How can I change the MTU or Packet Size for Bluetooth in Android?! It is not possible in using Android's API, right? I believe I should change the native codes. How can I change it? And is it also possible to change the transmission rate, or it is hardware dependent? Thanks

Yes, You are right - it is not possible in Android API. You can only get MTU value for an interface with networkInterface.getMTU() method.
Based on sources for the NetworkInterface class
public int getMTU() throws SocketException {
return readIntFile("/sys/class/net/" + name + "/mtu");
}
You probably can change MTU value (for rooted devices) - You need to write new int MTU value to "/sys/class/net/" + networkInterface.getName() + "/mtu" file.
But I'm not sure if it is reliable solution for You.
