Hello,
I've been controlling a brushless motor through its speed control using the Serial terminal between it and the computer using this code
#include <Servo.h>
Servo myservo;
int pos=50;
void setSpeed(int speed){
// speed is from 0 to 100 where 0 is off and 100 is maximum speed
//the following maps speed values of 0-100 to angles from 0-180,
// some speed controllers may need different values, see the ESC instructions
int angle = map(speed, 50, 110
, 50
, 180);
myservo.write(angle);
}
void setup()
{
Serial.begin(9600);
myservo.attach(6);
setSpeed(pos);
delay(1000);
}
void loop()
{
char recvChar;
if(Serial.available()){
recvChar=Serial.read();
if(recvChar == 'h'){
if(pos<74){
pos=pos+1;
}
else{
pos=74;
}
Serial.println(pos);
setSpeed(pos);
delay(1000);
}
if(recvChar == 'b'){
if(pos>55){
pos=pos-1;
Serial.println(pos);
setSpeed(pos);
delay(1000);
}
}
}
}
And it's working very good!, now I have bluetoothShield " http://www.seeedstudio.com/depot/bluetooth-shield-p-866.html " and i want to control the motor through the bluetooth terminal.So i wrote this code
#include <Servo.h>
#include <SoftwareSerial.h>
#define RxD 6
#define TxD 7
#define DEBUG_ENABLED 1
SoftwareSerial blueToothSerial(RxD,TxD);
Servo myservo;
int pos=50;
void setSpeed(int speed){
// speed is from 0 to 100 where 0 is off and 100 is maximum speed
//the following maps speed values of 0-100 to angles from 0-180,
// some speed controllers may need different values, see the ESC instructions
int angle = map(speed, 50, 110
, 50
, 180);
myservo.write(angle);
}
void setup()
{
Serial.begin(9600);
pinMode(RxD, INPUT);
pinMode(TxD, OUTPUT);
myservo.attach(6);
setSpeed(pos);
delay(1000);
setupBlueToothConnection();
}
void loop()
{
while(1){
char recvChar;
if(blueToothSerial.available()){//check if there's any data sent from the remote bluetooth shield
recvChar = blueToothSerial.read();
if(recvChar == 'h'){
if(pos<74){
pos=pos+1;
}
else{
pos=74;
}
setSpeed(pos);
delay(1000);
}
if(recvChar == 'b'){
if(pos>55){
pos=pos-1;
setSpeed(pos);
delay(1000);
}
}
}
}
}
void setupBlueToothConnection()
{
blueToothSerial.begin(38400); //Set BluetoothBee BaudRate to default baud rate 38400
blueToothSerial.print("\r\n+STWMOD=0\r\n"); //set the bluetooth work in slave mode
blueToothSerial.print("\r\n+STNA=SeeedBTSlave\r\n"); //set the bluetooth name as "SeeedBTSlave"
blueToothSerial.print("\r\n+STOAUT=1\r\n"); // Permit Paired device to connect me
blueToothSerial.print("\r\n+STAUTO=0\r\n"); // Auto-connection should be forbidden here
delay(2000); // This delay is required.
blueToothSerial.print("\r\n+INQ=1\r\n"); //make the slave bluetooth inquirable
//Serial.println("The slave bluetooth is inquirable!");
delay(2000); // This delay is required.
blueToothSerial.flush();
}
BUT IT'S NOT WORKING!, IT doesn't do anything to the motor although the same code will work if i used it with a Servo motor!
Please any help because I can't proceed in my project and i feel very LOST! 
Thanks in advance!
