ESP8266-01 with Arduino Uno, problem with WIFI connection

[lw3eov]

Hello Community,

I am using a ESP8266-01 connected to an arduino uno as it can be seen here: esp01-connections hosted at ImgBB — ImgBB

I uploaded a blank sketch to the arduino and I am able to run all this AT commands and even connect succesfully to wi-fi as I can see in the Arduino IDE's serial monitor: ATOK-------------------------------------------------Returns MACAT+CIP - Pastebin.com

After that I moved the pins 2 and 3 to 7 and 6 and I used an online graphical site for coding where I can download the generated files: www.arduinoblocks.com

The problem is when the arduino tries to connect to wifi this happens (as I can see this in the IDE's serial monitor):

⸮[WiFiEsp] Initializing ESP module
[WiFiEsp] >>> TIMEOUT >>>
[WiFiEsp] Initilization successful - 2.0.0
Attempting to connect to WPA SSID: Atomos
[WiFiEsp] >>> TIMEOUT >>>
[WiFiEsp] Failed connecting to Atomos
Attempting to connect to WPA SSID: Atomos
[WiFiEsp] Connected to Atomos
Attempting to connect to WPA SSID: Atomos
[WiFiEsp] Connected to Atomos

and it keeps going like that... Maybe I can add some lines to the code so I can have more feedback to see exactly what is the problem? I suppose it can be that the module does not get an IP but how I can be sure?

Here is the .ino file: /* ArduinoBlocks.com *//* Project: wifi */#include <SoftwareSerial.h># - Pastebin.com

I also have this other 26 files that come with it (the numbers before the file names are the sizes in kb): m@m:~/Desktop/arduinoblocks553928$ ls -stotal 192 4 ABlocksIOTArduinoDefines - Pastebin.com

I uploaded them here as a single .zip file: 40.6 KB file on MEGA

But if you prefer I can put them in pastebin or provide them in some other way. I did not put them here as it will be too long.

Many thanks

Marcelo

Here is the .ino file:

You can post that here.
Personally i don't support the use of AT-commands initiated from a sketch a different machine (like a Mega)
It is to cumbersome and inefficient compared to programming the ESP directly.

OK Deva_Rishi, I am posting the .ino file here as you suggested:
