[Bug]: Failed assertion: line 90 pos 12: '(mtu == null) || !autoConnect': mtu and auto connect are incompatible

[doguhan2222]

Requirements

• [X] I've looked at the README 'Common Problems' section

Have you checked this problem on the example app?

Yes

FlutterBluePlus Version

flutter_blue_plus: ^1.30.6

Flutter Version

3.10.6

What OS?

Android

OS Version

13

Bluetooth Module

Esp32

What is your problem?

I have always used the same code and the same ESP32 device in 4 different projects for 4 different devices. They all have the same version of blue_plus. But in the last application I made, I cannot connect to the device when autoconnect = true. It gives this error. If I set autoconnect = false, I can connect to the device successfully.

This is my code for connecting to the device:

await BaglanilanBluetoothCihaz.BagliBluetoothDevice!.connect(
  autoConnect: true,
  timeout: const Duration(seconds: 15),
);

This is happening to me on iOS even when setting mtu to null

The same problem still persists. He said and left without any explanation. He was really zero helpful in terms of help.

Does the same problem persist in release mode? Have you tried it ?. Sometimes the problem disappears on its own in release mode.

[samnbd]

@doguhan2222 thank you very much, the issue as you suggested is gone when running the app in release mode on iOS and it also resolved this issue too
