I get the following error message in WiFi access point mode:
ERROR
Device Not Reply
I can see the blue LED on my ESP8266 board flash when I attempt to connect my iPhone.
For some reason my ESP8266 is set to 115200 baud. So that's the only change I made to the code.
I re-flashed my ESP8266 to get the most recent code build as well.
Whats wrong?
And do you have any working examples of the ESP8266?
Thanks,
Charlie
...and here's my code...very simple...

I suggest that the board where it is connected can not handle the 115k2 speed at sotware serial RX2 / TX3
You have to connect it to RX / TX 0 and1 port , or change speed lower (9600) , but in that case you have to flash the ESP8266
See on topics how to set the ESP8266 to lower speed, and ofcourse yopu have to change your IDE code to the right pins and speed.
// PS: this will shoud when ESP8266 is set to 9600

Ok I will try one of your suggestions. I can see the decoded messages at 115200 baud on my Rigol oscilloscope in ASCII serial decode mode so at least part of the data is correct at 115200 baud using software serial. It could be however that something is being dropped from the message sequence.
OK works as access point in "hard serial" configuration. So "soft serial" didn't work at 115200 baud even though I saw some traffic on the serial line something was being missed using soft serial at 115200 baud. I suspect characters were dropped.
Now I'm trying to get ethernet access version to work with "hard serial"...no joy so far.
