Profile define all communication functions to a BLE device, you can assume it is a higher level of abstraction, it has one or more service, which expose the sensor data on a GATT server. Profile定义了BLE设备的所有通信功能，您可以假设它是一个更高级别的抽象，它有一个或多个服务，它在GATT服务器上公开传感器数据。 eg Heart rate, temperature or Cycle speed. 例如心率，温度或循环速度。 In simple Profile has Services, and Service has Characteristics, Characteristic descriptor. 在简单的Profile中有服务，而Service有特征，特征描述符。
