Android OTA服务 - END字节返回错误129

Question

我现在解决了之前的使用问题，但是当我正在编写结束字节时这样做：

   case "OTAEND":
                Log.d("OTAEND", "Called");
                handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        writeOtaControl((byte) 0x03);
                    }
                },500);
                break;

使用此方法：

  /**WRITES BYTE TO OTA CONTROL CHARACTERISTIC*****************************************/
    public boolean writeOtaControl(byte ctrl) {
        Log.d("writeOtaControl", "Called");

        if (bluetoothGatt.getService(ota_service)!=null){
            BluetoothGattCharacteristic charac = bluetoothGatt.getService(ota_service).getCharacteristic(ota_control);
            if (charac != null) {
                Log.d("Instance ID", "" + charac.getInstanceId());
                charac.setWriteType(BluetoothGattCharacteristic.WRITE_TYPE_DEFAULT);
                Log.d("charac_properties", "" + charac.getProperties());
                byte[] control = new byte[1];
                control[0] = ctrl;
                charac.setValue(control);
                bluetoothGatt.writeCharacteristic(charac);
                return true;
            } else {
                Log.d("characteristic", "null");
            }
        } else {
            Log.d("service", "null");
        }
        return false;
    }

在这个回调中，我获得了错误代码 129 的状态，这在BLE的文档中都没有。

  @Override //CALLBACK ON CHARACTERISTIC WRITE (PROPERTY: WHITE)
        public void onCharacteristicWrite(BluetoothGatt gatt, BluetoothGattCharacteristic characteristic, int status) {


            if (status != 0){ // Error Handling
                Log.d("onCharWrite", "status: " + Integer.toHexString(status));
                final int error = status;
                runOnUiThread(new Runnable() { //Display error on Toast
                      @Override
                      public void run() {
                          Toast.makeText(getBaseContext(), charErrorHandling(error), Toast.LENGTH_LONG).show();
                      }
                });

这是我的HCl日志：
