Qhov ntsuas ntsuas yog lub luag haujlwm los tsim thiab qhia qhov no ua ib qho rov qab.

Koj yuav tsum ntxiv cov lus txib ua ntej autoConnect !!!

Kauj Ruam 6: Sib dhos

Piv txwv

Hauv peb qhov piv txwv, peb yuav tsim Access Point nrog ESP (cov cai yuav ua haujlwm rau ESP8266 thiab ESP32). Tom qab tsim AP, peb yuav nkag mus rau lub portal los ntawm IP 192.168.4.1 (uas yog lub hauv paus nkag mus rau nws). Yog li cia peb tau txais cov network muaj, xaiv ib qho thiab txuag. Los ntawm qhov ntawd, ESP yuav rov pib dua thiab sim txuas rau nws, thiab tom qab ntawd nws yuav ua haujlwm raws li lub chaw nres tsheb thiab tsis yog Qhov Chaw Nkag Mus.

Tom qab nkag mus rau qhov chaw nres tsheb, koj tuaj yeem ua ESP rov qab mus rau Access Point hom nkaus xwb los ntawm khawm.

Kauj ruam 7: Code

Tsev qiv ntawv

Ua ntej cia peb txhais cov tsev qiv ntawv uas peb yuav siv.

Nco ntsoov tias peb muaj #if txhais, #else, thiab #endif cov lus txib. Lawv yog qhov muaj cai suav nrog cov tsev qiv ntawv tsim nyog ntsig txog lub nti. Qhov no yog qhov tseem ceeb tshaj plaws los ua tib txoj cai ntawm ob qho ESP8266 thiab ESP32.

#if txhais (ESP8266)

#include // ESP8266 Core WiFi Library #else #include // ESP32 Core WiFi Library #endif

#if txhais (ESP8266)

#include // Local WebServer siv los ua haujlwm teeb tsa portal

#lwm

#include // Local DNS Server siv rau kev xa rov qab txhua qhov kev thov mus rau kev teeb tsa portal (https://github.com/zhouhan0126/DNSServer---esp32)

#ib

#include // Local WebServer siv los ua haujlwm teeb tsa portal (https://github.com/zhouhan0126/DNSServer---esp32) #include // WiFi Configuration Magic (https://github.com/zhouhan0126/DNSServer-- -esp32) >> https://github.com/zhouhan0126/DNSServer---esp32 (ORIGINAL)

Kauj ruam 8: Teeb tsa

Hauv kev teeb tsa, peb tau teeb tsa peb li WiFiManager hauv txoj kev yooj yim tshaj plaws. Cia peb tsuas yog txhais cov callbacks thiab tsim lub network.

const int PIN_AP = 2;

teeb tsa tsis muaj dab tsi () {Serial.begin (9600); pinMode (PIN_AP, INPUT); // tshaj tawm objeto wifiManager WiFiManager wifiManager;

// utilizando esse comando, as configurações são apagadas da memória // caso tiver salvo alguma rede para conectar automaticamente, ela é apagada. // wifiManager.resetSettings (); // callback rau quando entra em modo de configuração AP wifiManager.setAPCallback (configModeCallback); // hu rov qab rau quando se conecta em uma rede, ou seja, quando passa a trabalhar em modo estação wifiManager.setSaveConfigCallback (saveConfigCallback); // cria uma rede de nome ESP_AP com senha 12345678 wifiManager.autoConnect ("ESP_AP", "12345678"); }

Kauj ruam 9: Loop

Hauv lub voj, peb yuav nyeem tus lej khawm kom pom tias nws tau raug nias, thiab tom qab ntawd peb yuav hu rau txoj hauv kev kom rov qhib tau hom AP.

void voj () {

WiFiManager wifiManager; // se o botão foi pressionado yog (digitalRead (PIN_AP) == HIGH) {Serial.println ("resetar"); // tenta abrir o portal yog (! wifiManager.startConfigPortal ("ESP_AP", "12345678")) {Serial.println ("Falha ao conectar"); ncua (2000); ESP.restart (); ncua (1000); } Serial.println ("Conectou ESP_AP !!!"); }

Thaum koj nias lub pob, ESP yuav tawm hom Chaw Nres Tsheb thiab qhib koj li Access Point thiab portal.

Nco ntsoov tias peb tsis siv qhov resetSettings () hais kom ua. Cov teeb tsa tseem raug cawm tseg rau lub sijhawm tom ntej ESP khau raj.

Kauj ruam 10: Hu rov qab

Lub luag haujlwm hu rov qab, uas cuam tshuam nrog cov xwm txheej, ua haujlwm rau koj kom muaj lub sijhawm tseeb ntawm kev ua haujlwm, hauv peb qhov xwm txheej, nkag mus rau AP hom thiab hom chaw nres tsheb. Peb tuaj yeem siv qee qhov niaj hnub xav tau, xws li rov qab SSID los ntawm kev sib txuas hauv network, piv txwv.

// callback que indica que o ESP entrou no modo AP

void configModeCallback (WiFiManager *myWiFiManager) {// Serial.println ("Nkag mus rau hom teeb tsa"); Serial.println ("Nkag mus rau qhov tsis muaj kev teeb tsa"); Serial.println (WiFi.softAPIP ()); // luam tawm IP ua AP Serial.println (myWiFiManager-> getConfigPortalSSID ()); // luam tawm lossis SSID criado da rede

}

// callback que indica que salvamos uma nova rede para se conectar (modo estação)

void saveConfigCallback () {// Serial.println ("Yuav tsum txuag kev teeb tsa"); Serial.println ("Configuração salva"); Serial.println (WiFi.softAPIP ()); // luam tawm lossis IP rau AP}
