Woohoo - its working 
bigengineer - your set control escape line that you gave didn't work. I changed it to:
Serial.println("SET CONTROL ESCAPE 43 00 0");
and the thing burst into life.
Sending the command INQUIRY 5 NAME returned the following:
READY.
INQUIRY 5
INQUIRY 00:0b:0d:4d:fb:f8 020104
INQUIRY 00:10:60:10:76:06 020340
INQUIRY 00:05:c9:fa:71:16 520204
INQUIRY 00:1a:75:f4:44:aaNAME 00:0b:0d:4d:fb:f8 "MWLAPTOP"
NAME 00:10:60:10:76:06 "BTAP-7606"
NAME 00:05:c9:fa:71:16 "banana LG"
NAME 00:1a:75:f4:44:aa "K550i"
NAME 00:18:13:08:c9:98 "What? "
it can be seen that there are some transmission errors somewhere in the data transfer. I wonder if the AVR can keep up with the serial data from the WT-11 when it is writing to the EEProm.
The code I used was:
#include <EEPROM.h>
int ledPin = 13; // LED connected to digital pin 13
int resetPin = 7; // BT module uses pin 7 for reset
char inByte = 0; // incoming serial byte
int infoSize = 0 ;
void setup() // run once, when the sketch starts
{
pinMode(ledPin, OUTPUT); // sets the digital pin as output
pinMode(resetPin, OUTPUT);
Serial.begin(115200); // start serial at 115200 kbs
Serial.println("SET CONTROL ESCAPE 43 00 0");
}
void loop()
{
// if we get a valid byte, read analog ins:
if (Serial.available() > 0) {
inByte = getbyte(); // get incoming byte
if (inByte == '&' ) { // look for a &
Serial.print("Got an & ");
infoSize = getInfo();
Serial.println("Done");
}
else if (inByte == '@' ) { // look for a 0
digitalWrite(ledPin, LOW); // set led LOW
Serial.print("Get string: ");
for(int i=0;i<infoSize;i++)
{
Serial.print(EEPROM.read(i));
}
Serial.println();
Serial.print("Cleared string size: ");
Serial.println(infoSize);
}
}
}
int getInfo()
{
int j=0;
digitalWrite(ledPin, HIGH); // set led HIGH
delay(2000);
Serial.print("+++");
delay(2000);
Serial.println("INQUIRY 5 NAME");
for (int i=0; i <= 10; i++){
delay(1000);
while (Serial.available() > 0 && j <512) {
inByte = getbyte(); // get incoming byte
EEPROM.write(j, inByte);
j++;
}
delay(1000);
}
delay(2000);
Serial.print("+++");
delay(2000);
digitalWrite(ledPin, LOW); // set led low
return j;
}
char getbyte()
{
while (Serial.available() == 0) { //look for aviable data
// do nothing, wait for incoming data
}
return Serial.read(); //return data if aviable
}
There is still some work to do - finding the cause of the transmission errors and I guess some external SRAM is required as it looks like the string data back from the WT-11 could easily exceed the EEProm and ram in the AVR.
