Cov Lus Qhia Txog
Nta:
Tseg qhov muaj zog: 3.2V ~ 5.5V. (Yog hais tias tus module koj xav mus ua hauj lwm ntev teev hauv lub xeev emission, nws yog qhov pom zoo tias thaum lub qhov hluav taws xob muaj ntau tshaj 4.5V threaded ib kab 1N4007 kom tsis txhob muaj teeb tsa ua LDO built-in)
Qhov chaw nyob ntawm qhov chaw sib txawv (qhib qhov kev xeem): Txog 600m (qhov siab tshaj plaws kev sib txuas lus raug 1000m, qhov baud rate 5000bps)
Tuav teeb meem tam sim no: 16MA (Nyob rau hauv ntau hom kev ua hauj lwm hom tam sim no yog txawv)
Module qhov ntev: 27.8 x 14.4 x 4mm
Kev khiav hauj lwm ntau zaus: 433.4-473.0MHz, mus txog 100 raws kev sib txuas lus
Qhov siab tshaj plaws xa hluav taws xob: 100mW (settable)
Module yug software upgrade
Vim lub Hoobkas nqis: hom FU3, baud tus nqi yog 9600bps, kev sib txuas lus raws CH001 (433.4M)
AT hais kom ua:
Module tsis, AT hais kom ua
AT hais kom siv los teev cov ciaj ciam ntawm qhov function module thiab switching modules yuav tsum tawm ntawm qhov chaw hom tom qab qhov chaw rau kev siv. Meanwhile, hloov qhov tsis thiab kev ua haujlwm, lub zog-down tsis ploj.
Sau cov lus hais kom ua:
Thawj hom nkag - kev siv txwm (muaj lub hwjchim) nyob rau thawj 5-pin "SET" raug teeb tsa tsawg;
Qhov thib ob hom ntawm nkag - lub zog, tus thib 5 pin "SET" dua thawj teem tsawg rau lub hwj chim.
Ob txoj kev tuaj yeem ua tus module rau hauv AT hais kom ua hom, tso ("SET" tus pin tsis txuas nrog qis) tawm ntawm kev hais kom ua hom. Tom qab cov lus hais tawm hom, yog tias koj hloov qhov muaj nuj nqi module, qhov kev ua haujlwm yuav raug txiav rau lub xeev tsim nyog.
Qhov thib ob yog tsau rau hauv hom ntawv 9600, N, 1 rau hauv AT.
Lus Qhia:
1. AT
Cov lus qhia kev xeem
Piv txwv: Xa module rau "AT", lub module rov "OK".
2. AT + Bxxxx
Hloov qhov chaw nres nkoj ntawm qhov kev txiav txim cov lus sib tham. Koj tuaj yeem teev tus nqi baud yog 1200bps, 2400bps, 4800bps, 9600bps, 19200bps, 38400bps, 57600bps thiab 115200bps. Lub Hoobkas pheej muaj 9600bps.
Piv txwv: Teem caij rau qhov chaw nres nkoj ntawm qhov chaw nres nkoj baud rate yog 19200bps, thov xa cov lus txib hauv "AT + B19200"
"OK + B19200".
3. AT + Cxxx
Hloov txoj kab txuas kev sib txuas lus wireless, xaiv tau ntawm 001 rau 127 (ntau tshaj 100 xov tooj cua raws tom qab kev sib txuas lus tsis tau guaranteed). Cov nqi pheej yig yog 001 xov tooj cua raws, kev khiav hauj lwm zaus yog 433.4 MHz. Cov kauj ruam hauv kauj ruam yog 400KHz, kev khiav hauj lwm zaus ntawm cov channel 100 yog 473.0 MHz.
Piv Txwv:
Teem module rau channel 21, thov xa cov lus txib module "AT + C021", qhov module rov "OK + C021".
Tom qab tawm ntawm qhov hais kom ua hom, tus qauv nyob rau hauv thawj 21 raws, kev khiav hauj lwm zaus yog 441.4 MHz.
Ceebtoom: Vim tias lub tshuab txais receipt module HC-12 yog tus siab, cov baud tus nqi ntau dua thaum huab cua 58000 bps, 5 yuav tsum tau hloov mus rau cov dej uas nyob ib sab. Thaum twg cov paib baud rate tsis ntau dua 58000 bps, yog tias txoj kev sib txuas lus luv luv (10 meters), tab sis kuj yuav tsum tau ua kom poob siab tsib txoj kev siv channel.
4. AT + FUX
Hloov cov qauv ntawm kev dhau los ntawm hom kab ke, muaj FU1, FU2 thiab FU3 peb hom. Module default mode yog FU3, ob tug dhau kev dhau los ntawm hom module yuav tsum tau teem rau tib cov kev sib txuas lus. Saib cov ntsiab lus saum toj saud, "wireless serial pass-through".
Piv txwv: Xa module rau "AT + FU1", tus qauv rov qab "AT + OK".
5. AT + Px
Teem lub module xa cov xaim fais fab, x ntshaw 1-8, qhov coj ua ke xa tawm fais fab raws li nram no
Qhov chaw nyob yog 8, qhov siab tshaj plaws xa tawm fais fab, kev sib txuas lus ncua. Xa cov hwj huam qis yog teem rau 1, qhov qis zog tsawg tshaj plaws. Feem ntau, qhov kev sib kis ntawm txhua qhov poob 6dB, kev sib txuas lus yuav raug txo los ntawm ib nrab.
Piv txwv: Xa module rau "AT + P 5", lub module rov "OK + P5". Tom qab tawm qhov kev hais kom ua hom, tus module xa fais fab tuag yog +11 dBm.
X Tus nqi | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
Module xa fais fab (dBm) | -1 | 2 | 5 | 8 | 11 | 14 | 17 | 20 |
