I'm new to ESP8266. I used ESP-201 before and I had no problems with it. Now, I designed my own board, i.e. I used ESP8266 chip directly. So, I should program my esp to work. I used 32Mbit flash, downloaded the latest version of NonOs SDV v2.0 using standard ESP8266 flash download tool. However, my ESP does not work(I tried much) . when I power up the board, the "ready" received by the PC but it doesn't answer to the AT commands. for example when I send "AT" it responds "AT" and so for the other commands.
Can anyone guide me about it?
thanks
