Hi my computer is not recognizing my esp Node32s does anyone have any suggestions?

Can you provide more information, source code, error messages, wiring diagram would be a start.

@zander I was following this video Introduction to ESP32 - Getting Started (youtube.com) and my computer would not even recognize my ESP as a device.

@josiah430 And?

There are 10 sketches in that video, which is not working for you?

It will greatly help if you would post the code here so I can try it. If the code is wrong it will fail for me too, otherwise it's something you have done in error.

@zander It was a brand new ESP and I was just trying to connect to my computer. I was not working on any project.

@josiah430 I'm sorry, am I not speaking clearly? What do you mean exactly, is the USB cable not able to connect to the ESP32? Or are you loading a sketch and uploading it but the result you expected isn't happening.

Tell us EXACTLY what you did.

1. brought sketch WiFi scanner into IDE.

2. Uploaded to esp32 with no errors.

3. There are NO messages, or there are, show them to us.

I have dozens of esp32's and many hours of experience, but so far all I know is you have an esp32 and a computer and nothing else.

@zander

 

1. Opened the Arduino ide

2. pasted the Json file link into "Additional Boards Manager URLs" under preferences.

3. Installed the ESP32 board manager.

4. Plugged in the ESP32. Once I plug it in it makes the sound that I have plugged in a device. But There was no comport listed for the ESP I had just plugged in.

@josiah430 Ok. First, close the IDE and restart. Then select your board (it can be a generic, I usually use  DOIT as my search argument) and if the board is plugged in, select the port.

IF as often happens, you don't see a port, unplug and try a different USB.

One of the reasons I dumped Windows for Apple was windows device manager screw-ups.

Good luck.

@josiah430 Ok, it is something that happens quite a bit for some folks, just be patient and try again.

Which Arduino Ide would you recommend me to use 1.8 or 2.3?

@josiah430 Some folks like the old 1.8, some the new 2.3. I like 2.3. At first it seemed foreign, but now I enjoy all it's extra features and don't miss whatever it was lacking (I can't even remember now). Once you have 10 posts, I will PM you some semi-secret settings you may also want to try.

@zander In the Arduino IDE, it does not appear as a device or COM port after trying your advice. Although if I open the device manager on my computer it appears as "CP2102 USB to UART Bridge Controller".

Esp32

 

Do you have any other ideas before I get a replacement ESP?

@josiah430 That is the chip/device that is attached to the USB port. Did you click it?
