Ngezantsi, i Umenzi wemodyuli yeBluetooth edibeneyo ishwankathela izinto ezilishumi ezichaphazela umsebenzi wemodyuli yeBluetooth kwireferensi yakho.
Imiba elishumi echaphazela uMsebenzi weBluetooth Modyuli
1. Ukusetyenziswa kwamanzi
IBluetooth yahlulwe ngokweBluetooth yemveli kunye neBluetooth Low Energy (BLE). Izixhobo ezihlakaniphile ezisebenzisa iimodyuli zeBluetooth zemveli ziqhawulwa rhoqo, zifuna ukubhanqa okuphindaphindiweyo, kwaye ibhetri iya kuphelelwa ngokukhawuleza. Izixhobo ezihlakaniphile zisebenzisa iimodyuli zeBluetooth ezinamandla aphantsi Isebenza ixesha elide kwibhetri enye iqhosha. Ngoko ke, ukuba sisixhobo esihlakaniphile esinebhetri esine-wireless, kungcono ukhethe i-Bluetooth 5.0/4.2/4.0 imodyuli yeBluetooth enamandla aphantsi ukuqinisekisa ubomi bebhetri bemveliso. Iimodyuli zeBluetooth ezinamandla aphantsi eziphuhliswe kwaye ziveliswe ngabavelisi bemodyuli ye-Joint Bluetooth baneempawu zokusetyenziswa kwamandla aphantsi, ukuchasana nokuphazamiseka, ubungakanani obuncinci, umgama omde, kunye neendleko eziphantsi.
2. I-Chip
Itshiphu imisela amandla ekhompyutha emodyuli yeBluetooth. "Isiseko" esinamandla sisiqinisekiso samandla emodyuli yeBluetooth. Abavelisi betshiphu abaziwayo kumazwe ngamazwe beBLE baquka iNordic, Dialog, kunye neTI.
3. Ujongano
I-interface yemodyuli yeBluetooth yahlulwe kwi-serial interface, i-interface ye-USB, i-port ye-IO yedijithali, i-analog IO port, i-SPI programming port kunye ne-interface yezwi, kwaye ujongano ngalunye lunokuqonda imisebenzi eyahlukeneyo ehambelanayo. Imodyuli yeBluetooth ehambelanayo inokukhethwa ngokweemfuno zemveliso.
4. Umgama wothumelo
Khetha imodyuli ehambelanayo ngokweemfuno zemveliso kumgama wothumelo, njengee-earphones ezingenazingcingo, iimpuku ezingenazingcingo, njl., Ukuba umgama wokuhambisa awukho phezulu, ungakhetha imodyuli yeBluetooth ngomgama omfutshane wokuhambisa, kunye neemveliso. ezineemfuno ezithile kumgama wothumelo, kufuneka ukhethe imodyuli ehambelanayo. Imodyuli yeBluetooth ehambelana nomgama wothumelo.
5. 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.
6. 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.
7. Izinga losulelo
Xa ukhetha imodeli yemodyuli yeBluetooth, izinga lokuhanjiswa kwedatha efunekayo phantsi kwendawo yokusebenza yemveliso kufuneka ithathwe njengomgangatho wereferensi, kwaye umahluko kwizinga lokuhambisa unquma imeko yesicelo semveliso.
8. Dlulisa umxholo
Imodyuli yeBluetooth inokudlulisa idatha kunye nolwazi lwezwi ngaphandle kwamacingo, kwaye yahlulwe kwimodyuli yedatha yeBluetooth kunye nemodyuli yezwi yeBluetooth ngokwemisebenzi. Imodyuli yedatha yeBluetooth isetyenziselwa ukuhanjiswa kwedatha, ilungele ulwazi kunye nokuhanjiswa kwedatha kwiindawo zikawonkewonke ezinetrafikhi enkulu njengemiboniso, izitishi, izibhedlele, izikwere, njl.; imodyuli yelizwi yeBluetooth inokudlulisa ulwazi lwelizwi, kwaye ifanelekile kunxibelelwano phakathi kweefowuni zeBluetooth kunye neeseti zeBluetooth. Ukuhanjiswa komyalezo welizwi.
9. Iindleko ezisebenzayo
Ixabiso liyinkxalabo enkulu kubavelisi xa bekhetha iimodyuli zeBluetooth. Njengoshishino lwelizwe lobuchwepheshe obuphezulu, i-Joinet ibandakanyeke ngokunzulu kwintsimi yeemodyuli ze-IoT iminyaka engaphezu kweshumi, kwaye inokubonelela abavelisi ngeemodyuli zeBluetooth ezinexabiso eliphantsi kunye nezisombululo. Akuyomfuneko ukukhetha eyona modyuli yeBluetooth enamandla aphantsi, kodwa kufuneka ukhethe eyona ifanelekileyo kwaye ineendleko ezifanelekileyo.
10. Ifomu yephakheji
Kukho iintlobo ezintathu zeemodyuli zeBluetooth: uhlobo lomgca, uhlobo lokunyuka komphezulu kunye ne-adapter ye-serial port. Uhlobo lwe-in-line lunezikhonkwane ze-pin, ezilungele ukuthengiswa kwangaphambili kwaye zifanelekile kwimveliso encinci ye-batch; imodyuli ye-surface Mount isebenzisa iipads ze-semicircular njengezikhonkwane, ezifanelekileyo kwimveliso yokuthengisa i-mass reflow yokuthengisa abathwali abancinci; i-adaptha ye-serial yeBluetooth isetyenziselwa Xa kungenakulungeleka ukwakha iBluetooth kwisixhobo, inokuqhagamshelwa ngokuthe ngqo kwi-nine-pin serial port yesixhobo, kwaye ingasetyenziswa emva kokuvulwa kombane. Iindidi ezahlukeneyo zeemodyuli kufuneka zikhethwe ngokufanelekileyo ngokwesakhiwo semveliso.
Ukuba ufuna ukwazi iinkcukacha ezithe vetshe malunga neBluetooth Low Energy module, nceda uqhagamshelane nomvelisi wemodyuli yeBluetooth yeJoyineli. I-Joinet ineminyaka emininzi yamava ophando kwiimodyuli zamandla aphantsi eBluetooth.
