Basic functions
Teem lub IP / subnet npog / rooj vag
- Tus IP chaw nyob yog tus neeg sawv cev ntawm tus qauv hauv LAN, uas yog qhov tshwj xeeb hauv LAN, yog li nws tsis tuaj yeem rov ua dua nrog lwm cov khoom siv hauv tib LAN. IP chaw nyob ntawm module muaj ob txoj kev tau txais: IP zoo li qub thiab DHCP / dynamic IP.
- static xeev IP
Static IP yuav tsum tau teeb tsa manually los ntawm cov neeg siv. Nyob rau hauv tus txheej txheem ntawm kev teeb tsa, them sai sai rau sau IP, subnet npog thiab lub rooj vag tib lub sijhawm. Static IP yog qhov tsim nyog rau cov xwm txheej uas xav tau cov txheeb cais ntawm IP thiab cov khoom siv thiab xav tau sib txuas ib rau ib qho. Ua tib zoo saib xyuas qhov sib raug zoo ntawm IP chaw nyob, subnet mask thiab lub rooj vag thaum teeb tsa. Kev siv tus IP zoo li qub yuav tsum tau teeb tsa rau txhua qhov module thiab xyuas kom meej tias IP chaw nyob tsis rov ua dua hauv LAN thiab ntawm lwm cov khoom siv hauv network. - DHCP / dynamic IP
Lub luag haujlwm tseem ceeb ntawm DHCP / dynamic IP yog dynamically tau txais IP chaw nyob, Gateway chaw nyob, DNS neeg rau zaub mov chaw nyob thiab lwm yam ntaub ntawv los ntawm lub rooj vag tus tswv, thiaj li zam lub cumbersome cov kauj ruam ntawm kev teeb tsa IP chaw nyob. Nws muaj feem xyuam rau cov xwm txheej uas tsis muaj qhov yuav tsum tau ua rau IP, thiab nws tsis tas yuav IP kom sib haum rau cov modules ib qho los ntawm ib qho.
Nco tseg: Lub module tsis tuaj yeem teem rau DHCP thaum txuas ncaj qha rau lub computer. Feem ntau, lub computer tsis muaj peev xwm muab IP chaw nyob. Yog tias lub module raug teeb tsa rau DHCP ncaj qha txuas nrog lub khoos phis tawj, lub module yuav tos rau qhov chaw nyob IP, uas yuav ua rau lub module ua haujlwm sib kis tau zoo. Lub module default yog zoo li qub IP: 192.168.0.7.
- static xeev IP
- Lub npog ntsej muag subnet feem ntau yog siv los txiav txim siab tus lej xov tooj thiab tus tswv tsev ntawm tus IP chaw nyob, qhia tus lej ntawm subnets, thiab txiav txim seb lub module puas nyob hauv subnet. Lub npog ntsej muag subnet yuav tsum tau teeb tsa. Cov chav kawm C subnet feem ntau siv: 255.255.255.0, tus naj npawb network yog thawj 24, tus tswv tsev tus lej yog 8 kawg, tus lej ntawm tes hauj lwm yog 255, module IP yog nyob rau hauv 255, module IP yog suav tias yog nyob rau hauv no subnet.
- Gateway yog tus lej xov tooj ntawm lub network uas qhov chaw nyob IP tam sim no nyob. Yog tias lub cuab yeej zoo li lub router txuas nrog lub network sab nraud, lub rooj vag yog IP chaw nyob ntawm router. Yog tias qhov teeb tsa tsis raug, lub network sab nraud tsis tuaj yeem txuas tau raug. Yog tias lub router tsis txuas nrog, tsis tas yuav teeb tsa nws.
Restore lub Hoobkas nqis
AT cov lus qhia kom rov kho lub Hoobkas: rov ua lub Hoobkas los ntawm AT + RESTORE. 6.2.3 firmware upgrade
Txoj hauv kev los txhim kho lub module firmware yog OTA tej thaj chaw deb hloov kho, thiab los ntawm kev kho dua tshiab firmware, koj tuaj yeem tau txais ntau daim ntawv thov ua haujlwm.
- Lub firmware txawj tej yam ntxiv txuas lub network los ntawm ib tug wired txoj kev los yog ib tug wifi.
- Kev ua haujlwm GPIO2 hauv av, rov pib lub module thiab nkag mus rau OTA hloov kho hom.
- Ua kom tiav qhov kev hloov kho tshiab, tshem tawm GPIO 2 mus rau hauv av, rov pib dua lub module, thiab lub module nkag mus rau hom kev ua haujlwm ib txwm muaj.
Kev ua haujlwm ntawm AT cov lus qhia
Tus neeg siv tuaj yeem nkag mus rau AT cov lus txib los teeb tsa cov haujlwm ntawm lub module. Xa mus rau esp32 wired module AT cov lus qhia kom paub meej.
Cov ntaub ntawv kis tau tus mob muaj nuj nqi
Lub module muaj plaub qhov chaw xa cov ntaub ntawv: serial chaw nres nkoj, wifi, Ethernet, thiab Bluetooth. Cov neeg siv tuaj yeem muab plaub qhov chaw nres nkoj los ntawm AT cov lus qhia rau cov ntaub ntawv xa mus.
Teem / nug cov kis tau tus mob ntawm lub module los ntawm AT + PASSCHANNEL cov lus qhia. Kev teeb tsa tiav lawm thiab yuav tsum tau rov pib dua module kom siv tau.
Lub qhov (socket) ua haujlwm
Lub qhov (socket) ua haujlwm hom ntawm lub module tau muab faib ua TCP Client, TCP Server, UDP Client, thiab UDP Server, uas tuaj yeem tsim los ntawm AT cov lus qhia. Thov xa mus rau esp32 cable module AT command routine v 1.0.
TCP Cov Neeg Siv Khoom
- TCP Client Muab cov neeg siv khoom sib txuas rau TCP cov kev pabcuam network. Ua haujlwm pib thov kev sib txuas thiab tsim kev sib txuas rau lub server kom paub txog kev sib cuam tshuam ntawm cov ntaub ntawv chaw nres nkoj thiab cov ntaub ntawv server. Raws li cov kev cai cuam tshuam ntawm TCP raws tu qauv, TCP Client yog qhov sib txawv ntawm kev sib txuas thiab kev sib txuas, yog li ua kom ntseeg tau qhov kev sib pauv cov ntaub ntawv. Feem ntau siv rau cov ntaub ntawv sib cuam tshuam ntawm cov khoom siv thiab cov servers, nws yog txoj kev siv ntau tshaj plaws ntawm kev sib txuas lus hauv network.
- Thaum lub module txuas nrog TCP Server li TCP Client, nws yuav tsum tau them sai sai rau qhov tsis xws li lub hom phiaj IP / domain name thiab lub hom phiaj chaw nres nkoj. Lub hom phiaj IP tuaj yeem yog cov cuab yeej hauv zos nrog tib cheeb tsam hauv zos, lossis tus IP chaw nyob ntawm LAN sib txawv lossis IP thoob plaws hauv zej zog. Yog tias tus neeg rau zaub mov txuas nrog thoob plaws lub network pej xeem, tus neeg rau zaub mov yuav tsum muaj IP network pej xeem.
TCP Server
Feem ntau siv rau kev sib txuas lus nrog TCP cov neeg siv khoom hauv LAN. Haum rau LAN qhov twg tsis muaj servers thiab ntau lub khoos phis tawj lossis lub xov tooj ntawm tes thov cov ntaub ntawv los ntawm lub server. Nws muaj qhov sib txawv ntawm kev sib txuas thiab kev tsis sib txuas raws li TCP Client kom ntseeg tau tias muaj kev sib pauv cov ntaub ntawv.
UDP Client
UDP Client Ib qho kev sib txuas uas tsis txuas nrog cov txheej txheem uas muab cov ntaub ntawv yooj yim thiab tsis ntseeg tau cov kev pabcuam xa mus rau kev lag luam. Yog tsis muaj kev sib txuas thiab kev sib txuas, koj tsuas yog yuav tsum ua tus IP thiab chaw nres nkoj xa cov ntaub ntawv mus rau lwm tus neeg. Nws feem ntau yog siv rau cov ntaub ntawv kis tau tus mob uas tsis tas yuav tsum tau rau pob ntawv poob tus nqi, pob ntawv me me thiab kis ceev ceev, thiab cov ntaub ntawv xa mus rau tus IP teev.
UDP Server
UDP Server txhais tau tias tsis txheeb xyuas qhov chaw nyob IP raws li qhov zoo tib yam UDP. Tom qab tau txais txhua pob ntawv UDP, lub hom phiaj IP raug hloov mus rau cov ntaub ntawv qhov chaw IP thiab tus lej chaw nres nkoj. Cov ntaub ntawv raug xa mus rau tus IP thiab tus lej chaw nres nkoj ntawm kev sib txuas lus ze tshaj plaws.
Hom no feem ntau yog siv rau cov ntaub ntawv kis tau tus mob qhov twg ntau lub network li xav tau kev sib txuas lus nrog modules thiab tsis xav siv TCP vim lawv ceev ceev thiab zaus… Serial chaw nres nkoj muaj nuj nqi
