ESP8266 Community Forum

Before updating the firmware on a couple of my ESP8266's, I was able to use Putty to send AT commands and interrogate them, for example AT+GMR returned firmware version.
After updating firmware to 902, none of the AT command return any response using putty, however, the units are function perfectly in circuit... what am I missing?

[SOLVED] See post by ptamike below...

try with baud rate of 9600 (or 115200)

If I remember when I've upgraded my module, there was also a change regarding CR vs CRLF.

Baud rate is correct (don't forget it works in an application so I needed to alter the baud to 9600 in the code too), @martinayotte, I did suspect some sort of issue with LF/CR but couldn't find any reference to it... I'll search again... Many thanks guys...
