Njengoba sazi, imojula ye-Bluetooth ihlukaniswe yaba izinhlobo ezimbili: I-Bluetooth Yakudala (BR/EDR) ne-Bluetooth Low Energy (BLE). Kunamaphrofayili amaningi e-Classic Bluetooth ne-BLE: i-SPP, i-GATT, i-A2DP, i-AVRCP, i-HFP, njll. Ngokudluliswa kwedatha, i-SPP ne-GATT amaphrofayili e-Classic Bluetooth ne-BLE asetshenziswa kakhulu ngokulandelana.
Ithini iphrofayela ye-SPP?
I-SPP (Serial Port Profile) iphrofayili ye-Bluetooth Yakudala, i-SPP ichaza izimfuneko zamadivayisi e-Bluetooth adingekayo ukuze kumiswe ukuxhunywa kwekhebula le-serial okulingiswayo kusetshenziswa i-RFCOMM phakathi kwamadivaysi kontanga amabili. Izidingo zivezwa ngokwamasevisi ahlinzekwa ezinhlelweni zokusebenza, nangokuchaza izici nezinqubo ezidingekayo ukuze zisebenzisane phakathi kwamadivaysi e-Bluetooth.
Ithini iphrofayela ye-GATT?
I-GATT (iphrofayili ye-Generic Attribute iphrofayili ye-BLE, ichaza imininingwane yemishini emibili ye-BLE ukuxhumana nge-Service and Characteristic, izinhlangothi ezimbili zokuxhumana ze-GATT ubudlelwano beKlayenti/Iseva, I-Peripheral iyiseva ye-GATT, Emaphakathi yiKlayenti le-GATT, konke ukuxhumana , zombili ziqalwa Iklayenti, futhi zithola impendulo Kuseva.
Inhlanganisela ye-SPP+GATT
I-SPP kanye ne-GATT badlala indima yokudlulisa idatha, kufanele siqaphele ukuthi lapho sisebenzisa imojula ye-Bluetooth ukuxhumana nohlelo lokusebenza lweselula, ku-smartphone ye-iOS, i-BLE (GATT) ukuphela kwephrofayili yokudlulisela idatha yezindlela ezimbili esekelwe mahhala sebenzisa, ku-smartphone ye-Android, isekela kokubili i-SPP ne-GATT, ngakho-ke ibaluleke kangakanani imojula isekela kokubili i-SPP ne-GATT.
Uma imojuli ye-Bluetooth isekela kokubili i-SPP ne-GATT, kusho ukuthi iyimojuli ye-Bluetooth yemodi ekabili. Yimaphi amamojula anconyiwe emodi ekabili ye-Bluetooth?
Lawa mamojula amabili awalulungele uhlelo lwakho lokusebenza? Ungangabazi ukuxhumana ne-Feasycom manje!
