我是Ionic 2的新手,我需要使用蓝牙功能创建一个应用程序来连接传感器等其他设备。
现在我想在单击按钮扫描,连接,断开设备时调用函数,但我的功能不起作用。
我正在使用这个cordova插件: https://github.com/don/cordova-plugin-ble-central#scan
.ts文件
import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { BLE } from 'ionic-native';
@Component({
selector: 'page-sync',
templateUrl: 'sync.html'
})
export class SyncPage {
constructor(public navCtrl: NavController) {}
ionViewDidLoad() {
console.log('Hello SyncPage Page');
}
testing(){
console.log('Test button');
}
BLE.scan([], 5, function(device) {
console.log(JSON.stringify(device));
}, failure);
BLE.startScan([], function(device) {
console.log(JSON.stringify(device));
}, failure);
}
.html文件
<ion-header>
<ion-navbar>
<button ion-button menuToggle>
<ion-icon name="menu"></ion-icon>
</button>
<ion-title>Sync</ion-title>
</ion-navbar>
</ion-header>
<ion-content padding>
<ion-buttons end>
<button ion-button (click)="testing()"><ion-icon name="add"></ion-icon>Test</button>
</ion-buttons>
<ion-buttons end>
<button ion-button (click)="scan()"><ion-icon name="add"></ion-icon>Scan</button>
</ion-buttons>
<ion-buttons end>
<button ion-button (click)="startScan()"><ion-icon name="add"></ion-icon>Startscan</button>
</ion-buttons>
</ion-content>
答案 0 :(得分:0)
' ble '而不是' BLE '。您甚至可能想要更改import语句。我希望它有效。
