Vim li cas tsis tuaj yeem Classic Bluetooth Module Tau Txais Kev Siv Hluav Taws Xob?
Qhov tshwm sim ntawm low-power bluetooth module tau txhim kho qhov tsis txaus ntawm classic bluetooth modules thiab tau dhau los ua tus qauv teeb tsa rau high-end smartphones. BLE module + ntse tsev, ua rau peb lub neej smarter.
Vim li cas ho tsis classic Bluetooth module ua kom tsis muaj zog noj?
Cia peb saib cov yam ntxwv ntawm Bluetooth qis zog module nrog Bluetooth module chaw tsim tshuaj paus Joinet:
1: Kev siv hluav taws xob tsawg tshaj plaws
Txhawm rau txo qis kev siv hluav taws xob, Bluetooth cov cuab yeej siv hluav taws xob tsawg siv feem ntau ntawm lawv lub sijhawm hauv hom pw tsaug zog. Thaum muaj kev ua ub no, lub cuab yeej cia li sawv thiab xa ntawv mus rau lub rooj vag, smartphone lossis PC. Qhov siab tshaj plaws / siab zog siv tsis tshaj 15mA. Kev siv hluav taws xob thaum siv yog txo rau ib feem kaum ntawm cov khoom siv Bluetooth tsoos. Hauv daim ntawv thov, lub pob roj teeb tuaj yeem ua haujlwm ruaj khov rau ntau xyoo.
2: Kev ruaj ntseg, kev ruaj ntseg thiab kev ntseeg siab
Bluetooth Low Energy thev naus laus zis siv tib yam Adaptive Frequency Hopping (AFH) thev naus laus zis raws li cov cuab yeej siv Bluetooth, yog li ua kom ntseeg tau tias Bluetooth Low Energy modules tuaj yeem tswj kev sib kis tau ruaj khov hauv "tsis nrov" RF ib puag ncig hauv thaj chaw, kev lag luam thiab kev siv kho mob. Txhawm rau txo tus nqi thiab kev siv hluav taws xob tsawg ntawm kev siv AFH, Bluetooth Low Energy thev naus laus zis tau txo cov xov tooj ntawm 79 1 MHz dav raws ntawm cov qauv Bluetooth tshuab mus rau 40 2 MHz wide channels.
3: Wireless Coexistence
Bluetooth technology siv 2.4GHz ISM zaus band uas tsis tas yuav muaj daim ntawv tso cai. Nrog ntau cov thev naus laus zis sib koom qhov chaw huab cua no, kev ua haujlwm wireless raug kev txom nyem los ntawm kev kho qhov yuam kev thiab rov xa rov qab los ntawm kev cuam tshuam (xws li nce latency, txo cov kev xa tawm, thiab lwm yam). Hauv kev thov kev thov, kev cuam tshuam tuaj yeem raug txo los ntawm kev npaj ntau zaus thiab tsim tshwj xeeb kav hlau txais xov. Vim tias ob qho tib si Bluetooth module ib txwm siv thiab Bluetooth qis zog module siv AFH, lub tshuab uas tuaj yeem txo qhov cuam tshuam ntawm lwm yam xov tooj cua, Bluetooth kis tau zoo heev thiab kev ntseeg tau.
4: Kev sib txuas ntau yam
Qhov kev hloov pauv ntawm Bluetooth tsis tshua muaj zog thev naus laus zis yog qhov txawv me ntsis ntawm cov cuab yeej Bluetooth ib txwm siv. Qhov kev sib txawv no ua rau muaj kev sib txuas ntau txog 300 meters ntawm lub wireless chipset ntawm 10 dBm (Bluetooth Tsawg Zog siab tshaj plaws).
5: Kev yooj yim ntawm kev siv thiab kev koom ua ke
Lub Bluetooth qis zog piconet feem ntau yog raws li tus tswv cuab yeej txuas nrog ntau yam qhev. Hauv piconet, txhua yam khoom siv yog tus tswv lossis qhev, tab sis tsis tuaj yeem yog ob tus tswv thiab qhev tib lub sijhawm. Tus tswv cuab yeej tswj hwm kev sib txuas lus ntau zaus ntawm cov cuab yeej qhev, thiab cov cuab yeej qhev tsuas tuaj yeem sib txuas lus raws li qhov xav tau ntawm tus tswv cuab yeej. Piv nrog rau cov cuab yeej Bluetooth ib txwm siv, ib txoj haujlwm tshiab ntxiv los ntawm Bluetooth tsis tshua muaj zog thev naus laus zis yog "tshaj tawm" muaj nuj nqi. Nrog rau qhov no feature, ib tug qhev ntaus ntawv yuav qhia tau hais tias nws yuav tsum tau xa cov ntaub ntawv mus rau tus tswv ntaus ntawv.
Txij li thaum lub cev txheej txheem kev hloov pauv thiab kev txiav txim siab ntawm classic Bluetooth thiab qis zog Bluetooth yog qhov sib txawv, cov khoom siv Bluetooth qis thiab cov khoom siv Bluetooth classic tsis tuaj yeem sib txuas lus. Yog hais tias tus tswv ntaus ntawv yog ib tug low-power Bluetooth ntaus ntawv, tus qhev ntaus ntawv kuj yuav tsum tau ib tug low-power Bluetooth ntaus ntawv; Ib yam li ntawd, ib qho classic Bluetooth qhev ntaus ntawv tuaj yeem sib txuas lus nrog classic Bluetooth master ntaus ntawv.
Joinet, raws li kev tshawb fawb thiab kev loj hlob thiab chaw tsim tshuaj paus ntawm low-power Bluetooth modules, ntxiv rau cov tsis muaj zog Bluetooth modules, peb kuj muaj cov kev daws teeb meem, xws li: ntse txhuam hniav, networked dej purifiers, thiab lwm yam. Txais tos kom sab laj!
