Iqela le-Bluetooth Special Interest Group (SIG) likhuphe isizukulwana esitsha somgangatho wobuchwephesha beBluetooth 5.2 LE Umsindo kwiCES2020 eLas Vegas. Izise impepho entsha kwihlabathi leBluetooth.
Uthini umgaqo wothumelo wobu buchwepheshe butsha? Ukuthatha enye yeempawu zayo eziphambili LE ISOCHRONOUS njengomzekelo, ngethemba lokuba oku kunokukunceda ufunde ngakumbi malunga netekhnoloji entsha.
Umsebenzi wesiteshi se-Bluetooth LE yindlela entsha yokudlulisa idatha phakathi kwezixhobo usebenzisa i-Bluetooth LE, ebizwa ngokuba yi-LE Isochronous Channels. Ibonelela ngenkqubo ye-algorithmic yokuqinisekisa ukuba izixhobo ezininzi zokwamkela ngaxeshanye zinokufumana idatha kwisixhobo esikhulu. Iprotocol yayo ichaza ukuba isakhelo ngasinye sedatha ethunyelwe yi-Bluetooth transmitter iya kuba nomda wexesha, kwaye idatha efunyenwe sisixhobo sekhoboka emva kwexesha elimiselweyo liya kulahlwa. Oku kuthetha ukuba isixhobo somamkeli sifumana kuphela idatha ngaphakathi kwexesha elivumelekileyo lefestile, ngaloo ndlela iqinisekisa ungqamaniso lwedatha efunyenwe ngamakhoboka amaninzi.
Ukuze uqonde lo msebenzi omtsha, iBluetooth 5.2 yongeza umaleko wokulungelelanisa we-ISOAL (I-Isochronous Adaptation Layer) phakathi kwe-protocol stack Controller kunye ne-Host ukubonelela ngecandelo lokuhamba kwedatha kunye neenkonzo zokuhlengahlengiswa.
Uluhlu lwe-ISOAL luguqula uluhlu oluphezulu lwedatha ye-LE yenkonzo ye-SDU (iyunithi yedatha yeNkonzo) kwidatha yeprotocol yePDU (iyunithi yedatha yeprotocol) efunekayo kwi-baseband transmission kunye vice versa. Umlawuli we-ISOAL wamkela okanye uvelise ii-SDU ngokusebenzisa i-1M exhaswayo kunye ne-2M ye-encoding PHYs. Obona bude buphezulu beSDU nganye yiMax_SDU. Sebenzisa ipakethe yedatha ye-HCI ISO ukuhambisa i-SDU kumaleko aphezulu okanye ukusuka kwinqanaba elisezantsi ukuya emoyeni.
Kwiimeko zesicelo se-LE edibeneyo yemodi kunye nemodi engaxhunywanga, i-Bluetooth 5.2 LE AUDIO protocol ichaza iiseti ezimbini zeemodeli zesikhokelo sokuhanjiswa kwedatha.
