I-Bluetooth Special Interest Group (SIG) ikhiphe isizukulwane esisha sobuchwepheshe obujwayelekile be-Bluetooth 5.2 LE Umsindo ku-CES2020 e-Las Vegas. Ilethe umoya omusha emhlabeni we-Bluetooth.
Uthini umgomo wokudlulisa lobu buchwepheshe obusha? Sithatha esinye sezici zayo eziyinhloko i-LE ISOCHRONOUS njengesibonelo, ngethemba ukuthi lokhu kungakusiza ufunde kabanzi mayelana nobuchwepheshe obusha.
Umsebenzi wesiteshi esivumelanayo se-Bluetooth LE kuyindlela entsha yokudlulisa idatha phakathi kwemishini esebenzisa i-Bluetooth LE, ebizwa ngokuthi i-LE Isochronous Channels. Inikeza indlela ye-algorithmic yokuqinisekisa ukuthi amadivaysi amaningi owamukelayo angathola ngesikhathi esisodwa idatha kusuka kudivayisi eyinhloko. Iphrothokholi yayo ibeka ukuthi ifreyimu ngayinye yedatha ethunyelwa umthumeli we-Bluetooth izoba nomkhawulo wesikhathi, futhi idatha etholwe idivayisi yesigqila ngemva komkhawulo wesikhathi izolahlwa. Lokhu kusho ukuthi idivayisi yomamukeli ithola kuphela idatha ngaphakathi kwewindi lesikhathi elivumelekile, ngaleyo ndlela iqinisekise ukuvumelanisa idatha etholwe amadivayisi amaningi ezinceku.
Ukuze kuqashelwe lo msebenzi omusha, i-Bluetooth 5.2 yengeza isendlalelo sokuvumelanisa sokuvumelanisa se-ISOAL (I-Isochronous Adaptation Layer) phakathi kwesilawuli sesitaki sephrothokholi kanye Nosingathi ukuze kuhlinzekwe ukuhlukaniswa kokugeleza kwedatha kanye nezinsizakalo zokuhlela kabusha.
Isendlalelo se-ISOAL siguqula isendlalelo esiphezulu se-LE yedatha yesevisi ye-SDU (iyunithi yedatha yesevisi) ibe idatha yephrothokholi ye-PDU (iyunithi yedatha yephrothokholi) edingekayo ekudlulisweni kwe-baseband futhi okuphambene nalokho. Isilawuli se-ISOAL samukela noma sikhiqiza ama-SDU ngama-PHY wombhalo wekhodi we-1M no-2M asekelwe. Ubude obukhulu be-SDU ngayinye yi-Max_SDU. Sebenzisa iphakethe ledatha ye-HCI ISO ukuze udlulisele i-SDU isendlalelo esingaphezulu noma ukusuka kwesendlalelo esingezansi uye emoyeni.
Ezimeni zohlelo lokusebenza lwemodi exhunyiwe ye-LE nemodi engaxhumekile, iphrothokholi ye-Bluetooth 5.2 LE AUDIO icacisa amasethi amabili amamodeli ohlaka lokusakaza kokusakaza kwedatha.
