What should I do, this is what it says when I try and upload it please respond.

This sounds like a bad USB cable but it could also be a generic flashing problem (not deauther related).

Please specify the device you're using and how it's wired when flashing, eventually post a pic of your build so we can see the wiring.

I'm using a nodemcu not sure which version it is, and I tried two other cable but it still didn't work. And what should I do if it is a generic flashing problem (ps I'm using arduino to upload the program)

[tobozo]

Eventually push the flash button while Arduino is compiling and keep it pushed until you see it's uploading.

On older versions of nodemcu you had to do some ninja thing before flashing:

• push reset (keep it pushed)
• push the flash button (keep it pushed)
• click on "upload" in the Arduino IDE (ninja skill or third hand required)
• release the reset button

I'm an idiot I realized I didn't have the right drivers downloaded on to my computer but thanks for the help any ways. I successfully uploaded the deauther on to the board.

closing this as resolved, thanks for reporting the solution!

this is my error and it's repeating. I think my drivers have no problem but i am stuck here. Can you please help me ?
