Khazikitsani IP / subnet mask / chipata

Adilesi ya IP ndi chizindikiritso cha module mu LAN, yomwe ili yapadera mu LAN, kotero sichingabwerezedwe ndi zipangizo zina mu LAN yomweyo. Adilesi ya IP ya module ili ndi njira ziwiri zopezera: static IP ndi DHCP / IP yamphamvu.
- static state IP
  Static IP iyenera kukhazikitsidwa pamanja ndi ogwiritsa ntchito. Mukukonzekera, samalani kulemba IP, subnet mask ndi chipata nthawi yomweyo. Static IP ndiyoyenera zochitika zomwe zimafunikira ziwerengero za IP ndi zida ndipo ziyenera kugwirizana chimodzi ndi chimodzi. Samalani ubale wofananira wa adilesi ya IP, chigoba cha subnet ndi chipata mukakhazikitsa. Kugwiritsa ntchito IP static kumafuna kukhazikitsa gawo lililonse ndikuwonetsetsa kuti adilesi ya IP siyibwerezedwa mkati mwa LAN komanso pazida zina zamaneti.
- DHCP / IP yamphamvu
  Ntchito yayikulu ya DHCP / IP yamphamvu ndikupeza ma adilesi a IP, adilesi ya Gateway, adilesi ya seva ya DNS ndi zidziwitso zina kuchokera pachipata, kuti mupewe zovuta zoyika adilesi ya IP. Zimagwira ntchito pazochitika zomwe palibe zofunikira za IP, ndipo sizifuna IP kuti igwirizane ndi ma modules amodzi ndi amodzi.
  Zindikirani: Gawoli silingakhazikitsidwe ku DHCP likalumikizidwa mwachindunji ndi kompyuta. Nthawi zambiri, kompyuta ilibe kuthekera kopereka adilesi ya IP. Ngati gawoli lakhazikitsidwa ku DHCP yolumikizidwa mwachindunji ndi kompyuta, gawoli likuyembekezera kutumizidwa kwa adilesi ya IP, zomwe zipangitsa kuti gawoli ligwire ntchito yopatsirana. Zosasintha za module ndi static IP: 192.168.0.7.
Chigoba cha subnet chimagwiritsidwa ntchito makamaka kudziwa nambala ya netiweki ndi nambala yolandila adilesi ya IP, kuwonetsa kuchuluka kwa ma subnets, ndikuweruza ngati gawolo lili mu subnet. Chigoba cha subnet chiyenera kukhazikitsidwa. Zomwe zimagwiritsidwa ntchito kwambiri m'kalasi C subnet chigoba: 255.255.255.0, nambala ya maukonde ndi yoyamba 24, chiwerengero cha khamu ndi otsiriza 8, chiwerengero cha maukonde ndi 255, gawo IP ndi mkati 255, gawo IP amaganiziridwa mu subnet iyi.
Gateway ndi nambala ya netiweki ya netiweki pomwe adilesi ya IP ilipo. Ngati chipangizocho ngati rauta chikulumikizidwa ndi netiweki yakunja, chipata ndi adilesi ya IP ya rauta. Ngati zochunira zili zolakwika, netiweki yakunja siyingalumikizidwe bwino. Ngati rauta sinalumikizidwe, palibe chifukwa choyiyika.

Bwezerani Zikhazikiko za Fakitale
Langizo la AT kuti mubwezeretse kuyika kwa fakitale: bwezeretsani fakitale kudzera pa AT + RESTORE. 6.2.3 Kusintha kwa Firmware
Njira yopititsira patsogolo firmware ya module ndikukweza kwakutali kwa OTA, ndipo pakukweza firmware, mutha kupeza ntchito zambiri.

Kusintha kwa firmware kumalumikiza netiweki kudzera mumsewu wama waya kapena wifi.
Opaleshoni GPIO2 pansi, yambitsaninso gawoli ndikulowetsamo OTA Mokweza.

Malizitsani kukweza, chotsani GPIO 2 pansi, yambitsaninso gawoli, ndipo gawolo likulowa mumayendedwe oyenera.

Kukhazikitsa ntchito kwa malangizo a AT
Wogwiritsa akhoza kulowa lamulo la AT kuti akhazikitse ntchito ya module. Onani ku esp32 mawaya module AT malangizo akhazikitsidwa kuti mudziwe zambiri.

Ntchito yotumizira deta
Gawoli lili ndi madoko anayi otumizira deta: doko la serial, wifi, Ethernet, ndi Bluetooth. Ogwiritsa ntchito amatha kuphatikiza ma doko anayi a data kudzera mu malangizo a AT a kufalitsa kwa data.
Konzani / funsani njira yotumizira gawoli kudzera mu malangizo a AT + PASSCHANNEL. Kukonzekera kwatha ndipo kumafuna gawo loyambitsanso kuti liyambe kugwira ntchito.

Ntchito ya socket
Njira yogwirira ntchito ya Socket ya module imagawidwa kukhala TCP Client, TCP Server, UDP Client, ndi UDP Server, yomwe ikhoza kukhazikitsidwa ndi malangizo a AT. Chonde onani gawo la esp32 chingwe AT command routine v 1.0.

TCP Client

TCP Client Amapereka kulumikizidwa kwa kasitomala pa ma network a TCP. Yambitsani mwachangu zopempha zolumikizirana ndikukhazikitsa zolumikizira ku seva kuti muzindikire kuyanjana pakati pa data ya serial port ndi data ya seva. Malingana ndi zofunikira za TCP protocol, TCP Client ndi kusiyana pakati pa kugwirizana ndi kuchotsedwa, motero kuonetsetsa kusinthanitsa kodalirika kwa deta. Nthawi zambiri amagwiritsidwa ntchito polumikizana ndi data pakati pa zida ndi ma seva, ndiyo njira yomwe imagwiritsidwa ntchito kwambiri polumikizirana pa intaneti.

Gawoli likalumikizidwa ndi TCP Server ngati TCP Client, liyenera kulabadira magawo monga chandamale IP / domain name ndi nambala yolowera. IP yomwe mukufuna ikhoza kukhala chipangizo chapafupi chokhala ndi dera lomwelo, kapena adilesi ya IP ya LAN yosiyana kapena IP pamanetiweki a anthu onse. Ngati seva ilumikizidwa pa netiweki yapagulu, seva imayenera kukhala ndi netiweki yapagulu IP.

Seva ya TCP
Nthawi zambiri amagwiritsidwa ntchito polumikizana ndi makasitomala a TCP mkati mwa LAN. Yoyenera LAN komwe kulibe ma seva ndi makompyuta angapo kapena mafoni am'manja amapempha deta kuchokera ku seva. Pali kusiyana pakati pa kugwirizana ndi kuchotsedwa monga TCP Client kuonetsetsa kusinthanitsa kodalirika kwa deta.

UDP Client

UDP Client Protocol yopatsirana yosalumikizidwa yomwe imapereka njira yosavuta komanso yosadalirika yotumizira uthenga wokhazikika pazochita. Popanda kukhazikitsidwa ndi kulumikizidwa, mumangofunika kupanga IP ndi doko kuti mutumize deta ku gulu lina. Nthawi zambiri amagwiritsidwa ntchito pazochitika zotumizira deta popanda kufunikira kwa mlingo wotayika wa paketi, mapaketi ang'onoang'ono ndi maulendo othamanga othamanga, ndi deta kuti iperekedwe ku IP yotchulidwa.

Seva ya UDP
Seva ya UDP Ikutanthauza kusatsimikizira magwero a IP adilesi pamaziko a UDP wamba. Pambuyo polandira paketi iliyonse ya UDP, IP yomwe mukufuna imasinthidwa kukhala IP source source IP ndi nambala ya doko. Deta imatumizidwa ku IP ndi nambala ya doko ya kulumikizana kwapafupi.

Mchitidwewu nthawi zambiri umagwiritsidwa ntchito potengera kufalitsa kwa data komwe zida zingapo zamaneti zimafunikira kulumikizana ndi ma module ndipo safuna kugwiritsa ntchito TCP chifukwa chakuthamanga komanso pafupipafupi…

Maphunziro a AT
Wogwiritsa akhoza kulowa lamulo la AT kuti akhazikitse ntchito ya module.

Kutumiza kwa serial port data
Kupyolera mu malangizo a AT, wosuta akhoza kupanga gawoli mu njira yotumizira deta, ndipo gawoli likhoza kusamutsa deta yosalekeza ku doko lofananira kumapeto (wifi, Ethernet ndi Bluetooth) kudzera pa njira yotumizira deta.

Bluetooth ntchito

Kutumiza kwa data kwa Bluetooth
Kupyolera mu ntchito ya Bluetooth yomwe ilipo ya gawoli, gawoli likhoza kupeza deta ya Bluetooth, ndipo lingathe kusamutsa deta ya Bluetooth kumalo otumizirana ma data (wifi, Ethernet ndi doko lachinsinsi) kudzera pa njira yotumizira.

Wifi ntchito

Kufikira pa intaneti
Module wifi yolumikizidwa ndi intaneti kapena netiweki yapafupi kudzera pa rauta, ndipo wogwiritsa ntchito amayenera kukonza socket ntchito kudzera mu malangizo a AT. Gawoli limatha kukhazikitsa kulumikizana kwa TCP / UDP, komwe kumatha kulumikiza seva yodziwika ya wogwiritsa ntchito.

Chingwe ndi network port access ntchito
Kulumikizana kwapaintaneti kokhazikika kumatha kupezeka kudzera pa netiweki yamawaya kuti muwonetsetse kupezeka kwa data yokhazikika pa intaneti.

Kufikira pa intaneti
Gawoli limalumikizidwa ndi intaneti kapena LAN kudzera pa intaneti ya waya, ndipo wogwiritsa ntchito amakonza socket ntchito kudzera mu malangizo a AT. Gawoli limatha kukhazikitsa kulumikizana kwa TCP / UDP ndikupeza seva yodziwika ya wogwiritsa ntchito.
