Cov cuab yeej siv no yog ib txoj kev pheej yig rau DIYers rau tackle computer diagnostics, thiab lawv muaj peev xwm txawm yuav pab tau seasoned techs uas nrhiav tau lawv tus kheej kom deb ntawm lawv cov cuab yeej los ntawm cov cuab yeej sib tw. Txawm li cas los xij, muaj ob peb yam ELM327 Bluetooth teeb meem uas koj yuav tsum paub txog ua ntej koj tawm mus thiab yuav ib qho.
Qhov teeb meem pervasive feem ntau nrog ELM327 Bluetooth li yog tias qee tus nqi pheej yig tshaj nrog cov ELM327 microcontroller clones tsis tso cai. Cov chips ntawm cov kab no feem ntau pom muaj tus cwj pwm coj txawv txawv, tab sis txawm tias kev kho vajtse yeej tsis ua haujlwm nrog tej yam khoom siv. Yog tias koj xav siv ib qho cuab yeej iOS no los ua ib lub tshuab luam theej duab, nws yog ib qho tseem ceeb uas yuav tau them sai sai rau cov teeb meem no.
ELM327 Bluetooth Compatible Hardware
Luam theej duab cov cuab yeej uas muaj ELM327 microcontroller thiab Bluetooth chip muaj peev xwm ntawm kev sib txuam nrog ntau yam cuab yeej, tab sis kuj muaj qee cov kev txwv tseem ceeb. Qhov tseem ceeb tshaj plaws uas koj tuaj yeem siv lub ELM327 Bluetooth luam theej duab nrog:
- smartphones
- ntsiav tshuaj
- laptops
Txoj kev yooj yim tshaj plaws los mus ua kom zoo dua ELM327 Bluetooth connectivity yog khub lub scanner nrog ib lub xov tooj, tab sis tsis yog txhua lub xov tooj ua si zoo nrog lub tshuab. Qhov tshwj xeeb tshaj yog muaj xws li Apple iOS cov khoom zoo li lub iPhone, iPod kov, thiab iPad.
iOS pab kiag li lawm tsis ua hauj lwm nrog ELM327 scanners vim txoj kev uas tuam haujlwm ua haujlwm ntawm lub tuam txhab Bluetooth. Feem ntau cov ELM327 Bluetooth twj zoo li yuav tsis ua haujlwm nrog cov khoom kua, uas txhais tau hais tias cov neeg siv kua Apple zoo nrog USB thiab WI-ELM327 scanners. Cov khoom siv Jailbroken yog ib qhov txawv txav, tab sis muaj ntau tus neeg muaj kev phiv thiab muaj kev cuam tshuam nrog jailbreaking.
Hauv qee zaum, lwm cov smartphones kuj muaj teeb meem txog kev sib txuas nrog qee tus ELM327 Bluetooth scanners. Qhov no feem ntau yog vim muaj teeb meem nrog cov tsis tau tso cai, cloned microcontrollers uas tsis muaj txog hnub code.
Sib koom ELM327 Bluetooth Devices
Ib qho ntawm qhov teeb meem tau teev tseg saum toj no, pairing ELM327 Bluetooth devices nrog smartphones, ntsiav tshuaj, thiab PCs feem ntau yog ib txoj kev yooj yim. Cov kauj ruam tshaj plaws yog:
- Tuav tus ELM327 Bluetooth ntaus ntawv mus rau hauv qhov chaw nres nkoj OBD-II
- Teem lub smartphone, ntsiav tshuaj, los yog lub laptop rau "luam theej duab" rau kev sib txuas
- Xaiv qhov ELM327 luam theej duab
- Kev tawm tswv yim rau txoj cai pairing
Feem ntau, cov ntaub ntawv ua ke nrog ib tus ELM327 Bluetooth scanner yuav suav nrog txoj cai pairing thiab lwm yam kev qhia tshwj xeeb uas txawv ntawm qhov qauv qhia ntawv. Yog tias tsis muaj cov ntaub ntawv sau tseg, qee qhov kev cai muaj xws li:
- 0000
- 1234
- 6789
- 9999
Yog tias cov leb no tsis ua hauj lwm, tej zaum siv cov zauv ntawm plaub zauv.
Yuav Ua Li Cas Yog Pairing Fails
Yog tias koj lub ELM327 Bluetooth luam roj ntaus tsis ua haujlwm nrog koj lub smartphone, nws muaj ntau yam ua rau koj. Thawj kauj ruam uas koj yuav tsum tau ua yog sim sim nkawm cov cim. Tom qab ntawd, koj tuaj yeem sim ua tus ntaus cim nrog ib lub twj txawv. Qee faulty cloned ELM327 microcontrollers muaj teeb meem txuas rau tej yam khoom siv, thiab koj yuav pom tau tias koj lub luam txaj zoo nrog lub laptop thaum nws tsis kam txuas rau koj lub xov tooj.
Ib qho ntxiv uas yuav ua rau muaj kev sib tw ua tsis tau zoo yog qhov tsawg ntawm lub sij hawm uas koj qhov kev soj ntsuam tseem tshuav nrhiav tau. Feem ntau ntawm ELM327 Bluetooth scanners ua tau nrhiav tau sai sai thaum koj ntsaws lawv, tab sis lawv tsis pom tias nrhiav tau tom qab lub sijhawm ntau. Yog tias koj nco ntsoov ua haujlwm ob lub lag luam li ntawm ib feeb ntawm kev ntsaws lub cuab yeej rau lub OBD-II jack, yuav tsum tsis txhob muaj qhov teeb meem.
Yog tias koj lub cuab yeej theej duab tseem yuav tsis khub, ces tej zaum koj muaj qhov faulty chav tsev. Qhov no yog qhov tseem ceeb vim tias nws yog ib lub tswv yim zoo kom nyob deb ntawm pheej yig, scanners scanners thiab mus yuav koj lub luam tawm ntawm lub khw muag khoom uas yuav sawv tom qab cov khoom puas.
ELM327 Bluetooth Kev Xaiv
Lub tswv yim tseem ceeb mus rau ELM327 Bluetooth scanners yog li siv Wi-nkaus thiab USB txuas. WI-Fi ELM327 scanners yog feem ntau kim tshaj li cov uas siv Bluetooth, tab sis lawv tuaj yeem siv nrog kua cov khoom. Feem ntau USB ELM327 scanners tsis tsim los siv nrog cov khoom siv kua, tiam sis muaj qee qhov kev tso cai ntawm Apple uas tau siv nrog cov khoom nruab nrab.
