Izalathisi eziphambili zokuSebenza zeBluetooth iiModyuli zaMandla aPhantsi
Njengobuchwephesha bonxibelelwano obudumileyo kwi-Intanethi yezicelo zeZinto, amandla aphantsi eBluetooth asetyenziswa kakhulu kwikhaya elikrelekrele, izixhobo ezinxitywayo ezikrelekrele, izixhobo zombane zabathengi, ukhathalelo lwezonyango olukrelekrele kunye nokhuseleko kunye nezibonelelo zokusetyenziswa kwamandla aphantsi kunye nokulibaziseka okuphantsi. Ngokwandiswa okuqhubekayo kwe-Bluetooth-low-power applications, zeziphi izikhombisi zokusebenza kufuneka ziqwalaselwe xa ukhetha iimodyuli zeBluetooth zamandla aphantsi? Yeyiphi imisebenzi yezi zalathi? Jonga nge Umenzi wemodyuli yeBluetooth edibeneyo
Iimpawu zokusebenza eziphambili zemodyuli yeBluetooth yamandla aphantsi
1. I-Chip
Itshiphu imisela amandla ombane wemodyuli yeBluetooth, kwaye ukusebenza kwetshiphu kumisela ngokuthe ngqo ukusebenza kwemodyuli yonxibelelwano engenazingcingo. Imodyuli ye-Joinet yamandla aphantsi yeBluetooth isebenzisa iitshiphusi ezivela kubenzi be-chip beBluetooth abaziwayo kumazwe ngamazwe, kwaye ukusebenza kwemveliso kuqinisekisiwe.
2. Ukusetyenziswa kwamanzi
Ixabiso lokusetyenziswa kwamandla kwinguqu nganye yemodyuli ye-Bluetooth yamandla aphantsi ahlukile, kwaye ixabiso lokusetyenziswa kwamandla enguqu ye-5.0 liphantsi. Ngoko ke, ukuba imveliso ineemfuno kwixabiso lokusetyenziswa kwamandla kwisicelo, i-5.0 version kufuneka ithathelwe ingqalelo kuqala. Abavelisi bemodyuli edibeneyo yeBluetooth baphuhlisa kwaye bavelise iintlobo ezahlukeneyo zeemodyuli zamandla aphantsi ukukhetha kuzo.
3. Umxholo wothumelo
Imodyuli yeBluetooth yamandla aphantsi yimodyuli yeBluetooth yokuhanjiswa kwedatha exhasa kuphela ukuhanjiswa kwedatha. Izakhono zothumelo lwedatha yeenguqulelo ezahlukeneyo zahluke kakhulu. Ngokubhekiselele kwintlawulo yosasazo, imodyuli ye-5.0 yenguqulo ngamaxesha e-8 yemodyuli ye-4.2 yenguqulo, ngoko kufuneka isekelwe kwimveliso yesicelo Iimfuno zangempela zokukhetha imodyuli yokukhetha.
4. Izinga losulelo
Inguqulelo yeBluetooth ephindaphindwayo inokwanda okuhambelanayo kwireyithi yothumelo. Ukuba ufuna imodyuli yeBluetooth enesantya sothumelo olukhawulezayo, unokukhetha imodyuli yeBluetooth 5.0 kuqala.
5. Umgama wothumelo
Umgama osebenzayo wethiyori weBluetooth 5.0 unokufikelela kwiimitha ezingama-300. Ke ngoko, ukuba ufuna ukuqonda unxibelelwano lweBluetooth kumgama omde kancinane, ungakhetha imodyuli yeBluetooth 5.0.
6. Ujongano
Ngokuxhomekeke kwiimfuno zemisebenzi ethile ephunyeziweyo kujongano, ujongano lwemodyuli yeBluetooth yahlulwe kujongano lweUART, izibuko leGPIO, izibuko leSPI kunye I.²C port, kwaye ujongano ngalunye lunokuqonda imisebenzi eyahlukeneyo ehambelanayo. Ukuba lugqithiso lwedatha nje, kulungile ukusebenzisa i-serial interface (inqanaba leTTL).
7. Ubudlelwane benkosi-khoboka
Imodyuli eyintloko inokukhangela ngokusebenzayo kwaye idibanise ezinye iimodyuli zeBluetooth kunye nenqanaba elifanayo okanye elisezantsi lenguqulo yeBluetooth njengayo ngokwayo; imodyuli yekhoboka ilinde ngokuzimeleyo abanye ukuba bakhangele kwaye badibanise, kwaye inguqulo yeBluetooth kufuneka ifane nayo okanye iphezulu. Izixhobo ezihlakaniphile eziqhelekileyo kwiimarike zikhetha imodyuli yekhoboka, ngelixa imodyuli yenkosi isetyenziswa ngokubanzi kwiifowuni eziphathwayo kunye nezinye izixhobo ezinokusetyenziswa njengeziko lolawulo.
8. I-antenna
Iimveliso ezahlukeneyo zineemfuno ezahlukeneyo zee-eriyali. Okwangoku, ii-eriyali ezisetyenziswa ngokuqhelekileyo kwiimodyuli zeBluetooth ziquka ii-eriyali zePCB, ii-eriyali ze-ceramic, kunye ne-IPEX yangaphandle. Ukuba zifakwe ngaphakathi kwendawo yokuhlala yesinyithi, khetha ngokubanzi imodyuli yeBluetooth ene-eriyali yangaphandle ye-IPEX.
Joinet, njengengcali umenzi wemodyuli yeBluetooth , inokubonelela abathengi ngeentlobo ezahlukeneyo zeemodyuli zamandla aphantsi eBluetooth. Ukuba uneemfuno ezikhethekileyo, unokuqhagamshelana nathi ukuze wenze ngokwezifiso imveliso okanye iinkonzo zophuhliso.
