Example app requires Android Location Permissions but does not request for it

[movaid7]

Within the Provisioning and Control tabs, the example app fails to find modules if Location Permissions are not granted. However, the app never asks the user for device location access. Modules are found once the app is manually granted Location Permissions.

After manually adding location permissions

Hello @movaid7 ! Indeed, from android 6 to 11, location permission is needed along with the ble one. We didn't put the permission requests so the app is as simple as possible, but you probably want to import permission_handler pkg to handle it.

With the release of Android 12, the logic should be :

• android 6 to 11 -- request Bluetooth AND location permissions
• android 12 and beyond -- request Bluetooth permissions (⚠️not the same as lower versions ble permission)

I will give you a snippet to handle it properly 👍 We may also add it to the example app or in the readme for better understanding

Something like this :

  Future<void> _checkAndAskPermissions() async {
    final androidInfo = await DeviceInfoPlugin().androidInfo;
    if (androidInfo.version.sdkInt! < 31) {
      // location
      final locationPermission = await Geolocator.checkPermission();
      if (locationPermission != LocationPermission.always &&
          locationPermission != LocationPermission.whileInUse) {
        _log('location permission is needed');
        await Geolocator.requestPermission();
      }
      // bluetooth
      final bluetoothPermission = await Permission.bluetooth.status;
      if (bluetoothPermission == PermissionStatus.granted) {
        _log('all good permissions');
      } else {
        _log('BLE permission is needed');
        await Permission.bluetooth.request();
      }
    } else {
      // bluetooth for Android 12 and up
      final bluetoothScan = await Permission.bluetoothScan.status;
      final bluetoothConnect = await Permission.bluetoothConnect.status;
      if (bluetoothScan == PermissionStatus.granted &&
          bluetoothConnect == PermissionStatus.granted) {
        _log('all good permissions');
      } else {
        _log('some BLE permissions are needed');
        await Permission.bluetoothScan.request();
        await Permission.bluetoothConnect.request();
      }
    }
  }

There are 3 pkgs involved 😅 but you may not need geolocator 🤔

That should do the trick 👌
