Hi, I get following error, may somebody advice me how to solve this.

Error in ./TabsPage class TabsPage - caused by: No provider for BluetoothSerial!

StackTrace:

Error: DI Error

My Code:

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 {

constructor(public navCtrl: NavController, private bluetoothSerial: BluetoothSerial) {
//console.log(bluetoothSerial.isEnabled());
//console.log(bluetoothSerial.list());
}
}

Did you first install the Bluetooth Serial native component?

$ ionic plugin add cordova-plugin-bluetooth-serial
$ npm install --save @ionic-native/bluetooth-serial

Yes, I hav installed the native component. However, npm prints warnings at installing the serial comp., I dont know if this causes the problem.

npm install --save @ionic-native/bluetooth-serial
npm WARN optional Skipping failed optional dependency /chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.1.1

This is caused by the fact that you are using ionic-native 3 syntax on 2.8. Either upgrade to 3.1.0 or change your import to be from ‘ionic-native’.

5

Ok, how do I upgrade to ionic-native 3? I changed the ionic-nativ version number in package.json, but npm prints out that the most recent valid target version is 2.9.

see:

npm ERR! notarget No compatible version found: ionic-native@3.1.0
npm ERR! notarget Valid install targets:
npm ERR! notarget 2.9.0, 2.8.1, 2.8.0, 2.7.0, 2.6.0, …

PS.:

Even if I change the import to “ionic-nativ”, I get the error.
“import {BluetoothSerial} from “ionic-native”;”

Ok, I removed ionic/native 2.8.1 and installed 3.1.1. Still same issue!

Have you completely erased node_modules, cleared the npm cache, and run npm install again?

8

Ok, Bros! I solved the problem.

I didn’t declared the bluetooth provider in my app modules.

thx and best regards!
