Kutheni iModyuli yeBluetooth yeClassic ingakwazi ukuSebenzisa ukuSetyenziswa kwamandla aphantsi?
Ukuvela kwemodyuli yebluetooth yamandla aphantsi kuye kwaphucula iintsilelo zeemodyuli zebluetooth zakudala kwaye ibe yinkqubo esemgangathweni yee-smartphones eziphezulu. Imodyuli ye-BLE + ikhaya elilumkileyo, yenza ubomi bethu bube krelekrele.
Kutheni imodyuli yeBluetooth yakudala ingakwazi ukufikelela kusetyenziso lwamandla aphantsi?
Makhe sijonge iimpawu zeBluetooth imodyuli yamandla aphantsi kunye nomenzi wemodyuli yeBluetooth Joinet:
1: Ukusetyenziswa kwamandla aphantsi
Ukunciphisa ukusetyenziswa kwamandla, izixhobo zamandla aphantsi eBluetooth zichitha ixesha lazo elininzi kwimowudi yokulala. Xa umsebenzi usenzeka, isixhobo sivuka ngokuzenzekelayo kwaye sithumele umyalezo obhaliweyo kwisango, i-smartphone okanye iPC. Awona mandla aphezulu/incopho yokusetyenziswa kwamandla akudluli kwi-15mA. Ukusetyenziswa kwamandla ngexesha lokusetyenziswa kuncitshiswe ukuya kwisinye kwishumi sezixhobo zeBluetooth eziqhelekileyo. Kwisicelo, ibhetri yeqhosha linokugcina ukusebenza okuzinzileyo iminyaka eliqela.
2: Ukuzinza, uKhuseleko kunye nokuthembeka
Itekhnoloji yeBluetooth Low Energy isebenzisa ubuchwephesha obufanayo be-Adaptive Frequency Hopping (AFH) njengobuchwepheshe beBluetooth obuqhelekileyo, ngaloo ndlela iqinisekisa ukuba iimodyuli zeBluetooth Low Energy zinokugcina uthumelo oluzinzileyo kwindawo yeRF "enengxolo" kwiindawo zokuhlala, kwimizi-mveliso nakwizicelo zonyango. Ukunciphisa iindleko kunye nokusetyenziswa kwamandla okusebenzisa i-AFH, iteknoloji yeBluetooth Low Energy inciphise inani letshaneli ukusuka kuma-79 1 MHz amajelo abanzi obuchwepheshe beBluetooth obuqhelekileyo ukuya kuma-40 2 MHz amajelo abanzi.
3: Ukuhlalisana ngocingo
Itekhnoloji yeBluetooth isebenzisa i-2.4GHz ISM frequency band engadingi layisensi. Ngobugcisa obuninzi bokwabelana ngesi sithuba se-airwave, ukusebenza kweengcingo kunengxaki yokulungiswa kweempazamo kunye nokuhanjiswa kwakhona okubangelwa luphazamiseko (umzekelo, ukunyuka kwe-latency, ukucuthwa kokuhamba, njl. njl.). Kwizicelo ezifunwayo, ukuphazamiseka kunokuncitshiswa ngokucwangcisa amaza kunye noyilo olukhethekileyo lwe-antenna. Ngenxa yokuba zombini imodyuli yeBluetooth yendabuko kunye nemodyuli yeBluetooth yamandla aphantsi isebenzisa i-AFH, itekhnoloji enokunciphisa ukuphazamiseka kobunye ubugcisa berediyo, ukuhanjiswa kweBluetooth kunozinzo olugqwesileyo kunye nokuthembeka.
4: Uluhlu loqhagamshelwano
Ukumodareyithwa kwetekhnoloji yamandla aphantsi eBluetooth yahluke kancinane kuleyo yobuchwepheshe beBluetooth bemveli. Oku kumodareyitha okuhlukeneyo kwenza uluhlu loqhagamshelwano ukuya kuthi ga kwiimitha ezingama-300 kwi-chipset engenazingcingo ye-10 dBm (iBluetooth Low Energy ubuninzi bamandla).
I-5: Ukusetyenziswa ngokulula kunye nokudibanisa
Ipiconet yamandla aphantsi eBluetooth idla ngokusekwe kwisixhobo esiqhagamshelwe kwizixhobo ezininzi zamakhoboka. Kwi-piconet, zonke izixhobo zingabaphathi okanye amakhoboka, kodwa azikwazi ukuba ngabaphathi kunye namakhoboka ngaxeshanye. Isixhobo esiyintloko silawula ukuphindaphindeka konxibelelwano lwesixhobo sekhoboka, kwaye isixhobo sobukhoboka sinokunxibelelana kuphela ngokweemfuno zesixhobo esiyintloko. Xa kuthelekiswa netekhnoloji yeBluetooth yemveli, umsebenzi omtsha owongeziweyo ngeBluetooth yamandla aphantsi ubuchwepheshe ngumsebenzi "wosasazo". Ngeli nqaku, isixhobo sekhoboka sinokubonisa ukuba kufuneka sithumele idatha kwisixhobo esiyintloko.
Kuba ukumodareyitha komgangatho womzimba kunye neendlela zokuthotywa kweBluetooth yakudala kunye neBluetooth enamandla aphantsi zahlukile, izixhobo zeBluetooth ezinamandla aphantsi kunye nezixhobo zeBluetooth zakudala azikwazi ukunxibelelana. Ukuba isixhobo esiyintloko sisixhobo seBluetooth esine-low-power, isixhobo sekhoboka kufuneka kwakhona sibe sisixhobo seBluetooth esinamandla aphantsi; ngokufanayo, isixhobo ikhoboka Bluetooth zakudala ukunxibelelana kuphela isixhobo master classic Bluetooth.
I-Joinet, njengophando kunye nophuhliso kunye nomvelisi weemodyuli zeBluetooth ezinamandla aphantsi, ngaphezu kweemodyuli zeBluetooth ezinamandla aphantsi, sikwanazo nezisombululo ezihambelanayo, ezifana nezi: iibhulashi zamazinyo ezihlakaniphile, izicoci zamanzi zenethiwekhi, njl. Wamkelekile ukudibana!
