Teensy 4.0 and esp 8266 01

Need Help With My Project

Hi i am having problem with connecting teensy 4.0 and esp8266 01 to the blynk app. I am using blynk.ncp example to connect esp with blynk, but connection last just a minute or two and then disconnect. Did somebody try to connect esp 01 with boards that are not presets? Can somebody help me…

This is code:

      SerialDbg.println(F("NCP: Button was released => configuration is reset"));
      break;
    default: break;
    }
}

and this is what serial monitor gives me:

Blynk.NCP ready, baud: 230400
NCP firmware: 0.6.3
NCP state: Configuration

@Zac7 Please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code and serial output so that they display correctly.
Triple backticks look like this:
```

Copy and paste these if you can’t find the correct symbol on your keyboard.

Pete.
