I was finally able to the the esp8266 updated to ESP code 0018000902. With that done my Arduino can now talk to the esp8266 at 9600 baud.
Below is some sample code that I am running just to do a rest, get rom release and then list access points. The key piece was to make sure you had the CR/LF added. at the end of the commands. You can also do a println if you like by add just the \r to the print statement. The TX and RX from the arduino are connect to RX/TX on the ESP8266. I also use a FTDI serial port and only connected the RX pin from the TX on the ESP8266 to monitor what was coming back from the wifi module.
#include <SoftwareSerial.h>
SoftwareSerial esp(7,8); //ESP firmware has to be 0018000902 so the baudrate can be set to 9600
void setup()
{
esp.begin(9600);
}
void loop()
{
esp.print("AT\r\n");
delay(500);
esp.print("AT+GMR\r\n");
delay(500);
esp.print("AT+RST\r\n");
delay(5000);
esp.print("AT+CWLAP\r\n");
delay(5000);
}
