如何在IONIC 2中注册BLE状态通知 [英] How to register for BLE state notification in IONIC 2

问题描述

如在ILE 2的BLE的git中所提到的，我们可以注册BLE启用或禁用状态： https://github.com/don/cordova-plugin-ble-central#startstatenotifications 。但它给了我错误属性 startStateNotification 在BLE类型上不存在。我的代码是：

As mentioned in git of BLE for IONIC 2 we can register for BLE enable or disable state : https://github.com/don/cordova-plugin-ble-central#startstatenotifications . But It gives me error Property startStateNotification does not exist on type of BLE. My code is :

ble.startStateNotifications(
function(state) {
    console.log("Bluetooth is " + state);
});

我在这里缺少什么。我想要成功并且还要回避两个回调。请提供解决方案..

What I am missing here.I want success and failer both callbacks as well. Please provide solution..

推荐答案

您正在通过

从离子本地导入{ble}是吗？

import {ble} from ionic-native is it?

如果你看一下离子文件-native> dist> plugins> ble.js，提供了一个命令列表。检查是否有名为 startStateNotifications 的命令。

If you take a look at the files in ionic-native>dist>plugins>ble.js, there are a list of commands provided. Check if there is a command called startStateNotifications.

属性startStateNotification不存在于BLE的类型

Property startStateNotification does not exist on type of BLE

这很可能意味着ble没有这个功能。

This would most likely mean ble does not have this function.

您必须检查 ionic-native 是否使用最新版本的 cordova-plugin-ble-central 。

You have to check if ionic-native is using the latest version of cordova-plugin-ble-central.

更新

您可以通过在命令提示符中运行此命令来导入插件，而不是通过ionic-native导入：

Instead of importing through ionic-native, you can import the plugin by running this command in command prompt:

cordova插件添加cordova-plugin-ble -central

之后，您将使用它作为插件。所以只需调用 ble.startStateNotification（）您不需要在ionic-native 中包含 import {ble}。

Afterwards, you will use this as a plugin. So just call ble.startStateNotification() You will not need to include import {ble} from ionic-native already.

我更喜欢直接从主作者导入 cordova-plugin-ble-central 而不是通过 ionic-native 调用 cordova-plugin-ble-central 。如果插件有任何更新，您可以立即更新。否则，你将不得不等待 ionic-native

I prefer directly importing cordova-plugin-ble-central from the main author instead of going through ionic-native to call cordova-plugin-ble-central. In the event of any updates from the plugin, you can update immediately. Else, you will have to wait on ionic-native
