我正在使用支持BLE的硬件，并使用Android的Foreground Service与该硬件进行通信。前台服务负责处理BLE相关事件，并且在一段时间内按照要求运行良好，但是由于某种原因，如果前台服务被杀死或BLE连接断开，则应用会尝试再次重新连接到BLE，然后BLE回调开始从BluetoothGattCallback获取重复事件，即使硬件将单个事件发送到Bluetooth，但Android BluetoothGattCallback接收到相同的多个回调，这在我们的实现中导致很多错误。

作为参考，请按以下方式查看日志，

Following are methods and callbacks from my foreground service,
