Kev sib txuas lus wireless tau dhau los ua tus choj tsis pom hauv Is Taws Nem ntawm Yam Kev Sib Txuas, thiab Bluetooth, raws li lub ntsiab lus wireless sib txuas lus thev naus laus zis, ua lub luag haujlwm tseem ceeb hauv Internet of Things daim ntawv thov. peb tau txais kev nug los ntawm cov neeg siv khoom txog Bluetooth module qee zaum, tab sis thaum lub sijhawm kev sib txuas lus, kuv pom tias qee tus engineers tseem tsis meej txog lub tswv yim ntawm Bluetooth module ua tus tswv thiab qhev, tab sis peb muaj kev xav paub txog technology, peb yuav ua li cas. zam lub neej ntawm kev paub li cas txog qhov muag tsis pom?
Feem ntau peb hu BLE Center "Master mode", hu rau BLE peripheral "Slave".
BLE muaj lub luag haujlwm hauv qab no: Advertiser, Scanner, qhev, Master, thiab Initiator, qhov twg tus tswv hloov dua siab tshiab los ntawm tus pib thiab lub scanner ntawm qhov tod tes, tus qhev ntaus ntawv hloov dua siab tshiab los ntawm tus tshaj tawm xov xwm; Bluetooth module kev sib txuas lus yog hais txog kev sib txuas lus ntawm ob lub Bluetooth modules lossis Bluetooth li. Ob tog rau kev sib txuas lus cov ntaub ntawv yog tus tswv thiab tus qhev
Master ntaus hom: Nws ua haujlwm nyob rau hauv tus tswv ntaus ntawv hom thiab tuaj yeem txuas nrog tus qhev ntaus ntawv. Hauv hom no, koj tuaj yeem tshawb nrhiav cov khoom siv ib puag ncig thiab xaiv cov khoom siv qhev uas yuav tsum tau txuas rau kev sib txuas. Hauv txoj kev xav, ib lub cuab yeej Bluetooth tus tswv tuaj yeem sib txuas lus nrog 7 Bluetooth qhev li tib lub sijhawm. Ib qho khoom siv nrog Bluetooth kev sib txuas lus muaj nuj nqi tuaj yeem hloov ntawm ob lub luag haujlwm. Nws feem ntau ua haujlwm hauv hom qhev thiab tos rau lwm yam khoom siv los txuas. Thaum xav tau, nws hloov mus rau hom tswv thiab pib hu rau lwm yam khoom siv. Thaum lub cuab yeej Bluetooth pib hu rau hauv hom tseem ceeb, nws yuav tsum paub lwm tus neeg lub chaw nyob Bluetooth, txuas tus password, thiab lwm yam ntaub ntawv. Tom qab ua khub tiav lawm, hu tuaj yeem pib ncaj qha.
Xws li FSC-BT616 TI CC2640R2F BLE 5.0 Module:
Tus qhev ntaus hom: Bluetooth module ua haujlwm hauv hom qhev tsuas yog tuaj yeem tshawb xyuas los ntawm tus tswv tsev, thiab tsis tuaj yeem tshawb nrhiav. Tom qab tus qhev ntaus ntawv txuas nrog tus tswv tsev, nws tseem tuaj yeem xa thiab tau txais cov ntaub ntawv nrog tus tswv tsev.
