BLE Permission not working on 0.63.2 with Android 10

Hello there,

My project was on React Native 0.63.2 version and when I tried to scan ble devices couldn’t see any of them. Even I asking permission and allow the location. It happens only Android 10 devices. When I check the error callback it says: [BleError: Device is not authorized to use BluetoothLE]
This error not happens on 0.62.2

Interesting things are:

• When I ask permission on Android 10, it’s not ask “Allow Always”, only “Allow While Using” and “Deny”
• When I go to Settings => Apps => <My App> => Permissions => Location section and I select “Deny” and “Allow While Using” again, the error disappears and app can search devices properly.

Buggy versions:

    "react": "16.13.1",
    "react-native": "0.63.2",
    "react-native-ble-plx": "^2.0.1"

Working versions:

    "react": "16.11.0",
    "react-native": "0.62.2",
    "react-native-ble-plx": "^2.0.1"

AndroidManifest.xml permissions

  <uses-permission android:name="android.permission.INTERNET" />
  <uses-permission android:name="android.permission.BLUETOOTH"/>
  <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

It may not happens because of this package, maybe React Native itself but I found it on this package.

Hi,

I had the same issue when I updated my targetSdkVersion from 28 to 29.

Replacing the android permission ACCESS_COARSE_LOCATION with ACCESS_FINE_LOCATION in my AndroidManifest.xml and in my app’s code for manually asking the user with PermissionAndroid fixed it for me.

Recap of what’s working for me : build.gradle :

buildToolsVersion = "29.0.2" 
minSdkVersion = 18 
compileSdkVersion = 29 
targetSdkVersion = 29 

AndroidManifest.xml :

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<uses-permission-sdk-23 android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-feature android:name="android.hardware.bluetooth_le" android:required="true"/>
<uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>

in my app’s code :

const granted = await PermissionsAndroid.request(
	PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION,
	{
		title: 'Permission Localisation Bluetooth',
		message: 'Requirement for Bluetooth'
		buttonNeutral: 'Later',
		buttonNegative: 'Cancel',
		buttonPositive: 'OK',
	}
);

Hope this helps.

I struggled with this issue for about 6 hours, nothing worked. Then I restarted my phone and it worked immediately.
