Ntau tus neeg xav tias kev sib txuas Bluetooth tsuas yog muaj kev sib txuas ib-rau-ib, tab sis kev sib txuas ib-rau-ib hauv ntau qhov kev thov tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, cov ntawv thov no xav tau ntau yam kev sib txuas Bluetooth. Ua raws li Feasycom ntau qhov kev sib txuas daws teeb meem.
Master/Slave ntau yam kev sib txuas
Tus tswv ua ke nrog cov qhev ib leeg. Txhua qhov kev sib txuas yuav tsim ib lub channel. Tus tswv tuaj yeem xa cov ntaub ntawv mus rau txhua lub channel lossis tau txais cov ntaub ntawv los ntawm txhua tus channel. Ntau qhov kev sib txuas tsis tuaj yeem xa cov ntaub ntawv tib lub sijhawm. Hauv lwm lo lus, kev sib txuas lus ntawm lawv tsis yog kev sib kis ntawm kev sib kis, thiab nws yuav tsum tau sib txuas lus nrog cov qhev sib txawv ntawm lub sijhawm sib txawv los ntawm kev xa cov lus qhia. Tus tswv- qhev ntau qhov kev sib txuas yog tsim rau kev tsim kho ntawm me me Piconet thiab Scatternet.
Bluetooth Mesh
Bluetooth Mesh muab ntau-rau-ntau qhov sib kis ntawm cov khoom siv, thiab muaj peev xwm tsim kom muaj kev pabcuam loj hauv lub network. Nws siv tshuab kev tswj dej nyab hauv network. Cov ntaub ntawv xa los ntawm ib lub node yuav raug xa mus los ntawm tag nrho cov nodes uas txhawb nqa relay, tab sis Nws yuav tsis raug xa mus tas li, thiab cov node uas tau xa cov ntaub ntawv yuav tsis xa mus ntxiv lawm. Nyob rau tib lub sijhawm, Bluetooth Mesh muaj qee cov txheej txheem tshwj xeeb, xws li kev tswj hwm lub neej ntawm pob ntawv (Time To Live), uas tseem tuaj yeem tiv thaiv kev xa tawm tsis txwv ntawm cov ntaub ntawv. Bluetooth Mesh yog qhov tsim nyog rau IoT cov kev daws teeb meem uas xav tau ntau txhiab lub cuab yeej xa mus rau hauv ib puag ncig txhim khu kev qha thiab nyab xeeb, xws li lub tsev automation thiab wireless sensor networks.
