Can't send 9600 bits per second thru Serial via Bluetooth Dongle?

#include <ble_mini.h>
#include <Servo.h>

#define SERVO_PIN 7

Servo myservo;

void setup()
{
BLEMini_begin(57600);
myservo.attach(SERVO_PIN);
}

void loop()
{

// If data is ready
while ( BLEMini_available() == 3 )
{
// read out command and data
byte data0 = BLEMini_read();
byte data1 = BLEMini_read();
byte data2 = BLEMini_read();

if (data0 == 0x03) // Command is to control Servo pin
{
myservo.write(data1);
}
else if (data0 == 0x04) // Command is to reset
{
myservo.write(0);
}
}

}
