能否实现蓝牙读取数据蓝牙设备数据功能

ebei222

请问  wex5能否能否实现蓝牙读取数据蓝牙设备数据功能，
我看了下cordova-plugin-ble-central插件的read方法，请问device_id, service_uuid, characteristic_uuid这几个uuid怎么获取。read方法的说明如下：


ble.read(device_id, service_uuid, characteristic_uuid, success, failure);

### Description

Function `read` reads the value of the characteristic.

Raw data is passed from native code to the callback as an [ArrayBuffer](#typed-arrays).

### Parameters

- __device_id__: UUID or MAC address of the peripheral
- __service_uuid__: UUID of the BLE service
- __characteristic_uuid__: UUID of the BLE characteristic
- __success__: Success callback function that is invoked when the connection is successful. [optional]
- __failure__: Error callback function, invoked when error occurs. [optional]

平台是提供了一个 有关蓝牙的插件，但是读取数据的能力应该不具备
