Upload error Arduino Nano

[miene3]

Hello i try to upload this scetch to my Arduino nano but it doesn't work, have anyone a idea? i try to restart trhe software and my pc, but it still not working.
The error code is:
avrdude: ser_open(): can't set com-state for "\.\COM22"

And this is the Code:

In the Tools menu, when you select your board as Arduino Nano, look at the next setting below called Processor. Try changing this to "ATmega328P (Old Bootloader) and uploading your sketch again.

@miene3

can't set com-state for ".\COM22"

Is Serial Monitor in Arduino IDE open?

[ptillisch]

Hi @miene3. Please tell us which USB to serial adapter chip your Arduino board has. This is the largest black chip on the bottom of the board.

The chip will usually be identified by writing on the top. This might say something like "WCH CH340G" or "FTDI FT232RL".

Examples:

WCH CH340

If it isn't clear, alternatively you can provide the link to where you bought the board from and we'll see if we can determine the chip from the product listing.

[oskr0309]

The same thing happens to me, only that in the drive that it has, no nomenclature appears

[ptillisch]

Hi @oskr0309

@oskr0309

The same thing happens to me

I'm going to ask you to post some additional information that might help us to identify the problem.

---

This procedure is not intended to solve the problem. The purpose is to gather more information.

---

Please do this:

1. If you don't still have the IDE or web editor open with the error present, repeat the process that generated it.
2. You now need to copy the full and exact text of the output.
   The procedure for doing this is different depending on which Arduino development software you are using:
   • Arduino IDE 1.x: Click the Copy error messages button on the right side of the orange bar in the IDE.
   • Arduino IDE 2.x: Right click on the black "Output" panel at the bottom of the IDE window and then select "Copy All" from the context menu.
   • Arduino Web Editor: Click the icon that looks like two pieces of paper at the top right corner of the black console window Web Editor.
3. Open a forum reply here by clicking the Reply button.
4. Click the <CODE/> icon on the post composer toolbar.
   This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
   
5. Press Ctrl+V.
   This will paste the compilation output into the code block.
6. Move the cursor outside of the code block markup before you add any additional text to your reply.
7. Click the Reply button to post the output.

---

In case the output is longer than the forum software will allow to be added to a post, you can instead save it to a .txt file and then attach that file to a reply here:

1. Open any text editor program.
2. Paste the copied output into the text editor.
3. Save the file in .txt format.
4. Open a forum reply here by clicking the Reply button.
5. Click the "Upload" icon () on the post composer toolbar:
   
   A dialog will open.
6. In the dialog, select the .txt file you saved.
7. Click the Open button.
8. Click the Reply button to publish the post.

Alternatively, instead of using the "Upload" icon on the post composer toolbar as described in steps (5) - (7) above, you can simply drag and drop the .txt file onto the post composer field to attach it.

I see @oskr0309 created a dedicated topic for discussion of the upload error they are experiencing:

Avrdude: ser_open(): can't set com-state for "\\.\COM10"

Hi everyone, I'm new to this forum, I have an arduino nano and I can't upload a program. the question is that the pec recognizes the device as CH340 but in the arduino ID it throws me this avrdude: ser_open(): can't set com-state for "\.\COM10". I would appreciate your help, it is worth mentioning that on the arduino board the driver chip does not specify what type it is

I'll provide support over there.
