Android BluetoothGatt - status 133 - register callback

Question

First of all I read SOLVED: GATT callback fails to register and took the steps suggested in that post to solve this issue with no success. The recommended fix in there if you ha

Answer 1

Try to use next workaround:

private static boolean gatt_status_133 = false;

final Handler handler = new Handler();

public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {

    if (newState == BluetoothProfile.STATE_CONNECTED) {
        mConnectionState = STATE_CONNECTED;
        Log.i(TAG, "Connected to GATT server.");
        // Attempts to discover services after successful connection.
        Log.i(TAG, "Attempting to start service discovery:" +
                mBluetoothGatt.discoverServices());

    } else if (newState == BluetoothProfile.STATE_DISCONNECTED) {
        if(status == 133)
        {
            gatt_status_133=true;
        }
        else{
            mConnectionState = STATE_DISCONNECTED;
            Log.i(TAG, "Disconnected from GATT server."); 
        }
    }
}


@RequiresApi(api = Build.VERSION_CODES.M)
public boolean connect(final String address) {
    if (mBluetoothAdapter == null || address == null) {
        Log.w(TAG, "BluetoothAdapter not initialized or unspecified address.");
        return false;
    }

    // Previously connected device.  Try to reconnect.
    if (mBluetoothDeviceAddress != null && address.equals(mBluetoothDeviceAddress)
            && mBluetoothGatt != null) {
        Log.d(TAG, "Trying to use an existing mBluetoothGatt for connection.");
        if (mBluetoothGatt.connect()) {
            mConnectionState = STATE_CONNECTING;
            return true;
        } else {
            return false;
        }
    }

    final BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(address);
    if (device == null) {
        Log.w(TAG, "Device not found.  Unable to connect.");
        return false;
    }

    mBluetoothGatt= device.connectGatt(this, false, mGattCallback, BluetoothDevice.TRANSPORT_LE);
    Log.d(TAG, "Trying to create a new connection.");
    mBluetoothDeviceAddress = address;
    mConnectionState = STATE_CONNECTING;

    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            if(gatt_status_133)
            {
                Log.d(TAG, "Catch issue");
                connect(address);
                gatt_status_133=false;
            }
        }
    }, 4000);

    return true;
}
