ESP8266-01 won't work with Blynk

So hey guys, I’ve got a problem:

I want to control my Arduino Mega 2560 via Smartphone, and I decided to do so with Blynk and an ESP8266-01. So far so good. I wired up the ESP and tried out serial communication – it worked out complete fine. But as soon as I try out an example code, the following error shows up:

[19]

__ 
/ )/ / ___ / /
/ / / // / \/ ‘/
/___//\, /////\\
/__/ v0.5.4 on Arduino Mega

[610] Connecting to <Here would be my W-Lan>

AT

[1620] ESP is not responding

AT+CIPCLOSE=1

AT+CIPCLOSE=1

AT+CIPSTART=1,“TCP”,“blynk-cloud.com”,80

Here’s the firmware of the ESP i found out during serial communication without Blynk:

AT version:1.3.0.0(Jul 14 2016 18:54:01)

SDK version:2.0.0(5a875ba)

Farylink Technology Co., Ltd. v1.0.0.2

So I was hoping somebody could help me,

Thanks in Advantage

Arduino using ESP as shield (AT firmware) is a common topic in this forum… and no need to go through yet another topic with all the diagnostic steps.

As required in the Community Polices, please search thoroughly before asking, as well as reading through all the documentation on this connection method.

Look for proper power options for the ESP, proper pin connection, proper use of the correct Serial methods (Hint, MEGA uses multiple hardware Serial options - no need for Software Serial), etc.

Then, if all else fails… please post the actual code you are using… properly formatted as per those policies in the link above :stuck_out_tongue_winking_eye:
