* will received messages based on the length provided, this is useful in transfering binary data
* if we received this message (byte array) :
* {0x55, 0x55, 0, 3, 'a', 'b', 'c', 0x55, 0x55, 0, 9, 'i', ' ', 'a', 'm', ' ', 't', 'o', 'n', 'y'}
* then its parsed as 2 messages : "abc" and "i am tony"
* the first 2 bytes are the length data writted on 2 bytes
* byte[0] is the MSB
* byte[1] is the LSB
*
* on the unity side, you dont have to add the message length implementation.
*
* if you call bluetoothHelper.SendData("HELLO");
* this API will send automatically :
* 0x55 0x55 0x00 0x05 0x68 0x65 0x6C 0x6C 0x6F

* preamble Length Data
*
*
* when sending data from the arduino to the bluetooth, there's no preamble added.
* this preamble is used to that you receive valid data if you connect to your arduino and its already send data.
* so you will not receive
* on the arduino side you can decode the message by this code snippet:
* char * data;
* char _length[2];
* int length;
*
* if(Serial.avalaible() >2 )
* {
* _length[0] = Serial.read();
* _length[1] = Serial.read();
* length = (_length[0] << 8) & 0xFF00 | _length[1] & 0xFF00;
*
* data = new char[length];
* int i=0;
* while(i<length)
* {
* if(Serial.available() == 0)
* continue;
* data[i++] = Serial.read();
* }
*
*
* ...process received data...

*
* delete [] data; <--dont forget to clear the dynamic allocation!!!
