I made an Android app that connected and readed input fine with Wii balance board, based on Fitscales code. My app worked like a charm with SDK 15 & 16 until Android 4.4 (KitKat), when Android stopped the Wii support. Wii support is now re-enabled, starting with Android 5.1.1. I have also implemented the new permission scheme for obtaining Bluetooth connectivity permissions (inlcuded ACCESS_COARSE_LOCATION)
My problem is that I can't read Wii balance board input anymore.
I can discover, create socket and when connecting to socket I receive the message: read failed, socket might closed or timeout, read ret: -1
Answer that helped me so far and not working anymore:
Some code:
private BluetoothSocket createBluetoothSocket(
int type, int fd, boolean auth, boolean encrypt, String address, int port){
try {
Constructor<BluetoothSocket> constructor = BluetoothSocket.class.getDeclaredConstructor(
int.class, int.class,boolean.class,boolean.class,String.class, int.class);
constructor.setAccessible(true);
BluetoothSocket clientSocket = constructor.newInstance(type,fd,auth,encrypt,address,port);
return clientSocket;
} catch (Exception e) {
Log.v(TAG,"createBluetoothSocket failed: "+errorMsg(e));
return null;
}
}
private connectWii(String MAC) {
try {
// MAC is the MAC address of Wiiboard
int TYPE_L2CAP=3;
sk = createBluetoothSocket(TYPE_L2CAP, -1, false,false, MAC, 0x13);
// this fires read failed, socket might closed or timeout, read ret: -1
sk.connect();
} catch (Exception e) {
Log.v(TAG,"Failed : "+errorMsg(e));
}
}
Thank for your help in advance.
