[1619] Failed to disable Echo

First of all; yes I read all posts about this issiue.

I spent 2 days on this but no hope. So here I’am.

I’m using;

  • Arduino Uno with ESP01 circuit.
  • Ide 1.6.8
  • blynk lib 0.4.3
  • firmware AT22SDK10020150320boot1.2.bin

I update like 10 firmwares this is the only one works on serial AT commands.
I set the baudrate 9600 for my ESP (cuz I’m using softwareserial)

#include <SoftwareSerial.h>
SoftwareSerial EspSerial(2, 3); // RX, TX

// Your ESP8266 baud rate:
#define ESP8266_BAUD 9600

ESP8266 wifi(&EspSerial);

-Connected RX,TX to pin 2,3 (tried reverse too)
-Used good power supply.

Any ideas?

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

i have same problem, i still did not solve

Easiest fix is to use a decent ESP (not the limited 01) and drop the Uno.
