Bluetooth tuaj yeem xa cov ntaub ntawv.
Bluetooth Technology yog ib qho qhib kev tshwj xeeb rau cov ntaub ntawv wireless thiab kev sib txuas lus.Nws yog raws li tsawg - raug nqi luv -} deb ntawm wireless wireless sib txuasthiab teeb tsa kev sib txuas tshwj xeeb rau kev sib txuas lus ib puag ncig ntawm cov khoom siv tsau thiab mobile.
Cov hauv qab no yog cov lus qhia cuam tshuam rau cov ntaub ntawv sib kis ntawm Bluetooth:
Ua Haujlwm Cov Ntsiab Cai
- Zaus thiab zaus dhia:
Bluetooth kev ua haujlwm nyob rau hauv lub 2.4GHz Ism Band thiab ua haujlwm nrawm nrawm dhia dhia thev naus laus zis, muaj peev xwm hloov ntau zaus hauv ib thib ob. Los ntawm sai sai hloov ntawm ntau cov channels, nws txo cov co - zaus cuam tshuam thiab ua kom muaj kev ruaj ntseg ntawm cov ntaub ntawv kis. Lub Bluetooth classic muaj 79 raws, thaum tsawg - fais fab bluetooth muaj 40 channel.
- Cov ntaub ntawv pob ntawv qauv:
Cov pob ntawv Bluetooth muaj qhov siab tshaj plaws ntawm 357 bytes rau ib thav duab, thaum tsawg} Lub hwj chim Bluetooth muaj qhov siab tshaj plaws ntawm 261 bytes. Lub Bluetooth Bluetooth ua ntej muaj 9 -}} {{{{{{{} bytes, thiab thaum kawg ib qho 2-byte crc kos. Low-hwj huam Bluetooth pib nrog tus lej 1-byte ua ntej chaw nyob, tom qab ntawd ib qho 2-253 byte cov ntaub ntawv me ntsis, thiab thaum kawg ib qho 3-byte CRC daim tshev.
- Hom txuas:
Bluetooth txhais ob hom sib txuas, yog kev sib txuas tau - Kev sib txuas lus sib txuas lus (ACL). Qhov kev sib txuas Sco yog qhov kev sib txuas ib sab, feem ntau yog siv rau kev xa tawm tiag tiag {2} Lub suab nrov, thiab tseem siv tau los rov qab ib feem ntawm cov ntaub ntawv. Acl Links txhawb nqa ob qho tib si kev sib txuas thiab kev sib txuas asymmetric thiab tuaj yeem xa lub suab xov tooj, thiab lwm yam.
Cov Ntaub Ntawv Sib Kis
- Cov ntaub ntawv hloov ntawm cov khoom siv:
Thaum tsis muaj ntawm lub network, cov ntsiav tshuaj txawb, cov ntsiav tshuaj, khoos phis tawj thiab lwm cov khoom siv tuaj yeem sib txuas ntawm cov ntaub ntawv xws li cov duab, videos thiab cov ntaub ntawv. Piv txwv li, yog tias ob lub xov tooj ntawm tes muaj Bluetooth muab rau thiab tau xaiv ib daim duab, nyem Qhia tawm, Xaiv Bluetooth, thiab tom qab ntawd xaiv cov khoom siv ua khub. Cov ntaub ntawv hloov tsheb yuav pib.
- Sib koom tes:
Tom qab tig ntawm cov ntaub ntawv ntawm koj lub xov tooj ntawm tes, qhib lub Bluetooth ntawm ob lub xov tooj thiab khub lawv. Nyob rau hauv cov chaw ntawm lub xov tooj nrog cov ntaub ntawv, nrhiav "Hotspots" thiab tig rau "Share network ntawm Bluetooth". Lub xov tooj tsis muaj cov ntaub ntawv tuaj yeem txuas rau ib qho nrog cov ntaub ntawv ntawm Bluetooth kom hla kev hauv internet.
- Txuas cov ntse ntse li:
Bluetooth tuaj yeem txuas nrog Bluetooth lub mloog pob ntseg, cov neeg hais lus Bluetooth, ntse saib thiab lwm cov khoom siv kom ua tiav cov ntaub ntawv synchronous kis thiab sau cia. Piv txwv li, cov ntaub ntawv tawm dag zog thiab saib xyuas kev noj qab haus huv tuaj yeem raug xa mus rau lub xov tooj ntawm Bluetooth ntawm Bluetooth, ua rau nws yooj yim pom thiab txheeb xyuas ib tus kheej.
