What is your problem?

Hello everyone, when connecting the device, after the scanner, it takes a long time or it is random for it to work. Or if I use Auto connect it never stays in the connected state, I have tried everything but it is still unstable, has this happened to anyone?

await device.connectAndUpdateStream(); It works randomly

await device.connect(autoConnect: true, mtu: null); It doesn't stay connected, if I add a delay sometimes yes.

Logs

No log.

FBP cannot control the connection quality. This is controlled by system bluetooth driver, wireless quality, etc.

without logs, I don't even know what you are talking about really.

you can look at the device.disconnectReason

smithFlutter commented 6 months ago

Thanks for your response, the problem is that it runs immediately and remains disconnected

await device.connect(autoConnect: true, mtu: null, timeout: Duration(seconds: 90));

The connection code is in Main.dart. Sometimes it works well and sometimes it doesn't, how can I send the log?

read the README about autoconnect....

this is explained in multiple places.

Thanks for the help, I will look for that README to be able to solve my problem, something so simple has been so complicated and delayed.

I have not been able to solve the problem, I read the readme but it does not help me much, I will evaluate changing the component, I have been doing this for a long time and it should be simple. Thanks for the help.
