Object(...) is not a function

[sergiocarral1]

Hi,

Sorry if my question doesn't make sense I new with angular and ionic
I tried the Scan example and when I launch the ionic serve it returns this error:

PairPage.html:31 ERROR TypeError: Object(...) is not a function
at BLE.scan (index.js:28)
at PairPage.webpackJsonp.73.PairPage.scan (pair.ts:79)
at Object.eval [as handleEvent] (PairPage.html:31)
at handleEvent (core.js:13589)
at callWithDebugContext (core.js:15098)
at Object.debugHandleEvent [as handleEvent] (core.js:14685)
at dispatchEvent (core.js:10004)
at core.js:10629
at HTMLButtonElement. (platform-browser.js:2628)
at t.invokeTask (polyfills.js:3)

Are we taking device and error as function when they are objects?

The only thing that is different is the import:
import { BLE } from '@ionic-native/ble/ngx';

@sergiocarral1 I am facing the exact issue. Did you get it resolved? Please help me. If you have used another library, please suggest.
Thanks in advance.

Hi All. I was looking at the very same issue. I found that by rebiulding my project and specifiying cordova in the ionic start command:

$ ionic start myApp blank --cordova

the error went away. I'm working in Ionic 4, so some other elements of this utorial will not be the same though. For instance, you'll need to change the imports to :

import { BLE } from '@ionic-native/ble/ngx';

hope this helps you.
