Problem with wifi manager

proietti · June 5, 2019, 8:50pm

The weirdest thing, i have written a sketch for dimming up and dimming down leds using FadeLed library. Everything works well as when i am not using wifi manager. As soon as i insert the wifi manager stuff it disconnects and does not reconnect. Am i missing something? The wifi code used is the same as i have used for other projects and they work well…

I’m no expert on how wifiManager actually works. So usually I try to copy it exactly as the github example shows. It looks like you are missing a configFile.close(); in the mounting FS portion of the code. Not sure if this is what is causing your problem, but may be worth giving a try. IMO the serial prints are very handy in trying to debug a piece of code, not sure why you decided to leave them out.

//read configuration from FS json
  Serial.println("mounting FS...");

  if (SPIFFS.begin()) {
    Serial.println("mounted file system");
    if (SPIFFS.exists("/config.json")) {
      //file exists, reading and loading
      Serial.println("reading config file");
      File configFile = SPIFFS.open("/config.json", "r");
      if (configFile) {
        Serial.println("opened config file");
        size_t size = configFile.size();
        // Allocate a buffer to store contents of the file.
        std::unique_ptr<char[]> buf(new char[size]);

        configFile.readBytes(buf.get(), size);
        DynamicJsonBuffer jsonBuffer;
        JsonObject& json = jsonBuffer.parseObject(buf.get());
        json.printTo(Serial);
        if (json.success()) {
          Serial.println("\nparsed json");

          strcpy(mqtt_server, json["mqtt_server"]);
          strcpy(mqtt_port, json["mqtt_port"]);
          strcpy(blynk_token, json["blynk_token"]);

        } else {
          Serial.println("failed to load json config");
        }
        configFile.close(); //YOU ARE MISSING THIS
      }
    }
  } else {
    Serial.println("failed to mount FS");
  }
//end read

I will try this. I left out the serial prints just to shorten the code for uploading to the forum

PeteKnight · June 6, 2019, 6:02am

Always a bad idea!
I’ve lost count of the number of wasted hours because someone wasn’t running exactly the same code that they posted.

Pete.

proietti · June 6, 2019, 8:57am

I only took out the serial prints of the wifi manager which are the standard from the wifi manager

proietti · June 6, 2019, 10:19am

Ok i think the issue is with the Fadeled.h library. Some type of conflict. I have tried the wifi manager code with all my other projects and it works. with this one at setup on the wifi manager interface you connect then 2 seconds later disconnects and does not reconnect???

PeteKnight · June 6, 2019, 1:18pm

I do recall a thread about 12-18 months ago with a FastLED library issue, but I can’t find it now.

If you’re not run I g the latest FastLED library then upgrade. If you are running the latest then downgrade!

Also play around with the ESP core version you’re using. Anything later than 2.4.2 can be dodgy sometimes.
