After AutoConnect esp8266 not can to connect to Blynk cloud

Need Help With My Project

Hi, blynkers. I need help.

NodeMCU esp8266, Arduino IDE 1.6.8, Blynk library 0.3.10

In my project I use WiFiManager library.
My probleme - after connection to the my network via WiFi esp8266 can’t connect to the Blynk cloud.

wifi.autoConnect("Blynk");
String ssid = wifi.getSSID();

Blynk.begin(auth, ssid.c_str(), pass.c_str());
while (Blynk.connect() == false) 
    {
        // Wait until connected
    }


delay(1000);
//setup pins
for (int i = 0; i < 4; i++)
    {
    pinMode(ValvePins[i], OUTPUT);    
    digitalWrite(ValvePins[i], LOW);  
    delay(10);
    }
 rtc.begin();
//setup timers
timer.setInterval(10000L, clockDisplay);

Serial.println("done setup");
}

//Main loop*************

{
//blynk connect and run loop
Blynk.run();
//timer run loop
timer.run();
}

This shows messages on terminal:

On smartphone Blynk Ap periodicaly appears message:

If in Setup instead wifi.autoConnect(“AutoConnectAP”); I use function
Blynk.begin(auth, ssid, pass); then connection to the Blynk is successfully.

What is not properly?

Lots of things but let’s start with this fix In case you see SMTHNG strange in Blynk - #8 by Costas

@klg you can’t simply add backticks to a badly formatted piece of code and it display correctly.

Procedure is:

3 backticks
paste formatted code (replace token with xxxx)
3 backticks

Did you try to compile your sketch?

In the badly formatted version you don’t have the #'s before the defines and includes. The includes are missing opening <'s etc.

ValvePins hasn’t been declared.

wifi.getSSID can’t be retrieved from WiFi Manager and neither can wifi.getPassword.

If all you want WiFiManager to do is connect you to a router all you need in the start of setup() is:

  wifi.autoConnect("AutoConnectAP");
  Serial.println("\nconnected");
  Blynk.config(auth, "192.168.10.229");
  while (Blynk.connect() == false) 
  {
      // Wait until connected
  }

Note, Blynk.config not Blynk.begin as detailed in the comprehensive notes, because begin tries to connect to a router but you have already done that with WiFiManager.
