i have bought esp8266 and wired with a 3.3v ftdi .
i am using termit terminal program to communicate with esp
everything is okay when i send "AT" it responds ok but when i send " AT + <RST>" or "AT+ RST" it responds error and i do not know why.

is it a firmware problem?
or wiring problem with gpio0 and gpio2 because i left them free?

Try to wire those pins too and check if the circuit works then better.
