Gulu la Bluetooth Special Interest Group (SIG) latulutsa m'badwo watsopano waukadaulo waukadaulo wa Bluetooth Bluetooth 5.2 LE Audio ku CES2020 ku Las Vegas. Zinabweretsa mphepo yatsopano kudziko la Bluetooth.
Kodi njira yaukadaulo yatsopanoyi ndi yotani? Kutengera chimodzi mwazinthu zake zazikulu LE ISOCHRONOUS mwachitsanzo, ndikuyembekeza izi zitha kukuthandizani kuphunzira zambiri zaukadaulo watsopano.
Bluetooth LE synchronous channel function ndi njira yatsopano yosamutsira deta pakati pa zipangizo pogwiritsa ntchito Bluetooth LE, yotchedwa LE Isochronous Channels. Imapereka njira ya algorithmic kuti iwonetsetse kuti zida zambiri zolandila zitha kulandira nthawi imodzi kuchokera ku chipangizo chachikulu. Protocol yake imanena kuti chimango chilichonse cha data chomwe chimatumizidwa ndi transmitter ya Bluetooth chizikhala ndi malire a nthawi, ndipo zomwe zidalandilidwa ndi chipangizo chaukapolo pambuyo pa nthawiyo zidzatayidwa. Izi zikutanthauza kuti chipangizo cholandirira chimangolandira deta mkati mwa zenera lovomerezeka la nthawi, potero zimatsimikizira kulumikizana kwa data yomwe idalandilidwa ndi zida zingapo za akapolo.
Kuti muzindikire ntchito yatsopanoyi, Bluetooth 5.2 imawonjezera kusanja kwa ISOAL synchronization adaptation (The Isochronous Adaptation Layer) pakati pa Protocol stack Controller ndi Host kuti apereke magawo akuyenda kwa data ndi kukonzanso ntchito.
Chigawo cha ISOAL chimatembenuza gawo lapamwamba la LE service data SDU (Service data unit) kukhala protocol data PDU (protocol data unit) yofunikira pakutumiza kwa baseband ndi mosemphanitsa. Woyang'anira ISOAL amavomereza kapena kupanga ma SDU kudzera mu ma PHY othandizidwa ndi 1M ndi 2M. Kutalika kwakukulu kwa SDU iliyonse ndi Max_SDU. Gwiritsani ntchito paketi ya data ya HCI ISO kuti mutumize SDU kumtunda wapamwamba kapena kuchokera pansi kupita kumlengalenga.
Pamawonekedwe ogwiritsira ntchito LE olumikizidwa mode komanso osalumikizidwa, protocol ya Bluetooth 5.2 LE AUDIO imatchula mitundu iwiri yamitundu yotumizira ma data.
Ndikufuna kudziwa zambiri za Mayankho olumikizana ndi Bluetooth? Chonde pitani www.feasycom.com kuti mudziwe zambiri.
