[Help]: scanning doesnt find my device #768

Closed salex996 closed 5 months ago

salex996 commented 5 months ago

Requirements

Have you checked this problem on the example app?

Yes

FlutterBluePlus Version

flutter_blue_plus: ^1.31.8

Flutter Version

3.16.7

What OS?

Android

OS Version

14

Bluetooth Module

Google Tensor G2

What is your problem?

I followed the example but I still don't have anything in return

The code I have is the following:

Future findDevices() async {

List devices = [];

var subscription = FlutterBluePlus.scanResults.listen((results) { if (results.isNotEmpty) { ScanResult r = results.last; // the most recently found device devices.add(r); print('${r.device.remoteId}: "${r.advertisementData.advName}" found!'); } }, onError: (e) => print(e), ); await FlutterBluePlus.startScan(timeout: const Duration(seconds: 20), continuousUpdates: true);

return devices;

Can you please help me? I do not understand why If I use the example of scanning that you have in the main page, I have nothing in devices

Thank you very much for your support

look at readme common problems please

Same here, nothing returned, I had to use bondedDevices and for scanning new devices I had to redirect the user to BL screen and do it over there.

these are common issues that FBP cannot fix.
