嗨我正在閱讀從BLE設備的心率和顯示在應用程序。但BLE BluetoothGattExecutor在我的應用程序中連續讀取和寫入呼叫，如果我在後臺連續運行，CPU使用率很高。BLE BluetoothGattExecutor讀寫連續不斷，CPU使用率高？

什麼是BluetoothGattExecutor？您的代碼是基於[此示例項目]（http://www.java2s.com/Open-Source/Android_Free_Code/Sensor/heart/com_sample_hrvBluetoothGattExecutor_java.htm）？ –
@KevinKrumwiede是這個代碼只有 –
@KevinKrumwiede如果我使用相同的代碼意味着心率不顯示。 –
