Bluetooth yog tus qauv thev naus laus zis rau cov ntaub ntawv luv luv wireless kis ntawm cov khoom siv uas muaj cov chips sib xws. Muaj ob lub thev naus laus zis loj hauv Bluetooth core specification-Bluetooth classic thiab Bluetooth Smart (Bluetooth Tsawg Zog). Ob lub thev naus laus zis suav nrog kev ua haujlwm xws li kev tshawb pom thiab kev sib txuas, tab sis lawv tsis tuaj yeem sib txuas lus nrog ib leeg. Yog li ntawd, muaj qhov sib txawv ntawm Bluetooth ib hom thiab Bluetooth dual-hom ntawm cov khoom siv kho vajtse. Lub Bluetooth hauv peb niaj hnub siv smartphones yog Bluetooth dual-hom, uas tuaj yeem txhawb Bluetooth Classic thiab Bluetooth Tsawg Zog.
Bluetooth Classic
Bluetooth Classic yog tsim los txuas ntxiv ob txoj kev hloov cov ntaub ntawv nrog cov ntawv thov siab (txog 2.1 Mbps); zoo heev, tab sis tsuas yog rau luv luv. Yog li, nws yog ib qho kev daws teeb meem zoo tshaj plaws nyob rau hauv cov ntaub ntawv ntawm streaming suab thiab video, los yog nas thiab lwm yam khoom siv uas xav tau kev txuas mus tas li, broadband.
Classic Bluetooth txhawb kev cai: SPP, A2DP, HFP, PBAP, AVRCP, HID.
Bluetooth Tsis Muaj Zog
Kev tshawb fawb SIG nyob rau kaum xyoo dhau los tau nrhiav kev txhim kho kev ua tau zoo ntawm Bluetooth hais txog kev siv hluav taws xob, tuaj txog rau xyoo 2010 tus qauv Bluetooth Tsawg Zog (BLE). Bluetooth Low Energy yog ib qho ultra-low zog version ntawm Bluetooth txhais tau tias rau qis zog sensors thiab accessories. Nws yog qhov zoo tagnrho rau cov ntawv thov uas tsis tas yuav txuas ntxiv tab sis nyob ntawm lub roj teeb lub neej ntev.
LUB SIJ HAWM NTAWM BLUETOOTH CLASSIC THIAB BLE
Bluetooth Classic yog qhov zoo tagnrho rau cov khoom lag luam uas xav tau kev sib txuas lus ntawm lub suab thiab cov ntaub ntawv xa mus, xws li:
- Lub taub hau wireless
- Hloov cov ntaub ntawv ntawm cov khoom siv
- Wireless keyboards thiab printers
- Hais lus wireless
Bluetooth Tsawg Zog (Bluetooth LE) yog qhov tsim nyog rau kev siv IoT xws li:
- Saib xyuas sensors
- BLE Beacons
- Sib thooj lag luam
Txhawm rau ua kom tiav, Bluetooth Classic tsis yog ib qho qub version ntawm BLE. Bluetooth Classic thiab Bluetooth Low Energy coexist thiab siv nyob rau hauv ntau daim ntawv thov. Nws tag nrho yog nyob ntawm txhua tus neeg xav tau kev sib txawv!
