Esp is not responding-arduino-esp01s

It is important for me to say that i tried 3 diffrent ones… all got the same error.
I also wanted to say that it worked. It worked fine. And then became unstable and stopped.

Arduino UNO with Esp01s
Blynk Library version 1.10
Connections:
esp01s arduino
tx---------------->pin2
rx---------------->pin3
3.3v------------->3.3v power supply arduino/external will detail ahead
ground--------->ground / external grouns
ch enable ----->3.3v

tried both arduino power source and external one.
will post the details of the one I found. wondering if it fitts.
baud rate both at 9600.
still getting the error message as you can see in the details ahead.
will add a the firmware of at version and also baud rate for proof.

/*************************************************************
  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

  You’ll need:
   - Blynk IoT app (download from App Store or Google Play)
   - Arduino Uno board
   - Decide how to connect to Blynk
     (USB, Ethernet, Wi-Fi, Bluetooth, ...)

  There is a bunch of great example sketches included to show you how to get
  started. Think of them as LEGO bricks  and combine them as you wish.
  For example, take the Ethernet Shield sketch and combine it with the
  Servo example, or choose a USB sketch and add a code from SendData
  example.

I can’t see anything obviously wrong with your setup, but I am curious about how you’ve produced what you call your “AT setup”?

Is the WiFi SSID that you’re using 2.4GHz?

Have you tried removing the stepper motor library and code from the sketch and physically disconnecting the motor from your Uno?

TBH, I can’t understand why people continue to use the Uno/Mega/Nano + ESP-01 combination anymore. It’s prehistoric technology that should be obsolete by now.

Hi Pete, thanks for the answer.
when deleted everthing related to the motor it worked.

failed to enable mux? critical?
hope it will be stable.
i do want to use the motor… maybe the line in the setup void made this mess? (i checked - moved the line form the set up void, didnt help, it is all or nothing - hope yo may help me)
the network is 2.4ghz.

i dont mind moving on, any suggestion?

thank you a lot.

No, it’s common and doesn’t seem like a problem.

It’s probably the motor library that you’re using that’s causing the problem. Try a different library.

If you’re looking for a more modern board then tge ESP32 is probably your best option.

Pete.
