i try to connect bluetooth via Bluetooth Serial plugin so i write these codes :
import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { BluetoothSerial } from '@ionic-native/bluetooth-serial';
@Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
device: Array<any>;
isconnected: string;
scanning:string;
constructor(public navCtrl: NavController,public bls:BluetoothSerial) {
this.device = [];
this.scanning = "no scan";
}
scan(){ this.scanning = "scan";
let that = this;
this.bls.list().then(function(d){
that.device = d;
that.scanning ="success";
},function(e){
that.scanning = "error";
});
}
checkConnect() {
let that = this;
this.bls.isEnabled().then(function(){
that.isconnected = "Enable";
},function(){
that.isconnected = "Disable"
