如果设置了sendNextWhenLastSuccess=true，主动断开连接后还会一直发送 #519

如果我需要发送很大的数据，数据分包发送，这时候，我主动断开设备的连接，按我的理解，应该是不在发送数据的，但是由于在 BleManager.getInstance().write(mBleDevice, UUID_SERVICE, UUID_WRITE, buffer, true, true, 30, callback); 设置了sendNextWhenLastSuccess=true，导致在SplitWriter 走到发送失败 onWriteFailure回调方法中，mHandler一直在继续发送数据

 @Override
                            public void onWriteFailure(BleException exception) {
                                if (mCallback != null) {
                                    mCallback.onWriteFailure(new OtherException("exception occur while writing: " + exception.getDescription()));
                                }
                                if (mSendNextWhenLastSuccess) {
                                    Message message = mHandler.obtainMessage(BleMsg.MSG_SPLIT_WRITE_NEXT);
                                    mHandler.sendMessageDelayed(message, mIntervalBetweenTwoPackage);
                                }
                            }

我按照自己的需求，在发送失败后，加了个判断，如果当前为连接状态才让它继续发

@Override
                            public void onWriteFailure(BleException exception) {
                                if (mCallback != null) {
                                    mCallback.onWriteFailure(new OtherException("exception occur while writing: " + exception.getDescription()));
                                }
                                int connectState = BleManager.getInstance().getConnectState(mBleBluetooth.getDevice());
                                if (mSendNextWhenLastSuccess
                                        && connectState == BluetoothProfile.STATE_CONNECTED) {
                                    Message message = mHandler.obtainMessage(BleMsg.MSG_SPLIT_WRITE_NEXT);
                                    mHandler.sendMessageDelayed(message, mIntervalBetweenTwoPackage);
                                }
                            }
