Hey folks, glad to join esp8266 community. I have a problem with getting AT commands to respond over USB-TTL converter. I've flashed AT firmware from esp-at repo(I configured and built it to available RXD0/TXD0 pins). Flashed successfully, but it would never respond to any AT commands using any serial console. For ex. Arduino serial monitor can see the reset events, and it boots returning

Code: Select allets Jan 8 2013,rst cause:1, boot mode:(3,6)

, which from what I found seems to be successful boot. What am I missing?

AT commands need LF as the line terminator. Make sure your console is using that or use CTRL-A which will send LF.

Yeah I had that enabled. As I mentioned - I have it properly working using nodemcu board(which also uses esp 12e), but not with directly connected esp 12e
