HC - 05 Tswv Yim Pab Slave Wireless Serial Bluetooth Module RF Transceiver tsis muaj Baseplate rau arduino uno r3
Yog tias koj xav nkag mus rau hom AT
Tsuas tuav khawm
Mus txog thaum ua tiav
Cov ntaub ntawv hauv qab no tsis muab, rau ntau yam, tsis txhob "kawm tiav kev xav tau" thiab nug, tsis txaus siab tsis txhob yuav:
1, daim ntawv qhia thiab CD-ROM
2, cov ntaub ntawv tsim qauv, nrog rau tiam sis tsis tas rau cov ntaub ntawv SCH, PCB cov ntaub ntawv
3, ntau microcontroller kawg ntawm qhov kev xeem ntawv
4, lwm yam khoom siv txawj ntse (xws li PDA, PSP, xov tooj txawb thiab lwm yam ntau hom) cov txheej txheem ntawm cov txheej txheem
5, tau piav qhia saum toj no ntxiv rau lwm cov ntaub ntawv kuj yuav muab tau rau sab nraud
CEEB TOOM! ! ! Tsis txhob muab lub hwj chim tso rau ntawm lub teeb liab, nws yuav hlawv ncaj qha!
Cov nram qab no tsis yog cov khoom muaj teeb meem, cov xov tooj uas tsis tau raug tshem tawm hauv lub warranty yuav tsis rov qab:
1, txij li kev kaw qhov kev ntsuam xyuas tau zoo, kev siv TXD lossis RXD ua rau luv luv Circuit Court nrog rau hauv av
2, tsis muaj fais fab mov tiv thaiv dua rov qab ua kev puas tsuaj rau lub hwj chim khoom
1.1 Lub tswv yim (tseem ceeb heev):
TXAWJ: Xa sab, feem ntau hais raws li lawv tus kheej sender, kev sib txuas lus li RXD yuav tsum txuas nrog rau lwm lub tshuab.
RXD: qhov kawg uas tau txais, feem ntau yog nws tus kheej rau ntawm qhov kawg, kev sib txuas lus li niaj zaus TXD yuav tsum txuas nrog lwm lub tshuab.
Thaum twg qhov kev sib txuas lus nws tus kheej TXD RXD ib txwm txuas nrog ntaus ntawv!
Txij li thaum rov qab pib dua: RXD kev sib txuas lus nkag mus rau lwm cov cuab yeej TXD, yog li yog koj xav tau cov ntaub ntawv xa los ntawm nws tus kheej raws li lub npe pom zoo, yuav tau txais cov ntaub ntawv uas lawv xa tawm, uas yog ncaj qha mus rau nws tus kheej TXD RXD, siv mus tshaj tawm thiab tau txais kev xeem ntawv Nws yog qhov qub, yog txoj kev sai thiab yooj yim tshaj plaws los ntsuam xyuas thaum muaj qhov teeb meem tshwm sim thawj zaug ua qhov kev xeem no los txiav txim seb puas muaj cov khoom tsis ua haujlwm. Kuj hu ua qhov kev xeem loopback.
1.2 Qib Logic:
TTL qib: feem ntau piv tau cov ntaub ntawv binary, + 5V sib npaug rau cov zajlus kom "predetermined", 0V yog sib npaug ntawm logic "0", qhov system hu ua TTL teeb liab yog qhov zoo logic
RS232 qib: siv-12V rau - 3V, yog sib npaug ntawm cov "0", 3V mus rau + 12V logic level, sib npaug ntawm cov zajlus kom "1" yog ib qho tsis zoo logic
1.3 Khoom Nta:
1, tus ntxhais module HC-05 ntawm qhov module, ua rau kom muaj kev sib txuas nrog VCC, GND, TXD, RXD, KEY PIN, Bluetooth txuas raws li txoj cai pinout (NRHIAV), tsis txuas nrog cov zis tsawg, tom qab txuas high output
2, coj qhia txog txoj cai ntawm Bluetooth txuas, Bluetooth connectivity txhais tau tias tsis muaj flash, qeeb flash uas nkag mus rau AT hom, ob npaug rau flash qhia Bluetooth txuas nrog thiab qhib rau ntawm qhov chaw nres nkoj
3, hauv qab teev ntsuas diodes nrog 3.3V LDO, input voltage 3.6 ~ 6V, thaum lub unpaired tam sim no txog 30mA, paired txog 10mA, qhov input voltage txwv tsis pub tshaj 7V!
4, lub theem tshooj 3.3V, tuaj yeem ncaj qha mus rau ntau yam SCM (51, AVR, PIC, ARM, MSP430, thiab lwm yam.), 5V microcontroller kuj tuaj yeem ncaj qha mus, tsis muaj MAX232 MAX232!
5, qhib rau txoj kev zoo ntawm 10 meters (fais fab kev ntsuas ntawm CLASS 2), ntau tshaj 10 meters tau, tab sis tsis txhob ua qhov no los xyuas kom zoo ntawm qhov kev txuas txuas
6, tom qab khub thaum full-duplex serial interface, tsis paub xyov kev cai lij choj ntawm Bluetooth 8 cov khoom khaws tseg, 1 nres me ntsis, parity sib txuas lus hom yuav tau teev, uas yog hom siv hom kev tshaj plaws tsis txhawb lwm hom ntawv.
7, tuaj yeem rub 34 ko taw rau hauv AT hais kom ua hom teeb thiab lus nug
8, compact (3.57cm * 1.52cm), lub hoobkas nti khoom tsim kom muaj kev tso kawm zoo. Thiab npaj pob tshab shrink tube, plua tshauv thiab zoo nkauj, thiab muaj ib qho kev tiv thaiv tsis zoo ntawm lub cev.
9, tuaj yeem hloov ntawm AT commands li tus tswv lossis tus qhev hom, koj tuaj yeem txuas mus rau daim ntawv teev lus qhia hauv AT commands
10, kev txhawb los ntawm cov txheej txheem baud rate 4800bps ~ 1382400bps
1.4 Siv:
Tom qab sib khawm cia li tas li ntawm qhov chaw nres nkoj yuav tsum siv tau tib yam nkaus, tsuav yog tias "baud fixed, 8 bits data, no parity, Koj tsis tas yuav hloov qhov kev pab cuam. Xws li cov ntaub ntawv tshaaj, lub ntse lub tsheb, cov tshuab luam ntawv, sab nraum cov teeb Screen ntxig Screen.
Paired nrog lub computer: rau ntawm cov computers ntawm Bluetooth kev sib txuas lus nrog lub ntaus ntawv, siv tib qhov chaw nres nkoj
Paired nrog rau cov xov tooj siv: rau ntawm koj lub xov tooj ntawm Bluetooth ntawv txuas lus nrog lub ntaus ntawv, siv tib qhov chaw nres nkoj
Paired nrog ib tug tswv tsev Bluetooth: rau ob yam khoom ncaj nraim ntawm Bluetooth lus txuas, xws li ntawm microcontroller thiab microcontroller serial cable nrog microchips, thiab lwm yam., Siv tib qho chaw nres nkoj
Siv tau yooj yim:
Baud rate conversion, vim hais tias tus neeg txais kev pab thiab tus neeg xaib xaiv tau xaiv lawv tus kheej baud tus nqi, thaum ib tus nqi tsawg tsawg ntawm cov ntaub ntawv siv tau los ua tus nqi baud rate conversion.
2.1 Yuav ua li cas txuas rau lub computer Bluetooth module (ntawm hom)
Cov nram qab no thiaj li nrog lub computer paired nrog Bluetooth raws li ib qho piv txwv:
Ua ntej dhau ntawm Bluetooth module fais fab, lub sij hawm no tau ntsais muag, qhib "Kuv qhov chaw nyob hauv bluetooth", nias "Tshawb nrhiav kev pab nyob rau hauv ntau"
Lub system yuav tshawb rau cov cuab yeej Bluetooth, lub neej ntawd ntaus lub npe "linvor" (li hloov lub npe tau hloov lub npe, xws li "jiayuanelectron"), ob-nias los yog txoj nyem thiab xaiv "Ntxiv ib qho Bluetooth device"
Sau ib passcode (lub neej ntawd yog "1234"),
Nyem "Tom ntej", yog hais tias tus password muaj tseeb, lub computer thiab qhov kev sib tw dhau los ntawm qhov kev sib txuas yog tsim muaj, yog tias yav tas los tsis tau muaj kev sib xyaw nrog Bluetooth, cov system yuav tau nruab tus tsav tsheb thiab tsim kom muaj qhov chaw nres tsheb virtual
Nyem Configuration, xaiv qhov chaw nres tsheb kom tsim nyog,
Kuv nyob ntawm no tsuas yog xaiv com5, qhov chaw nres nkoj ces txuas nrog lub computer tom qab kawg ntawm kev khiav lag luam, xws li kuv muaj ntawm no yog com5, qhib qhov chaw nres nkoj thaum Bluetooth module ntawm LED yuav nyem rau hauv ob chav flash, ces cia li coj Bluetooth module raws li lub koos pis tawj ntawm lub computer kom siv baud feem siv tib yam, tshwj tias nws yog wireless.
Cim npe nrov: hc-05 wireless bluetooth tsis muaj tus tswv lag luam hauv tuam txhab Suav teb, manufacturers, luv nqi, yuav luv nqi, pricelist, nqe, hauv Suav teb
