ESP01S (ESP8266) with Arduino Nano Clone, G9133 Regulator, 9g Servo: AT Commands Issue

I am building a WiFi-controlled servo project using an Arduino Nano clone, an ESP8266 (ESP01), a G9133 3.3 V voltage regulator, and a generic 9g micro servo. I just realized, it looks like the ESP01 is actually an ESP01S. I’m not sure if that changes anything.

I am coding it with the Arduino online code editor. Here is where I got the code/tutorial. All the code I used is supposed to do is set up the capability to use AT commands and send the AT+GMR command at the beginning.

Here is what is happening:

The LED on the ESP01 blinks once or twice on power up, but not again. Not sure if this is bad.
When sending AT commands, I just get “busy p… ERROR”
It is, however, able to send the AT+GMR command successfully once at the beginning (which it does in the code), but some of it is messed up.
These are the only baud rate settings I could get results with, shown in the picture of code. There is a picture of the serial monitor as well. I did include pictures of the physical circuit, but I don’t think that’s where the problem is.

Hello
Have you tried others cards?
And other computers?
Try to increment the delay pauses.
Check connections.

There are a few potential issues that could be causing the problems you are experiencing. Here are a few things to check:

Make sure that the baud rate of your serial connection between the Arduino and the ESP01 is set correctly. It looks like you have tried several different baud rates, but it is possible that you are still not using the correct baud rate.

Check the voltage level of the signal being sent from the Arduino to the ESP01. The ESP01 requires a 3.3V signal, and if the signal from the Arduino is too high, it could cause problems with communication. Make sure that the voltage regulator you are using is properly regulating the voltage to 3.3V.

Make sure that the wires connecting the Arduino to the ESP01 are properly connected and that there are no loose connections or damaged wires.

It is also possible that there is an issue with the ESP01 itself. You can try resetting the ESP01 by pressing and holding the reset button for a few seconds, or by power cycling the device. If the issue persists, it may be worth trying a different ESP01 to see if the problem is with the device itself.

Finally, it is worth noting that the ESP01S is an upgraded version of the ESP01, with additional flash memory and improved functionality. It is possible that the differences between the two models could be causing issues with your project, although it is difficult to say for sure without more information about your setup and the specific problems you are experiencing.
