Bluetooth lub suab tswj chaw taws teeb tau maj mam hloov cov tsoos infrared chaw taws teeb tswj, thiab tau maj mam dhau los ua cov khoom siv niaj hnub no hauv tsev teeb tsa lub thawv.Los ntawm lub npe ntawm "Bluetooth Voice Remote Control", nws tsuas yog muaj ob yam: Bluetooth thiab lub suab.Bluetooth muab cov channel thiab cov txheej txheem sib kis rau lub suab cov ntaub ntawv xa mus, thiab lub suab paub txog tus nqi ntawm Bluetooth.Ntxiv rau lub suab, cov nyees khawm ntawm Bluetooth lub suab tswj chaw taws teeb kuj tseem xa mus rau lub thawv teeb tsa los ntawm Bluetooth.Kab lus no qhia txog qee lub ntsiab lus ntawm Bluetooth lub suab tswj chaw taws teeb.

1. Qhov chaw ntawm lub pob "Suab" thiab lub microphone qhov ntawm Bluetooth lub suab tswj chaw taws teeb

Ib qhov sib txawv ntawm Bluetooth lub suab tswj chaw taws teeb thiab cov tsoos infrared chaw taws teeb tswj nyob rau hauv cov nqe lus ntawm cov nyees khawm yog tias yav tas los muaj ib qho ntxiv "lub suab" khawm thiab lub microphone qhov.Tus neeg siv tsuas yog yuav tsum tuav lub pob "Suab" thiab hais lus rau hauv lub microphone.Nyob rau tib lub sijhawm, lub microphone yuav sau tus neeg siv lub suab thiab xa mus rau lub npov saum toj kawg nkaus rau kev tshuaj xyuas tom qab kuaj, quantization, thiab encoding.

Txhawm rau kom tau txais kev paub suab zoo nyob ze, qhov teeb tsa ntawm "Suab" khawm thiab txoj haujlwm ntawm lub microphone ntawm cov chaw taws teeb tswj yog tshwj xeeb.Kuv tau pom qee lub suab tswj chaw taws teeb rau TVs thiab OTT teeb tsa lub thawv, thiab lawv cov "lub suab" cov yawm sij kuj tau muab tso rau hauv ntau txoj haujlwm, qee qhov tau muab tso rau hauv nruab nrab ntawm cov chaw taws teeb tswj, qee qhov tau muab tso rau hauv qhov chaw saum toj kawg nkaus. , thiab qee qhov tau muab tso rau hauv qhov chaw sab saud sab xis, thiab txoj haujlwm ntawm lub microphone feem ntau muab tso rau hauv nruab nrab ntawm thaj chaw saum toj kawg nkaus.

2. BLE 4.0 ~ 5.3

Lub Bluetooth lub suab tswj chaw taws teeb muaj lub built-in Bluetooth nti, uas siv lub zog ntau dua li ib txwm infrared chaw taws teeb tswj.Txhawm rau kom lub neej ntev ntawm lub roj teeb, Bluetooth lub suab tswj chaw taws teeb feem ntau xaiv BLE 4.0 lossis siab dua tus qauv raws li tus qauv kev siv.

Lub npe tag nrho ntawm BLE yog "BlueTooth Tsawg Zog".Los ntawm lub npe, nws tuaj yeem pom tias kev siv hluav taws xob tsawg tau hais meej, yog li nws tsim nyog rau Bluetooth lub suab tswj chaw taws teeb.

Zoo li TCP/IP raws tu qauv, BLE 4.0 kuj qhia txog cov txheej txheem ntawm nws tus kheej raws tu qauv, xws li ATT.Hais txog qhov sib txawv ntawm BLE 4.0 thiab Bluetooth 4.0 los yog yav dhau los Bluetooth version, kuv nkag siab nws zoo li no: lub version ua ntej Bluetooth 4.0, xws li Bluetooth 1.0, belongs rau ib txwm Bluetooth, thiab tsis muaj kev tsim muaj feem xyuam rau kev siv hluav taws xob tsawg;los ntawm Bluetooth 4.0 Thaum xub thawj, BLE raws tu qauv tau ntxiv rau yav dhau los Bluetooth version, yog li Bluetooth 4.0 suav nrog ob qho tib si yav dhau los Bluetooth raws tu qauv thiab BLE raws tu qauv, uas txhais tau hais tias BLE yog ib feem ntawm Bluetooth 4.0.

Pairing kev twb kev txuas raws li txoj cai:

Tom qab cov chaw taws teeb tswj thiab lub thawv teeb tsa tau ua ke thiab txuas nrog, ob leeg tuaj yeem xa cov ntaub ntawv.Tus neeg siv tuaj yeem siv cov chaw taws teeb tswj cov yuam sij thiab lub suab yuam sij los tswj lub npov saum toj kawg nkaus.Lub sijhawm no, tus nqi tseem ceeb thiab cov ntaub ntawv suab raug xa mus rau lub thawv teeb tsa los ntawm Bluetooth.

Pw tsaug zog xeev thiab active xeev:

Txhawm rau kom lub neej ntev roj teeb, thaum lub chaw taws teeb tswj tsis siv rau lub sijhawm, cov chaw taws teeb tswj yuav cia li mus pw.Thaum lub sijhawm pw tsaug zog ntawm cov chaw taws teeb tswj, los ntawm nias ib lub pob, cov chaw taws teeb tswj tuaj yeem qhib tau, uas yog hais tias, cov chaw taws teeb tswj tuaj yeem tswj lub thawv teeb tsa saum toj kawg nkaus los ntawm Bluetooth channel nyob rau lub sijhawm no.

Bluetooth tseem ceeb tus nqi txhais

Txhua lub pob ntawm Bluetooth lub suab tswj chaw taws teeb sib raug rau tus nqi tseem ceeb ntawm Bluetooth.Muaj ib lub koom haum thoob ntiaj teb uas txhais cov txheej txheem ntawm cov yuam sij rau cov keyboards, thiab lub sij hawm yog keyboard HID keys.Koj tuaj yeem siv cov txheej txheem ntawm cov keyboard HID no ua cov yuam sij Bluetooth.

Cov saum toj no yog cov ntsiab lus ntawm cov ntsiab lus tseem ceeb thiab cov thev naus laus zis koom nrog hauv Bluetooth lub suab tswj chaw taws teeb.Kuv yuav qhia luv luv ntawm no.Zoo siab txais tos nug cov lus nug thiab sib tham ua ke.
