Ngokuthuthuka okusheshayo kwe-inthanethi Yezinto, ubuchwepheshe be-Bluetooth bamandla aphansi busetshenziswe kabanzi, futhi ubuchwepheshe bamandla aphansi we-Bluetooth buhlala buphindaphinda, futhi ukusungulwa ngakunye kuyinqubo entsha.Umcabango wobuchwepheshe be-Bluetooth obunamandla aphansi ukuthi busebenzisa amandla amancane.Eqinisweni, isenawo amaphuzu abalulekile olwazi olubandayo.Ake sibheke.
1. I-Bluetooth Low Energy ibuyela emuva iyahambisana ne:
Isibonelo, njengoba i-Bluetooth 5.2 isikhishiwe, futhi uthuthukisa idivayisi esebenzisa ubuchwepheshe be-Bluetooth 5.2, idivayisi ingasebenzisana namadivayisi asebenzisa ubuchwepheshe be-Bluetooth 4.0.Kukhona okuhlukile kulo mthetho, ikakhulukazi uma idivayisi eyodwa isebenzisa izici ozikhethela zona zenguqulo ethile ye-Bluetooth, kodwa ekusebenzeni okuyinhloko, ukucaciswa kuqinisekisa ukuhambisana okubuyela emuva.
2. I-Bluetooth Low Energy ingafinyelela ibanga elingaphezu kwe-1 km:
Incazelo yasekuqaleni yobuchwepheshe be-Bluetooth obunamandla aphansi impela amandla aphansi, ukudluliselwa kwebanga elifushane.Kodwa imodi entsha ebizwa nge-Long Range Mode (Coded PHY) yethulwe nge-Bluetooth 5.0, evumela amadivaysi e-BLE ukuthi axhumane ngobubanzi obude, kufikela ku-1.5 km womugqa wokubona.
3. Ubuchwepheshe bamandla aphansi be-Bluetooth busekela iphoyinti-kuya-iphuzu, inkanyezi ne-mesh topology:
Ubuchwepheshe bamandla aphansi e-Bluetooth bungobunye bobuchwepheshe obungenawaya obunamandla aphansi obungamela izinhlobo ezihlukahlukene zezihloko zezinhlelo zokusebenza eziningi ezahlukene.Ngokwemvelo isekela ukuxhumana kontanga kuya kontanga, okufana phakathi kwe-smartphone nesilandeleli sokufaneleka.Ukwengeza, isekela i-topology eyodwa kuya kweziningi, njengehabhu le-Bluetooth Low Energy elixhumanisa namadivayisi amaningi ahlakaniphile ekhaya ngesikhathi esisodwa.Ekugcineni, ngokwethulwa kokucaciswa kwe-Bluetooth mesh ngoJulayi 2017, i-BLE iphinde isekele ama-topology amaningi kuya kwabaningi (i-mesh).
4. Iphakethe lokukhangisa lamandla aphansi we-Bluetooth liqukethe amabhayithi angama-31 edatha:
Lona usayizi ojwayelekile wenkokhelo yokukhangisa yamaphakethe athunyelwe eziteshini eziyinhloko zokukhangisa (37, 38, kanye 39).Kodwa-ke, khumbula ukuthi lawo mabhayithi angama-31 azofaka okungenani amabhayithi amabili: eyodwa ubude neyodwa yohlobo.Kusele amabhayithi angu-29 kudatha yomsebenzisi.Futhi, khumbula ukuthi uma unezinkambu eziningi ezinezinhlobo zedatha yezikhangiso ezihlukile, uhlobo ngalunye luzothatha amabhayithi amabili engeziwe ngobude nohlobo.Emaphaketheni okukhangisa athunyelwe esiteshini sesibili sokukhangisa (ethulwe nge-Bluetooth 5.0), inani elikhokhelwayo liyakhuphuka libe ngamabhayithi angu-254 esikhundleni samabhayithi angu-31.
