[Solved] Failed to disable echo{1619} January 2017

   #define BLYNK_PRINT Serial    // Comment this out to disable prints and save space
#include <ESP8266_Lib.h>
#include <BlynkSimpleShieldEsp8266.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "auth";

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "Dreamerz";
char pass[] = "pass";

// Hardware Serial on Mega, Leonardo, Micro...
#define EspSerial Serial

// or Software Serial on Uno, Nano...
//#include <SoftwareSerial.h>
//SoftwareSerial EspSerial(2, 3); // RX, TX

// Your ESP8266 baud rate:
#define ESP8266_BAUD 9600

ESP8266 wifi(&EspSerial);

void setup()
{
  // Set console baud rate
  Serial.begin(9600);
  delay(10);
  // Set ESP8266 baud rate
  EspSerial.begin(ESP8266_BAUD);
  delay(10);

  Blynk.begin(auth, wifi, ssid, pass);
}

void loop()
{
  Blynk.run();
}   

plz help error.

[UPD: “Failed to disable echo” will most probably be reported as “ESP is not responding” now]

Do you have USB 2 TTL adaptor wired up to your Uno?

Your problem was covered 7 posts before yours, see [SOLVED] ESP8266 as a wifi shield of Arduino Uno to control a 6 channel Relay

no but i can use my arduino uno and remove its atmega 328p and flash the same code on my nano.

Same problem with the Nano, just one Serial port.

Look through the link I provided.

what i am trying to say is that i can use my uno as a serial converter ttl and monitor the same code flashed on my nano

Yes I believe Arduino’s can be used as USB 2 TTL adaptors.
Let us know how it goes.

okay

i have managed to load the code onto a arduino nano and use arduino uno(without the atmega 328p-pu) as usb ttl converter and it works!!!

That is excellent news @Sai_Khurana

Presumably you are using 2 USB ports, one for the Arduino Nano as MCU and one for the Uno as a USB 2 TTL adaptor, correct?

For others I have detailed 3 ways to use Arduino’s as USB 2 TTL adaptors

  1. If the chip can be removed take it out
    or
  2. Wire reset and GND together
    or
  3. Flash this sketch
void setup(){
  pinMode(0,INPUT);
  pinMode(1,INPUT);
}
void loop(){
}

yeah sort off.
actually my arduino nano’s ch340 chip was brokrn when i bought it. so i de-soldered it and used a usbasp to program it.

I have the same problem… Can somebody help??
"failed to disable echo "

Please stick to one post and/or thread.

Sorry :see_no_evil:
