Bluetooth tsawg lub zog (BLE) thiab classic Bluetooth yog ob daim ntawv loj ntawm bluetooth technology. Txawm hais tias ob qho tib si siv rau kev sib txuas lus wireless, lawv muaj qhov sib txawv hauv cov hom phiaj tsim, cov ntaub ntawv sib kis, thiab lwm yam hauv qab no yog lawv qhov sib txawv:
1. Cov hom phiaj tsim qauv
Core Daim Ntawv Thov:Tsim los rau qis - Hwj chim, muaj cov khoom siv uas tsim nyog (xws li dab teg, ntshav ntshav roj av), beacons, thiab lwm yam.
Kev noj fais fab:Tsis tshua muaj hluav taws xob tsis tshua muaj hluav taws xob nplua nuj (cov roj teeb khawm tuaj yeem ua haujlwm rau lub hlis lossis xyoo tas los).
Txoj Kev Txuas:Sai sai tsim kom luv - xyoo kev twb kev txuas thiab mus rau hauv hom pw tsaug zog tam sim ntawd tom qab kis tau.
Classic Bluetooth
Core Daim Ntawv Thov:Txhawb kev txuas ntxiv, siab {- bandewidth cov ntaub ntawv kis, cov neeg hais lus), cov ntaub ntawv hloov (FTP), peripherals (nas, cov keyboard), thiab lwm yam.
Kev noj fais fab:Cov hluav taws xob tau noj ntau dua (yuav tsum tau them nuj nqis lossis hluav taws xob muab khoom).
Txoj Kev Txuas:Tswj kev sib txuas ruaj khov, haum rau tiag -} Cov ntaub ntawv cov ntaub ntawv kis tau.
2. Hwj chim noj kev sib piv
| Cov yam ntxwv | Leeg | Classic Bluetooth |
|---|---|---|
| Ncov tam sim no | -15 ma (qis dua thaum tshaj tawm xov xwm | -30 ~ 100 ma (txuas ntxiv txuas) |
| Xuas Kev Tiv Thaiv Kev Tivum | Qib microophere (μA) | Milliampere -} theem (ma) |
| Roj teeb lub neej | Ob peb hlis mus rau ntau xyoo | Txij li ob peb teev mus rau ntau hnub |
3. Cov Ntaub Ntawv Kis Muaj Peev Xwm
| Cov yam ntxwv | Leeg | Classic Bluetooth |
|---|---|---|
| Cov ntaub ntawv tus nqi | 1-2 MBPS (Bluetooth 5.0+) | 1-3 Mbps (Bluetooth 3.0+) |
| Cov Pob Ntawv Pob Ntawv Loj | Me me (Haum rau cov lus qhia / Sensors) | Loj (haum rau cov ntaub ntawv audio / cov ntaub ntawv) |
| Tos | Qis dua (millisecond theem) | Tus siab (siab rau cov qauv) |
4. Raws li kev cai thiab kev sib raug zoo
- Txawv kev sib txawv sib sib koom
BLE CLE Siv Gatt (General Manocol raws tu qauv) thiab yog raws li cov kev pabcuam "Egenvalue" qauv (xws li lub plawv dhia, roj teeb tshwj xeeb).
Classic Bluetooth siv cov kev cai xws li SPP (Serial Portic Formocal) thiab A2DP (audio kis protocol).
- Kev sib haum
Cov cuab yeej siv nrog Bluetooth 4.0 thiab siab dua txhawb ob qho tib si classic (piv txwv li, tab sis qee lub mloog lus qub xwb,
5. Cov ntaub ntawv raug cai
| Leeg | Classic Bluetooth |
|---|---|
| Cov Khoom Noj Qab Haus Huv (Wristbands, Ntshav Siab Saib Xyuas) | Wireless Headphones thiab Cov Neeg Hais Lus |
| Nyob sab hauv tsev (beacon) | Cov ntaub ntawv hloov ntaub ntawv (xov tooj txawb - lub computer) |
| Ntse Tsev Sensors (Kub thiab Vaum) | {{0 {}} dawb hauv -} tsheb hu |
6. Yuav ua li cas xaiv?
- Siv ble yog tias:
Ultra - Tsawg zog siv hluav taws xob thiab sib kis tau (xws li sensors) yuav tsum muaj.
Cov cuab yeej yog qhov loj me me thiab muaj roj teeb tsawg muaj peev xwm (xws li cov khoom siv hnav tau).
- Siv Bluetooth yog:
High bandwidth lossis tiag - kev ua tau zoo (xws li audio thiab video).
Cov cuab yeej siv tau muaj zog (xws li cov khoom siv rechargeable).
Lub ntsiab
Hnyo thiab classic Bluetooth yog cov thev naus laus zis ntxiv:
- Hnyo =} fais fab txuag + cov ntaub ntawv me (lub zog tseem ceeb ntawm is taws nem ntawm tej yam).
- Classic Bluetooth=kev ua haujlwm siab + tiag- lub sijhawm (nyiam rau cov khoom siv audio / peripheral).
Dual - Hom Khoom Siv Nrog Bluetooth4.0+ tuaj yeem txuas nrog ob lub pob ntseg thiab lub dab teg).
