Touchscreen + Mouse + Bluetooth(RN-42) Absolute/Relative Position

Hi,
I searched A LOT on both this forum and the internet but I really cannot find an answer to my problem
I’m using the TouchScreen library to read finger position and a RN-42 (from sparkfun) to send these info to my tablet the problem is that the mouse is not moving in the “right” way. I managed to move to cursor to the top/bottom right/left position but as I said before everything is acting in a “weird” way (I can record a video if you want.
Here’s my script

#include <stdint.h>
#include <TouchScreen.h>
#include <SoftwareSerial.h>

SoftwareSerial rn42 = SoftwareSerial(4,5);  //RN-42 TX attached to Digital 4, RX attached to Digital 5
uint8_t buffer[7];

#define YP A2  // must be an analog pin, use "An" notation!
#define XM A1  // must be an analog pin, use "An" notation!
#define YM A3   // can be a digital pin
#define XP A0   // can be a digital pin

//TouchScreen ts = TouchScreen(XP, YP, XM, YM); //init TouchScreen port pins
TouchScreen ts = TouchScreen(YP, XP, YM, XM); //init TouchScreen port pins

void setup()
{
  Serial.begin(115200);          //  setup serial
  rn42.begin(115200);
}

void MoveMouse(int x, int y){
  buffer[0] = 0xFD;
  buffer[1] = 0x05;
  buffer[2] = 0x02;
  buffer[3] = 0x00; //Buttons
  buffer[4] = byte(x); //X-stop 
  buffer[5] = byte(y); //Y-stop
  buffer[6] = 0x00; //Wheel
  rn42.write(buffer, 7);
}

void loop()
{
  // a point object holds x y and z coordinates
  TSPoint p = ts.getPoint();
  
  // we have some minimum pressure we consider 'valid' pressure of 0 means no pressing!
  if(p.x < 180 || p.x > 190){//(ts.pressureThreshhold > 0) {//
    MoveMouse(-p.x, -p.y);
    Serial.print("X = "); Serial.print(p.x);
    Serial.print("\tY = "); Serial.print(p.y);
    Serial.println("");
  }

  delay(100);
}
void MoveMouse(int x, int y){
  buffer[0] = 0xFD;
  buffer[1] = 0x05;
  buffer[2] = 0x02;
  buffer[3] = 0x00; //Buttons
  buffer[4] = byte(x); //X-stop 
  buffer[5] = byte(y); //Y-stop
  buffer[6] = 0x00; //Wheel
  rn42.write(buffer, 7);
}

Why does the function accept ints, and then discard the high order byte?

the problem is that the mouse is not moving in the "right" way.

The code does something. You expect it to do something. Neither thing is clearly defined.

What is the bluetooth device connected to? What is receiving the mouse move information?

I found that function in a topic about the RN-42. You can take a look at the manual to see the accepted Raw Report.

The RN-42 is connected to my Nexus7. I think that the problem is that I do not know how to move the mouse using absolute position instead of relative (I thought about using it a digitizer but I cannot find Raw Report for digitizer).
