širine 2.4 GHz (ISM) koji je segmentiran u 40 radio frekvencijskih kanala, svaki širine po 2 MHz gdje se tri posljednja kanala koriste za oglašavanje a preostalih 37 za prijenos podataka. Arhitektura protokolnog stoga BLE-a čine slojevi kontroler, host i aplikacijski sloj sa pripadajućima slojevima. U komunikaciji mogu... More sudjelovati uređaji kao što su periferni uređaja, emiter, centralni uređaj i promatrač. Prije uspostave komunikacije uređaji se oglašavaju i skeniraju kako bi mogli prenositi međusobno podatke. U stanju oglašavanja, uređaj šalje pakete koji sadrže korisne podatke drugima koji ih primaju i obrađuju. Nakon uspostavljene veze definira se način na koji će jedan od uređaja, poslužitelj, predočiti svoje podatke klijentu što predstavlja ATT i format servisa i njihove karakteristike što predstavlja GATT. Sigurnost u BLE tehnologiji upravlja Security Manager (SM) koji definira protokole i algoritme za generiranje i razmjenu ključeva između dva uređaja. 2017. godine Bluetooth SIG predstavio je Bluetooth mrežni standard (eng. Bluetooth mesh) gdje više uređaja mogu međusobno slati poruke. Less
Abstract (english)
Bluetooth Low Energy (BLE) is introduced in Bluetooth version 4.0, with the property of reduced power consumption of devices that communicate with each other. The BLE operates in the 2.4 GHz band (ISM) which is segmented into 40 radio frequency channels, each 2 MHz wide where the last three channels are used for advertising and the remaining 37 for data transmission. The BLE protocol stack architecture consists of a controller, host, and an application layer with associated... More layers. Devices such as a peripheral device, emitter, central device, and an observer can participate in communication. Before establishing communication, the devices are advertised and scanned so that they can transmit data. In the advertising state, the device sends packets containing useful data to others who receive and process it. Once the connection is established, the way in which one of the devices, the server, presents its data to the client, which is ATT and the format of the service, and their characteristics, which is GATT, is defined. Security in BLE technology is managed by Security Manager (SM) which defines protocols and algorithms for generating and exchanging keys between two devices. In 2017, the Bluetooth SIG introduced the Bluetooth mesh standard, where multiple devices can send messages to each other. Less
