Arduino Cellular Shield tso cai rau koj hu xov tooj ntawm tes, thiab xa xov. Lub hlwb ntawm daim ntaub thaiv no yog SM5100B uas yog lub xov tooj ntawm tes muaj zog muaj peev xwm ua tau ntau txoj haujlwm ntawm feem ntau ntawm cov xov tooj ntawm tes. Cov ntaub thaiv npog no yuav tsum siv daim npav SIM txuas rau lub xov tooj ntawm tes. Cov ntawv qhia uas ua hauv qab no yog cov pob txha liab qab qhia rau pib ua daim ntaub thaiv, thiab ob qho tib si xa thiab txais ntawv xov xwm, thiab hu xov tooj. Txhawm rau kawm paub ntau ntxiv txog tus qauv kev ua haujlwm, nco ntsoov txheeb xyuas cov ntawv teev tseg ntawm Sparkfun cov khoom nplooj ntawv.

Kauj ruam 1: Mus Tau Cov Khoom

Koj yuav xav tau:

(x1) Cov ntaub thaiv npog ntawm tes (x1) Stackable Arduino headers (x1) Quad band antenna (x1) Arduino Uno

(Nco ntsoov tias qee qhov txuas ntawm nplooj ntawv no yog cov koom nrog sib txuas. Qhov no tsis hloov pauv tus nqi ntawm yam khoom rau koj. Kuv rov nqis peev nyiaj dab tsi uas kuv tau txais los ua cov haujlwm tshiab. Yog tias koj xav tau cov lus qhia rau lwm tus neeg xa khoom, thov qhia rau kuv paub.)

Kauj Ruam 2: Cov Taub Hau Solder

Ntxig cov headers rau hauv daim ntaub thaiv thiab muab lawv tso rau hauv qhov chaw.

Kauj ruam 3: Ntxig rau

Ntxig cov header pins rau hauv lub qhov (socket) ntawm Arduino.

Kauj ruam 4: Resolder

Tus kav hlau txais xov txuas rau SM5100B tus qauv feem ntau tsis zoo. Resolder txhua tus cable txuas rau tus qauv kom ntseeg tau kev sib txuas.

Kauj Ruam 5: Txuas tus kav hlau txais xov

Txuas tus kav hlau txais xov rau tus kav hlau txais xov cable.

Kauj Ruam 6: Ntxig SIM Card

Ntxig daim npav SIM kom ruaj ntseg rau hauv daim npav SIM.

Kauj ruam 7: Pib ua ntej

Xyuas kom tseeb tias cov qhab GSM raug xaiv raug xaiv rau koj lub tebchaws. Rau Asmeskas cov pab pawg yuav tsum tau teeb tsa rau 7. Txhawm rau teeb tsa pawg, siv cov lus txib no: AT+SBAND = 7 2.) Tom qab ua haujlwm ntawm Arduino nrog cov ntaub thaiv npog tau teeb tsa, txheeb xyuas tias tus qauv nyeem thiab lees paub SIM daim npav. Nrog lub qhov rai qhib siab thiab teeb tsa mus rau Arduino chaw nres nkoj thiab 9600 buad, lub zog ntawm Arduino. Qhov pib ua ntu zus yuav tsum zoo li no: Pib SM5100B Kev Sib Txuas … +SIND: 1 +SIND: 10, "SM", 1, "FD", 1, "LD", 1, "MC", 1, "RC", 1, "ME", 1 Kev sib txuas lus nrog tus qauv pib tom qab thawj kab tau tshwm. Kab thib ob ntawm kev sib txuas lus, +SIND: 10, qhia peb yog tus qauv tuaj yeem pom daim npav SIM. Yog tias daim npav SIM raug kuaj pom txhua lwm qhov chaw yog 1; yog tias daim npav SIM tsis pom nyob rau txhua qhov chaw yog 0. 3.) Tos kom muaj kev sib txuas hauv network ua ntej koj pib xa cov lus txib. Tom qab +SIND: 10 cov lus teb tus qauv yuav cia li pib sim txuas rau lub network. Tos kom txog thaum koj tau txais cov repsones hauv qab no: +SIND: 11 +SIND: 3 +SIND: 4 Cov +SIND cov lus teb los ntawm cov xov tooj ntawm tes qhia rau cov xwm txheej. Nov yog qhov nrawm nrawm ntawm cov lus teb lub ntsiab lus: 0 SIM daim npav tshem tawm 1 SIM daim npav tso 2 Lub suab paj nruag 3 AT module tau npaj ib nrab 4 AT module tau npaj txhij tag nrho 5 ID tso tawm hu 6 Tso tawm hu uas ID = 7 Lub network kev pabcuam yog muaj hu rau thaum muaj xwm txheej 8 Lub network ploj lawm 9 Suab ON 10 Qhia qhov xwm txheej ntawm txhua phau ntawv xov tooj tom qab pib kab lus 11 Sau npe rau network Tom qab sau npe hauv lub network koj tuaj yeem pib sib cuam tshuam. Nov yog qee qhov lus txib yooj yim thiab muaj txiaj ntsig kom pib: Txhawm rau hu: AT hais kom ua-ATDxxxyyyzzzz Tus lej xov tooj nrog hom ntawv: (xxx) yyy-zzz sim ---- cell.print ("ATDxxxyyyzzzz"); Yog tias koj hu xov tooj nco ntsoov siv cov ntaub ntawv xov tooj los txuas lub microphone thiab hais lus rau daim ntaub thaiv. Txhawm rau xa cov lus txt: AT hais kom ua - AT+CMGF = 1 Cov lus txib no teeb tsa cov ntawv xov xwm hom rau 'ntawv.' AT hais kom ua = AT+CMGS = "xxxyyyzzzz" (thauj rov qab) 'Cov ntawv xa' (CTRL+Z) Cov lus txib no tsis meej pem me ntsis los piav qhia. Tus lej xov tooj, hauv hom ntawv (xxx) yyy-zzzz nkag mus hauv ob nqe lus. Nias 'nkag' tom qab kaw cov lus hais tseg. Tom ntej no sau cov ntawv kom xa. Xaus qhov AT hais kom ua los ntawm kev xa CTRL+Z. Tus cim no tsis tuaj yeem xa los ntawm Arduino lub davhlau ya nyob twg. Siv lwm txoj haujlwm dav dav xws li Hyperterminal, Tera Term, Bray Terminal lossis X-CTU. SM5100B module tuaj yeem ua tau ntau dua li qhov no! Txheeb xyuas cov ntawv teev tseg ntawm nplooj ntawv khoom kom paub ntau ntxiv txog tus qauv.*/Qhib qhov chaw nres nkoj hauv lub davhlau ya nyob twg. Ntawm Mac qhov no ua tiav los ntawm kev ntaus ntawv: tshuaj ntsuam /dev/tty.usbmodemfa131 9600 (hloov tty.usbmodemfa131 nrog koj li Arduino tus lej chaw nyob) Tos kom pom cov ntu hauv qab no rov qab: Pib SM5100B Kev Sib Txuas … +SIND: 3 +SIND: 4 +SIND: 11 (Yog tias qhov xwm txheej no tsis rov qab los txheeb xyuas cov lej yuam kev teev nyob hauv qab ntawm cov cai saum toj no, thiab debug kom tsim nyog. +SIND 11)) Xa cov lus txib hauv qab no mus rau qhov chaw nres nkoj txuas: Xa qhov no rau North American siv: AT+SBAND = 7 Teem sijhawm tam sim no - yy/mm/dd: AT+CCLK = "13/05/15, 11: 02:00 "Xa daim ntawv xeem: ATD4155551212

Kauj Ruam 8: Cov Ntawv Xov Xwm

Rub tawm thiab teeb tsa SerialGSM rau hauv koj lub tsev qiv ntawv Arduino.

Txhawm rau xa xov tuaj ntsib Tronixstuff cellular module nyeem thiab siv piv txwv tus lej 26.3:

Yog tias koj xav khiav tus lej piv txwv kom tau txais cov ntawv, txuas lub LED rau tus pin 8 thiab muab tso ua ke nrog 220 ohm resistor rau hauv av.

Txhawm rau xa xov tuaj ntsib Tronixstuff cellular module nyeem thiab siv piv txwv tus lej 26.5:

Text ib qho ntawm cov lus txib hauv qab no rau koj lub xov tooj ntawm tes:

// tig lub LED ntawm #a1

// Tua lub LED tawm #a0

Kauj Ruam 9: Suab

Txuas lub microphone thiab tus hais lus rau daim ntaub thaiv uas siv cov kab hluav taws xob hauv av. Lub hauv paus teeb liab xaim yuav tsum mus rau lub suab ntxiv rau lub dav hlau thiab kev tiv thaiv yuav tsum mus rau qhov tsis zoo ib yam ntawm cov ntaub thaiv npog. Cov kab no yuav tsum txuas zoo ib yam ntawm lub microphone thiab sab tham.

Txhawm rau pib lub suab hu upload cov cai hauv qab no:
