Ithimba labacwaningi abavela eNyuvesi yaseCalifornia, e-San Diego, lenze indlela yokuhlonza amadivaysi eselula kusetshenziswa amabhakhoni athunyelwa emoyeni kusetshenziswa i-Bluetooth Low Energy (BLE) futhi esetshenziswa izamukeli ze-Bluetooth ezingenzi lutho ukuthola amadivayisi amasha phakathi nobubanzi.
Kuye ngokusetshenziswa, amasiginali webhakhoni athunyelwa nemvamisa yezikhathi ezingaba ngu-500 ngomzuzu futhi, njengoba kucatshangwa abadali bezinga, awanawo wonke umuntu futhi awakwazi ukusetshenziselwa ukubophezela kumsebenzisi. Eqinisweni, isimo sivele sihlukile futhi lapho sithunyelwa, isignali ihlanekezelwa ngaphansi kwethonya lezici eziphakama ngesikhathi sokukhiqizwa kwe-chip ngayinye. Lokhu kuhlanekezela, okuhlukile futhi okungaguquki kudivayisi ngayinye, kungatholwa kusetshenziswa ama-transceivers ahlelekayo ajwayelekile (SDR, Software Defined Radio).
Inkinga izibonakalisa kuma-chips ahlanganisiwe ahlanganisa ukusebenza kwe-Wi-Fi ne-Bluetooth, sebenzisa i-oscillator eyinhloko evamile kanye nezingxenye eziningana ezisebenzayo ze-analog, izici zazo eziholela ku-asymmetry esigabeni kanye nobukhulu. Izindleko zemishini yokwenza lokhu kuhlasela zilinganiselwa ku-$200. Izibonelo zekhodi zokukhipha amalebula ahlukile kusiginali ebanjiwe zishicilelwa ku-GitHub.
Empeleni, isici esikhonjiwe sivumela idivayisi ukuthi ikhonjwe, ngokunganaki ukusetshenziswa kwezinyathelo zokuvikela ukuhlonza njengokungahleliwe kwekheli le-MAC. Ku-iPhone, ibanga lokwamukela umaka elanele ukuhlonzwa lalingamamitha ayi-7, nohlelo lokusebenza lokulandelela othintana naye lwe-COVID-19 lusebenza. Kumadivayisi e-Android, ukuhlonza kudinga ukusondelana.
Ukuqinisekisa ukusebenza kahle kwendlela ukusebenza, ukuhlolwa okuningana kwenziwa ezindaweni zomphakathi njengamakhefi. Ngesikhathi sokuhlolwa kokuqala, kwahlaziywa amadivaysi angu-162, okuyizihlonzi ezihlukile ezakhiwe ngama-40%. Ocwaningweni lwesibili, amadivaysi eselula angama-647 ahlolisiswa, futhi izihlonzi ezihlukile zenzelwe u-47% wazo. Ekugcineni, ithuba lokusebenzisa izihlonzi ezikhiqiziwe ukulandelela ukunyakaza kwamadivayisi amavolontiya avumile ukubamba iqhaza ekuhlolweni abonisiwe.
Abacwaningi baphinde baphawula izinkinga ezimbalwa ezenza kube nzima ukuhlonza. Isibonelo, amapharamitha wesignali yebhakhoni athintwa izinguquko kuzinga lokushisa, hhayi ibanga lapho ithegi yamukelwe khona ithintwa ushintsho kumandla esignali ye-Bluetooth esetshenziswa kwamanye amadivaysi. Ukuze uvimbele indlela yokuhlonza okukhulunywa ngayo, kuhlongozwa ukuthi kuhlungwe isignali ezingeni le-firmware le-chip ye-Bluetooth noma kusetshenziswe izindlela ezikhethekile zokuvikela ihadiwe. Ukukhubaza i-Bluetooth akwanele, njengoba amanye amadivaysi (isibonelo, ama-smartphones e-Apple) aqhubeka nokuthumela amabhakhoni ngisho nalapho i-Bluetooth icishiwe futhi idinga ukuvala shaqa okuphelele kwedivayisi ukuze uvimbele ukuthumela.
