Hnub no, tej zaum, txhua tus neeg siv khoom siv hluav taws xob paub tias Bluetooth yog dab tsi. Tab sis tsis yog txhua tus paub tias hom kev sib pauv ntaub ntawv no tau hloov kho, thiab dhau sijhawm, nws cov kev hloov kho tshiab tshwm sim. Yuav ua li cas kom paub qhov version ntawm bluetooth ntawm lub xov tooj Android? Koj yuav pom cov lus teb rau lo lus nug no hauv kab lus no.
Bluetooth. Creation keeb kwm
Hnub no, yuav luag txhua yam khoom siv (xov tooj, ntsiav tshuaj, laptop) muaj lub teeb tsa hauv bluetooth. Bluetooth yog ib hom kev sib txuas wireless rau kev xa cov ntaub ntawv. Cov khoom siv tuaj yeem txuas nrog ntawm qhov deb txog li 10 meters ntawm ib leeg, thiab tus neeg xa khoom thiab tus neeg txais tuaj yeem nyob hauv cov chav sib txawv. Lub hauv paus ntsiab lus ua haujlwm ntawm bluetooth yog dab tsi? Cov thev naus laus zis no siv xov tooj cua los pauv cov ntaub ntawv.
Ua haujlwm ntawm kev tsim Bluetooth wireless kev sib txuas lus pib rov qab rau xyoo 1994, thiab plaub xyoos tom qab ntawd, thawj cov qauv - 1.0 thiab 1.0B - tau luam tawm los ntawm Bluetooth Tshwj Xeeb Pab Pawg. Thaum xub thawj, cov khoom siv nrog cov qauv no tsis zoo sib xws ntawm cov khoom siv.txawv manufacturers. Tab sis xyoo 2004, kev hloov kho ntawm Bluetooth 2.0 tau nthuav tawm, lub ntsiab lus tseem ceeb ntawm kev txhawb nqa rau EDR (Enhanced Data Rate) thev naus laus zis, uas tau nrawm nrawm cov ntaub ntawv pauv mus rau yuav luag 3 Mbps.
Bluetooth Tsawg Zog
Ib kauj ruam loj hauv kev txhim kho hom kev sib txuas lus no yog version 4.0, tso tawm los ntawm Bluetooth SIG hauv xyoo 2010. Pib nrog qhov kev qhia tshwj xeeb no, muaj kev txhawb nqa rau Tsawg Zog, lossis siv hluav taws xob tsawg. Qhov no tso cai rau cov cuab yeej siv hluav taws xob tsawg thaum lub sijhawm ua haujlwm, thiab yog li ua haujlwm ntev dua yam tsis tau them rov qab. Feem ntau, cov chips ntawm cov ntawv tshwj xeeb no tau ua rau ntau yam khoom siv niaj hnub no: watches, motion sensors, gamepads, wireless keyboards, Fit bracelets, thiab lwm yam. Cov khoom siv no tuaj yeem ua khub nrog lub xov tooj lossis ntsiav tshuaj los pauv cov ntaub ntawv.
Tab sis vim li cas nws tseem ceeb heev kom paub cov bluetooth version? Piv txwv li, Xiaomi Mi Band 2 bracelet txhawb Bluetooth 4.0. Tab sis koj lub xov tooj smartphone yuav muaj qhov tshwj xeeb bluetooth yav dhau los - qis dua 4.0, piv txwv li, 3.0, thiab yog li kev sib txuas ntawm cov khoom siv tsis tuaj yeem tsim, thiab tus neeg siv yuav ntsib kev poob siab zoo. Yog li, yuav ua li cas kom paub qhov version ntawm bluetooth ntawm "Android" ntaus ntawv? Peb muaj ntau txoj kev xaiv.
