The problem is: I want to establish communication between my desktop and my android smart device.

I’m trying a simple step but I get “device not found” as return

this is where I base my coding: [https://ionicframework.com/docs/native/serial/](https://ionicframework.com/docs/native/serial/)

this is the code:

> import { Component, OnInit } from ‘@angular/core’; import { NavController } from ‘ionic-angular’; import {Serial} from ‘@ionic-native/serial’;
> 
> @Component({ selector: ‘page-home’, templateUrl: ‘home.html’ }) export class HomePage implements OnInit { public status:string;  
> constructor(public navCtrl: NavController, public serial:Serial) {
> 
> }
> 
> ngOnInit(){  
> this.serial.requestPermission({vid:“04e8”,pid:“6860”,driver:“FtdiSerialDriver”})//I already have tried to omit the request options but got the same error .then(()=\>{ this.status = “Permission requested”; //this would be the successfully result }).catch(error=\>{ this.status = error.toString(); // it’s returning “device not found” }); } }

there are few content about this feature on web.
