UIFlow Qala ngokukhawuleza

Isixhobo esivuthayo

Phawula: Emva kofakelo lwabasebenzisi beMacOS, nceda ufake isicelo kwisiqulathi seefayili zeSicelo, njengoko kubonisiwe kumzobo ongezantsi.

Ukutshisa i-Firmware

1. Cofa kabini ukuvula isixhobo sokutshisa iSitshisi, khetha uhlobo lwesixhobo esihambelanayo kwimenyu yasekhohlo, khetha uhlobo lwe-firmware oyifunayo, kwaye ucofe iqhosha lokukhuphela ukukhuphela.
2. Emva koko uqhagamshele isixhobo se-M5 kwikhompyuter ngentambo yoHlobo lwe-C, khetha ichweba le-COM elihambelanayo, izinga le-baud linokusebenzisa uqwalaselo olungagqibekanga kwi-M5Burner, ukongeza, unokugcwalisa i-WIFI apho isixhobo siya kudityaniswa nayo ngexesha. ukutshisa i-firmware stage ulwazi. Emva koqwalaselo, cofa u-"Shisa" ukuqalisa ukutshisa.
3. Xa ilog evuthayo ikhuthaza ukutshisa ngempumelelo, kuthetha ukuba i-firmware itshisiwe.

Xa uqala ukutshisa okanye inkqubo ye-firmware iqhuba ngendlela engafanelekanga, unokucofa u-"Erase" ukucima imemori yeflash. Kuhlaziyo olulandelayo lwe-firmware, akukho mfuneko yokucima kwakhona, kungenjalo ulwazi olugciniweyo lwe-Wi-Fi luya kucinywa kwaye i-API Key iya kuhlaziywa.

Misela i-WIFI

I-UIFlow ibonelela zombini ngaphandle kwe-intanethi kunye web uguqulelo lomdwelisi. Xa usebenzisa i web version, kufuneka siqwalasele uqhagamshelo WiFi kwisixhobo. Oku kulandelayo kuchaza iindlela ezimbini zokuqwalasela uqhagamshelo lweWiFi kwisixhobo (Burn uqwalaselo kunye noqwalaselo lwe-AP hotspot).

Tshisa uqwalaselo lweWiFi (iyacetyiswa)

I-UIFlow-1.5.4 kunye neenguqulelo ezingentla zingabhala ulwazi lwe-WiFi ngqo nge-M5Burner.

Uqwalaselo lwe-APhotspot WiFi

1. Cinezela kwaye ubambe iqhosha lamandla ekhohlo ukuze uvule umatshini. Ukuba i-WiFi ayilungiselelwanga, inkqubo iya kungena ngokuzenzekelayo kwimowudi yoqwalaselo yenethiwekhi xa ivulwa okokuqala. Masithi ufuna ukungena kwakhona indlela yoqwalaselo lomsebenzi wothungelwano emva kokwenza ezinye iinkqubo, ungabhekisa kumsebenzi ongezantsi. Emva kokuba i-UIFlow Logo ibonakala ekuqaleni, nqakraza ngokukhawuleza iqhosha laseKhaya (iqhosha le-M5 embindini) ukufaka iphepha loqwalaselo. Cinezela iqhosha kwicala lasekunene le fuselage ukutshintshela ukhetho kuSeto, kwaye ucinezele iqhosha laseKhaya ukuqinisekisa. Cinezela iqhosha lasekunene ukutshintshela ukhetho kwi-WiFi Setting, cofa iqhosha laseKhaya ukuze uqinisekise, kwaye uqale uqwalaselo.
2. Emva kokudibanisa ngempumelelo kwi-hotspot ngefowuni yakho ephathwayo, vula isikhangeli sefowuni ephathwayo ukuskena ikhowudi ye-QR kwiscreen okanye ukufikelela ngokuthe ngqo ku-192.168.4.1, ngenisa iphepha ukuzalisa iinkcukacha zakho ze-WIFI, kwaye ucofe kuLungiselelo ukurekhoda ulwazi lwakho lwe-WiFi. . Isixhobo siya kuqalisa ngokuzenzekelayo emva kokuqwalasela ngempumelelo kunye nokufaka imo yenkqubo.

Phawula: Iimpawu ezikhethekileyo ezifana "nendawo" azivumelekanga kwiinkcukacha ze-WiFi emiselweyo.

Imowudi yeNkqubo yeNethiwekhi kunye ne-API KEY

Ngenisa imowudi yenkqubo yenethiwekhi

Imowudi yenkqubo yenethiwekhi yimowudi yokudock phakathi kwesixhobo se-M5 kunye ne-UIFlow web iqonga lokucwangcisa. Isikrini siza kubonisa imeko yangoku yoqhagamshelo lwenethiwekhi yesixhobo. Xa isalathisi siluhlaza, oko kuthetha ukuba ungafumana inkqubo yokutyhala nangaliphi na ixesha. Ngaphantsi kwemeko engagqibekanga, emva koqwalaselo lokuqala oluphumeleleyo lwenethiwekhi yeWiFi, isixhobo siya kuqalisa ngokuzenzekelayo kwaye singenise imowudi yenkqubo yenethiwekhi. Ukuba awuyazi indlela yokungenisa kwakhona imo yenkqubo emva kokwenza ezinye izicelo, ungabhekisa kule misebenzi ilandelayo.
