[英]BLE functions in Ionic2
I'm new with Ionic 2 and I need to create an application using Bluetooth functions to connect with other devices like a sensor. 我是Ionic 2的新手,我需要使用蓝牙功能创建一个应用程序以与其他设备(例如传感器)连接。
Now I want to call functions when I click the button to scan, connect, disconnect devices but my function doesn't works. 现在,我想在单击按钮以扫描,连接,断开设备时调用函数,但是我的函数不起作用。
I'm using this plugin of cordova: https://github.com/don/cordova-plugin-ble-central#scan 我正在使用Cordova的这个插件: https : //github.com/don/cordova-plugin-ble-central#scan

export class SyncPage {
constructor(public navCtrl: NavController) {}
ionViewDidLoad() {
console.log('Hello SyncPage Page');
}
testing(){
console.log('Test button');

It is ' ble ' and not ' BLE '. 它是“ ble ”而不是“ BLE ”。 You may even wanna change the import statement. 您甚至可能想要更改导入语句。 I hope it works. 我希望它能起作用。
