ESP8266 Community Forum

Hello there!sorry if i m posting in a wrong session..i just bought two esp8266 modules and this https://www.sparkfun.com/products/9873 ftdi module.i did the wiring like this https://www.youtube.com/watch?v=9QZkCQSHnko .the problem is that when i try to upload some code,it says error epcomm_open failed error..tried a lot of things with no luck..any ideas?

EDIT:i ve also tried this tutorial http://rancidbacon.com/files/kiwicon8/E ... _1.0.4.pdf
and surprisingly,when i hook up the esp (open serial monitor) i get this: ready.
but when i try to send AT or AT+RST nothing happens.it just writes the command i ve send in the serial monitor.
what could it be??

Are you sending both CR+LF after the AT command, not only CR ?

you mean if i have chosen on the bottom of the window :both nl and cr?if that,i tried even this or the Carriage return one.

Some terminal program at buggy even with this kind of option, they are sending LFCR instead of CRLF which confused the AT parser. Try it manually on the keyboard <enter>+<ctrl-J>.
