Unable simply Scan from a Clean-started project with Ionic-Capacitor

Open user1337 opened this issue 4 years ago • 2 comments

Hi there!

It there anyone who is capable to do a Ionic project with Capacitor that is capable of doing a Scan and getting "scanResult" ? I also got a success from "scanStarted".

I started by following the steps for Capacitor installation from : https://ionicframework.com/docs/native/bluetooth-le

Otherwise, I also start a Ionic project with "Cordova" and the Scan is working and I get scan results with some devices.

What I also did was :

  • Before do "startScan" I also ask for permissions before : requestPermission() requestLocation()

  • Add bluetooth permissions to "src\main\AndroidManifest.xml" : android.permission.BLUETOOTH android.permission.BLUETOOTH_ADMIN android.permission.ACCESS_FINE_LOCATION android.permission.ACCESS_COARSE_LOCATION android.permission.ACCESS_BACKGROUND_LOCATION android.hardware.bluetooth_le" android:required="true"

  • Add permissions to "node_modules\cordova-plugin-bluetoothle\plugin.xml" : android.permission.BLUETOOTH android.permission.BLUETOOTH_ADMIN android.permission.ACCESS_FINE_LOCATION android.permission.ACCESS_COARSE_LOCATION android.permission.ACCESS_BACKGROUND_LOCATION android.hardware.bluetooth_le" android:required="true"

  • Set the SdkVersion of "variables.gradle" : minSdkVersion = 23 compileSdkVersion = 29 targetSdkVersion = 29

Thanks, Huy

I tried the same and received this error in the console. Is that what you received?

Are you calling requestPermission() before hand?
