I connected RX a TX to lines FTDI chip , Reset and CH_PD pulled to 3.3v and I am using LM317 as USB 5V to 3.3V converter. So I started terminal session and here the results.

So esp8266 searching AP well but module does not want to connect to it. I tried two esp8266 and two Access Points and in both variants result is "FAILED". I even flashed v0.922 firmware in one of the module but result left the same. Can anyone give me an advise what I am doing wrong?

- Thu Nov 27, 2014 2:50 pm #3407 5 minutes ago find my mistake with CWMODE but i tested AT+CWMODE=3 and AT+CWMODE=2 but AT+CWJAP="HomeNet","*************" returning FAIL. But when i create AP by ESP8266 everything works fine and my notebook connecting to ESP8266. What a hell is wrong with AT+CWJAP=

- Fri Nov 28, 2014 4:46 am #3450 I've seen this issue with CWJAP failing using my own FW built on SDK 0.9.3. Usually it helps if I restart the device a couple of times.

Apparently a new release of the AT code by Espressif is due today(?) so hopefully it solves a few of the bugs as well.
