Kunezinhlobo ezahlukene zokuxhuma ezitholakalayo kudivayisi ye-BLE. Into exhunyiwe ye-BLE ingase ibe nemisebenzi emi-4 ehlukene:
1. Umsakazi
"Umsakazi" uzosetshenziswa njengeseva. Ngakho-ke, inhloso yakho ukudlulisa idatha kudivayisi njalo, kodwa ayisekeli noma yikuphi ukuxhumana okungenayo.
Isibonelo esijwayelekile i-Beacon esekelwe ku-Bluetooth Low Energy. Uma ibhekhoni ikumodi yokusakaza, ngokuvamile isethwe kusimo esingaxhumeki. I-Beacon izosakaza iphakethe ledatha endaweni ezungezile ngezikhathi ezithile. Njengosokhaya ozimele we-Bluetooth, izothola ukusakazwa kwe-Beacon ngezikhathi ezithile lapho yenza izenzo zokuskena Ngaphandle kwephakethe. Okuqukethwe kwephakethe kungaqukatha kufika kumabhayithi angu-31 wokuqukethwe. Ngesikhathi esifanayo, lapho umsingathi ethola iphakethe lokusakaza, lizobonisa ikheli le-MAC, Inkomba Yamandla Esiginali Etholiwe (RSSI), kanye nedatha ethile yokukhangisa ehlobene nohlelo lokusebenza. Isithombe esingezansi yi-Feasycom BP103: I-Bluetooth 5 Mini Beacon
2. Umbukeli
Esinyathelweni sesibili, idivayisi ingaqapha futhi ifunde idatha ethunyelwe "umsakazi". Esimeni esinjalo, into ayikwazi ukuthumela noma yikuphi ukuxhumana kuseva.
Isibonelo esijwayelekile yiGateway. I-BLE Bluetooth ikumodi yokubuka, akukho kusakazwa, ingaskena izinto ezisetshenziswayo zokusakaza ezizungezile, kodwa ayikwazi ukudinga ukuxhumana nezinto zokusakaza. Isithombe esingezansi yi-Feasycom Gateway BP201: I-Bluetooth Beacon Gateway
3. Maphakathi
I-Central ngokuvamile iqukethe i-smartphone noma ithebhulethi. Le divayisi inikeza izinhlobo ezimbili ezihlukene zokuxhuma: kungaba kumodi yokukhangisa noma kumodi exhunyiwe. Ihola inqubo yonke njengoba icupha ukudluliswa kwedatha. Isithombe esingezansi yi-Feasycom BT630, esekelwe ku-nRF52832 chipset, isekela izindlela ezintathu: i-central, peripheral, central-peripheral. Usayizi Omncane we-Bluetooth Module nRF52832 Chipset
4. I-peripheral
Idivayisi yocingo ivumela ukuxhumana nokudluliswa kwedatha ne-Central ngezikhathi ezithile. Umgomo walolu hlelo uwukuqinisekisa ukudluliswa kwedatha yonke indawo ngokusebenzisa inqubo evamile, ukuze nezinye izisetshenziswa zifunde futhi ziqonde idatha.
Imojula ye-Bluetooth Low Energy esebenza kumodi ye-peripheral nayo isesimweni sokusakaza, ilindele ukuskenwa. Ngokungafani nemodi yokusakaza, imojula ye-Bluetooth kumodi yesigqila ingaxhunywa, futhi isebenze njengesigqila ngesikhathi sokudluliswa kwedatha.
Iningi lamamojula ethu e-BLE angasekela imodi emaphakathi ne-peripheral. Kodwa sine-firmware esekela i-peripheral-only mode, isithombe esingezansi yi-Feasycom BT616, ine-firmware esekela imodi ye-peripheral-only: BLE 5.0 Module TI CC2640R2F Chipset
