Izinkinga ezivamile ekusebenziseni isibhamu sokuskena se-Bluetooth

Izinkinga ezijwayelekile ekusebenziseni isibhamu sokuskena se-Bluetooth

Inkokhelo yeselula izongenisa abantu enkathini yokuba lula nelula, ngakho-ke i-2d ibhakhodi scan gun izokwenza isiqinisekiso esiyisisekelo senkathi ye-inthanethi yeselula. Ezimpilweni zethu, kungakhathaliseki ukuthi zisemigwaqweni noma ezinxanxatheleni zezitolo, izitolo eziningi zizosebenzisa isibhamu sokuskena ikhodi ye-QR, esesiphenduke ummeleli wenkathi yokukhokha yeselula ngokungazi. Futhi abaqalayo bazohlangabezana nezinkinga eziningi ezisetshenziswayo. Namuhla, i-Vista ikuyisa ukuthi ufunde futhi uzame ukuxazulula lezi zinkinga ezivamile.

1. Uma i-isibhamu sokuskena se-Bluetooth ingasebenzi, ulayini wokukhanya uhlala uvuliwe.

Ukuhlaziywa kwesizathu: ngephutha setha ukukhanya kuhlale kusesimweni.

Isixazululo: buyisela izilungiselelo zasefekthri futhi ucime ukukhanya okuvamile.

2. Isibhamu sokuskena se-Bluetooth uma ukuskena ukukhanya kwe-LED kungakhanyi, futhi kungekho mpendulo?

Ukuhlaziywa kwesizathu: kungenzeka ukuthi ukunikezwa kwamandla kwe-isibhamu sokuskena se-Bluetooth akuxhunyiwe, noma isixhumi esibonakalayo Ikhebula ledatha alixhunywanga ngokuqinile, okubangela ukuthintana okungalungile.

Isixazululo: qala uhlole ukuthi ingabe amandla esibhamu sokuskena sekhodi enezinhlangothi ezimbili axhunyiwe. Uma ixhunyiwe, hlola ukuthi ingabe ukuxhumana komugqa wedatha kukhululekile yini. Kungcono ukuphinda uxhume ulayini wedatha kanye nesibhamu sokuskena sekhodi enezinhlangothi ezimbili ukuze uqinisekise amandla avamile avuliwe.

3. Ngemuva kokuthi i-Isibhamu sokuskena ikhodi ye-QR ixhunyiwe, i-LED ikhanya ngaso sonke isikhathi, futhi awukho umsindo, futhi ayikwazi ukuskena?

Ukuhlaziya imbangela: kungase kube inkinga yangaphakathi yokuskena isibhamu, ngokuvamile i-IC ayixhumani kahle.

Isixazululo: kulokhu, sicela uthole umdayisi noma umkhiqizi ozolungiswa.

4. Ukuskena isibhamu kuqala ngokujwayelekile, futhi i-laser iyavela, kodwa ayifundi ikhodi?

Ukuhlaziywa kwembangela: kunezizathu eziningi zale nkinga. Okokuqala ukuthi uhlelo lwekhodi yebha luvaliwe; Okwesibili kungenzeka ukuthi ibhakhodi yonakalisiwe; Okwesithathu kungenzeka ukuthi ikhodi yebha inezinkinga zekhwalithi, okungukuthi, ukuphrinta ikhodi yebha akuhlangabezani nezinga; Okwesine, ukuthi i-lens evikela uthuli ihlanzekile yini; Okwesihlanu okungenzeka ukuthi ihadiwe yesibhamu sokuskena noma ibhodi lomama liyahluleka.

Isixazululo: okokuqala, ungavula uhlelo oluhambisanayo lwekhodi yebha, bese uhlola ukuthi ibhakhodi yonakele yini.

5. Imbobo yembobo ewuchungechunge yesibhamu sokuskena ixhunyiwe, kodwa akukho ukudluliswa kwedatha uma ufunda ikhodi?

Ukuhlaziywa kwesizathu: kungenzeka ukuthi imodi yembobo yochungechunge yesibhamu sokuskena ayisethiwe,

Isixazululo: ngokwemanyuwali, setha isibhamu sokuskena sibe yimodi yembobo ye-serial.

6. Uma isibhamu sokuskena siskena ibhakhodi, ibhiphu ijwayelekile, kodwa akukho ukudluliswa kwedatha?

Ukuhlaziywa kwesizathu: kungenzeka ukuthi isibhamu sokuskena asisethwanga ngendlela efanele, okuholela ekungadlulisweni kwedatha yesibhamu esiskena. Esinye isizathu kungaba ukuthi intambo yokudlulisela ihluleka, okuholela ekungadluliswani kwedatha.

Isixazululo: izilungiselelo zasefekthri zingabuyiselwa, futhi isibhamu sokuskena ikhodi ye-QR singasethwa kabusha ngokuvumelana nebhukwana ukuze kuqinisekiswe ukuthi izilungiselelo zomugqa wedatha ezihambisanayo. zilungile.

7. Kungani amanye amabhakhodi esibhamu sokuskena engaskenwa futhi amanye amabhakhodi awakwazi ukuskenwa?

Ukuhlaziywa kwesizathu: okokuqala, isistimu yekhodi yebhakhodi ayihlangabezani nezidingo zesithwebuli sekhodi enezinhlangothi ezimbili; okwesibili, isithwebuli asiyisebenzisi ibhakhodi; okwesithathu, ibhakhodi yonakele. Okwesine okungenzeka ukwehluleka kwehadiwe.

Isixazululo: buyisela izilungiselelo zasefekthri, bheka imanuwali ukuze uvule uhlelo lwekhodi yebha, noma ubuyisele ibhakhodi.

Ngokusebenzisa isisombululo senkinga yesibhamu sokuskena ngekhodi enezinhlangothi ezimbili, bangane. ukufundile? Uma uhlangabezana nezinkinga ezivamile ezishiwo ngenhla, ungazama ukuzixazulula, mhlawumbe.
