Iyo Bluetooth Special Interest Group (SIG) yakaburitsa chizvarwa chitsva cheBluetooth tekinoroji standard Bluetooth 5.2 LE Audio paCES2020 muLas Vegas. Yakaunza mhepo itsva kunyika yeBluetooth.
Ndeipi misimboti yekufambisa yeiyi tekinoroji nyowani? Kutora chimwe chezvinhu zvayo zvekutanga LE ISOCHRONOUS semuenzaniso, uchitarisira kuti izvi zvinogona kukubatsira kuti udzidze zvakawanda nezve tekinoroji nyowani.
Iyo Bluetooth LE synchronous chiteshi basa inzira nyowani yekufambisa data pakati pemidziyo uchishandisa Bluetooth LE, inonzi LE Isochronous Channels. Iyo inopa algorithmic maitiro ekuona kuti akawanda anogamuchira zvishandiso anogona panguva imwe chete kugamuchira data kubva kune master mudziyo. Protocol yayo inotaura kuti imwe neimwe furemu yedata inotumirwa neBluetooth transmitter ichave neinogumira nguva, uye iyo data inogamuchirwa nemudziyo wevaranda mushure menguva inoraswa. Izvi zvinoreva kuti iyo inogamuchira mudziyo inongogashira data mukati meiyo yakakodzera nguva hwindo, nekudaro ichiva nechokwadi chekuwiriranisa data inogamuchirwa neakawanda evaranda zvishandiso.
Kuti uone basa idzva iri, Bluetooth 5.2 inowedzera ISOAL synchronization adaptation layer (Iyo Isochronous Adaptation Layer) pakati peprotocol stack Controller uye Host kuti ipe data kuyerera segment uye kurongazve masevhisi.
Iyo ISOAL layer inoshandura iyo yepamusoro layer LE sevhisi data SDU (Service data unit) kuita protocol data PDU (protocol data unit) inodiwa pabaseband kutapurirana uye zvichipesana. Iyo ISOAL controller inogamuchira kana kugadzira maSDU kuburikidza neinotsigirwa 1M uye 2M encoding PHYs. Hurefu hwehurefu hweSDU yega yega ndeye Max_SDU. Shandisa HCI ISO data packet kuendesa SDU kune yepamusoro denga kana kubva pazasi denga kuenda kumhepo.
Kune mamiriro ekushandisa e LE yakabatana modhi uye isina-yakabatana modhi, iyo Bluetooth 5.2 LE AUDIO protocol inotsanangura maviri seti yedhata rwizi rwekufambisa yemhando yemhando.
Unoda kudzidza zvakawanda nezve Bluetooth yekubatanidza mhinduro? Ndokumbira ushanyire www.feasycom.com kuti uwane ruzivo.
