Adafruit ESP8266 (ESP-12) Huzzah not responding to AT commands.

[BayBayMan]

My esp8266 Huzzah breakout board was recently reflashed using the esp flash tool, with the NONOS SDK v2.0.0. I figured this would allow the esp to respond when sent AT commands through the arduino serial monitor, but it did not.

I'm part of a group that is building something that requires a wifi connection that communicates with the Arduino MEGA. For right now, I just want to get the esp to respond to AT commands. I have tried using Putty and Realterm, but I don't know if I am using it correctly. I was following some instructions from a user on the arduino forums that stated just opening the serial monitor and sending AT+GMR should return the firmware version. We get no responses, though.

When we flashed the esp8266 Huzzah, it stated it was successfully flashed. We used a FTDI console cable to flash the esp8266 huzzah, by the way.
Below are the settings we have for the flash tool.


Below is what we get after it was flashed.

I just send AT commands from PC using a serial debug tool. It works fine..
Baudrate of AT firmware is 115200. And AT command ends with a new line (CR LF).
