Device not authorized to use BluetoothLE

See original GitHub issue

Hi, just upgraded to react-native-ble-plx from a different ble module. I’m getting an error when I run startDeviceScan on android 8.0.0, react-native 0.54.4:

Error: Device is not authorized to use BluetoothLE
    at new BleError (BleError.js:53)
    at parseBleError (BleError.js:68)
    at scanListener (BleManager.js:298)
    at RCTDeviceEventEmitter.emit (EventEmitter.js:181)
    at MessageQueue.__callFunction (MessageQueue.js:353)
    at MessageQueue.js:118
    at MessageQueue.__guardSafe (MessageQueue.js:316)
    at MessageQueue.callFunctionReturnFlushedQueue (MessageQueue.js:117)
    at t (RNDebuggerWorker.js:1)

This seems like it would be a permissions problem, but it isn’t.

AndroidManifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          ...
          xmlns:tools="http://schemas.android.com/tools">
          ...
          <uses-permission android:name="android.permission.BLUETOOTH" />
          <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
          <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
          <uses-feature android:name="android.hardware.bluetooth_le" android:required="true"/>
          <uses-sdk
                  android:minSdkVersion="18"
                  android:targetSdkVersion="23"/>
          ...

The bleManager reports that bluetooth is “PoweredOn” and I’ve verified this directly.

Whats going wrong here?

I checked the app install, and despite the fact that the AndroidManifest.xml requests the correct permissions (and a bunch of other permissions as well), Android’s App Info says “No Permissions Granted”.

I went to Settings > Apps and notifications > App permissions > Location Permissions and my app was turned off for some reason. Turning it on resolved the problem.

Looks like even if you ask for permissions in the manifest, Android might not grant them. Apparently the way you solve this is by using react-native’s PermissionsAndroid and asking in app to get location enabled. I’m closing this issue, but we might want to add something about this in the README.

You promised to update the README, imagine how we can make the world a better place by writing 1 line in readme to save hundreds if not thousands of hour for humanity 😃
