WiFiManager VS pubsubclient

Hello. Some time ago I' ve strugled with seting up wifi manager in esp_idf framework. Most popular wifi manager made by tzapu was not working on esp-idf framework inside PlatformIo. So I have found tonyp7. It started to work after many changes in library code and makefiles. I have some free time and I can make WifiManager suited to bare esp-idf and esp-idf inside PlatformIo. My question is- do somebody need this ? Maybe there are alternatives which i did not find and my work is pointless. Please share your opinion

Is that fork needed still? It seems like the main project claims support for esp32 now? https://github.com/tzapu/WiFiManager

I use WifiManager (https://github.com/tzapu/WiFiManager) .. it will setup the device as an access point you connect to and configure the wifi.

Reminds me of this. I will try it out.

WifiManager (https://github.com/tzapu/WiFiManager or https://registry.platformio.org/libraries/khoih-prog/ESP_WiFiManager_Lite):

If you have other code that does not rely on being connected to WiFi I would look into running WiFi manager in none blocking mode. There is an example here: https://github.com/tzapu/WiFiManager/blob/master/examples/NonBlocking/AutoConnectNonBlocking/AutoConnectNonBlocking.ino

// I won't hide these informations bellow because this is just a test. You can compile on your esp32 #define BLYNK_TEMPLATE_ID "TMPLc9VK-ym3" #define BLYNK_DEVICE_NAME "Wifi Bluetooth ESP32 DHT Station" #define BLYNK_AUTH_TOKEN "IzH-vvhVf0uLJaV54Ziero7kjUiFeq5g" #include // https://github.com/tzapu/WiFiManager #include #define TRIGGER_PIN 22 #define LED_PIN 23 TaskHandle_t Task1; int timeout = 120; unsigned long blink_timer; char auth[] = BLYNK_AUTH_TOKEN; WiFiManager wm; void wifi_stuff( void * pvParameters ){ Serial.print("wifi_stuff running on core "); Serial.println(xPortGetCoreID()); for(;;){ if(!Blynk.connected()){ wm.autoConnect(); Blynk.config(auth); Blynk.connect(5000); } if ( digitalRead(TRIGGER_PIN) == LOW) { WiFiManager wm; wm.resetSettings(); wm.setConfigPortalTimeout(timeout); if (!wm.startConfigPortal("OnDemandAP")) { Serial.println("failed to connect and hit timeout"); } wm.setEnableConfigPortal(false); } } } void setup() { WiFi.mode(WIFI_STA); // explicitly set mode, esp defaults to STA+AP Serial.begin(115200); Serial.println("\n Starting"); pinMode(TRIGGER_PIN, INPUT_PULLUP); pinMode(LED_PIN, OUTPUT); wm.setEnableConfigPortal(false); wm.autoConnect(); Blynk.config(auth); Blynk.connect(5000); //blynk connect timeout xTaskCreatePinnedToCore( wifi_stuff, /* Task function. */ "Task1", /* name of task. */ 10000, /* Stack size of task */ NULL, /* parameter of the task */ tskIDLE_PRIORITY, /* priority of the task */ &Task1, /* Task handle to keep track of created task */ 0); } void loop() { Blynk.run(); //bellow is for debug if (millis() - blink_timer > 300){ digitalWrite(LED_PIN, !digitalRead(LED_PIN)); blink_timer = millis(); Serial.println(Blynk.connected()); } }

Oh and if you're implementing it yourself and want a captive portal look into WifiManager. It's pretty much the standard ESP captive portal.

I got the built in LED blinking within a couple minutes. (Great Success! :D ) I haven't done as well with MQTT. :-/ I started following a tutorial at https://vimalb.github.io/IoT-ESP8266-Starter/Lesson_04/lesson.html and immediately ran into the header PubSubClient.h not found. I went into Tools -> Manage Libraries, entered "MQTT" in the search field and came up with over 30 libraries! Next I did a search for the missing header error message and that led me to https://github.com/Imroy/pubsubclient. I installed that and it gets me past the missing header, but when I try to create a PubSubClient I get error: no matching function for call to 'PubSubClient::PubSubClient()' which means there is no default constructor for this class. So I'm not sure if I have the wrong library or if it has been modified since the tutorial was written.
