Same issue, any solutions ??

[iyashiyas]

solved the issue with adding permission from flutter also added android manifest.xml

var statusLocation = Permission.location;
var statusScan = Permission.bluetoothScan;
var statusConnect = Permission.bluetoothConnect;
if (Platform.isAndroid) {
if (await statusLocation.isDenied) {
await [
Permission.location,
].request();
}

    if (await statusLocation.isGranted &&
      await statusScan.isGranted &&
      await statusScan.isGranted) {
    commonPrint('all grnted');
    // do scan bluetooth device function
  }

@iyashiyas @ferns-it can you share your AndroidManifest and a more detailed code snippet? Specifically have you used permission_handler package?

@iyashiyas @ferns-it I was able to figure out. Thank you. However, it does not work with Android 12. Worked fine with Android 9.

Android 12 doesn't work initially. You'll have to follow this: https://stackoverflow.com/questions/70578601/android-12-ble-scan-does-not-find-any-devices

As a result, I had these in the Android manifest file:

  <uses-permission android:name="android.permission.BLUETOOTH" />
  <uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
  <uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
  <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

Then I request the following permissions at runtime:

await Permission.bluetoothConnect.request();
await Permission.bluetoothScan.request();
await Permission.locationWhenInUse.request();
