If you tried my exact instructions (open a serial connection @74880 baud and power cycle or reset your ESP) and you get above result in your terminal, something is definitely wrong. :roll:

Are you sure that nothing other than your USB -> serial converter, like for instance a LED, is connected to pins 2 (TX/GPIO1) and 7 (RX/GPIO3)?

Hi

I solved my problem and it's very easy :)

My C# App used this code [Before] :
Code: Select allserialPort1.Write(code + "\t\n");


But it should be [After] :
Code: Select allserialPort1.Write(code + "\r\n");


Thanks to everyone. :)

You would have known what your problem was if you had bothered to try out your commands with terminal program like Putty.

You have just wasted yours and others time by not being clear that you were using a C# program that you wrote.
