ESP8266 Community Forum

I'm new to the ESP8266 V3 and don't really understand it.
Armed with the tutorial on youtube I found out how to install the evil twin on this device, in the tutorial I was asked to enter the device serial number for the flashing process, but I didn't have it.

I've asked the seller of this ESP8266 but they won't give it away. Is there a way to find out?

Sorry, my English is not good

Thank you.

The serial number is the chip ID in your screen shot

That's the screenshot I took in the video tutorial, where the correct serial number is 3721590. I have also tried to input the chip ID but it can't.
