Getting message while connecting to wi-fi as ESP not responding

[PeteKnight]

I don’t know where you obtained this sketch, but it’s a mess.

Some of the issues are…

@toytowncpt

SoftwareSerial EspSerial(0,1);

You’re defining a SoftwareSerial port called EspSerial, but you’re using the Uno’s hardware serial pins to do this.

@toytowncpt

#define ESP8266_BAUD 115200

The baud rate for the SoftwareSerial port used to communicate with the ESP-01 can’t use a baud rare faster than 9600 because that’s the maximum that the Uno is capable of using when emulating a serial port - because of the Uno’s poor processor speed.
This baud rate also needs to match that of the ESP-01.

@toytowncpt

  Serial.begin(115200);
  delay(10);
  Serial.begin(ESP8266_BAUD);

You are initialising the same Serial1 port (the hardware serial port of the Uno) twice.

@toytowncpt

Blynk.begin(auth, wifi, ssid, pass,"blynk-cloud.com", 8080);

blynk-cloud.com is the url for the old Legacy servers, which were decommissioned over a year ago.

I’d suggest you start by reading this topic…

Understanding hardware and software serial ports

I’m still seeing frequent posts, mostly from new members of the forum, who are confused about how to add WiFi or Bluetooth connectivity to devices like the Arduino Uno, Nano or Mega, or from people who are trying to use serial communication with some other type of peripheral. I thought I’d try to put together some guidance on how to do this properly. First things first though – if you’re using a device such as an Uno, Nano or Mega that doesn’t have built-in internet connectivity then you shoul…
