Hi, I am doing a project using the ESP 8266 as a Sheild with the Arduino Uno. I am following the Blynk Docs Tutorial to connect it. After Setting the Baud Rate to 9600 and connecting the TX and RX pins in the Serial Monitor I got.
As you can see I get that the ESP is connected but I don’t get Ready and the App still shows as not connected. What can I do? I am using a 3.3V Regulator so I don’t think it is a Power Supply Issue. The Only Questionable thing is that I am using a breadboard to connect everything.
Has anyone ever got this error or is it just me. I am also using the 1.5.4 Firmware for the ESP-01. I also tried the same ESP as Standalone and it worked. This is the code I am using. What should I try next?

This example shows how to use ESP8266 Shield (with AT commands)
to connect your project to Blynk.
WARNING!
It's very tricky to get it working. Please read this article:
http://help.blynk.cc/hardware-and-libraries/arduino/esp8266-with-at-firmware
Change WiFi ssid, pass, and Blynk auth token to run :)
Feel free to apply it to any other example. It's simple!
