[chipweinberger]

never seen this issue before.

it's normal for it to be unavailable breifly.

[karansingla007]

@chipweinberger how can i solve this issue. I couldn't able to scan device.

[chipweinberger]

perhaps you need to call some other FBP method to get bluetooth to initialize?

[karansingla007]

Which method, would you like to suggest?

[chipweinberger]

nevermind, i'm wrong. setLogLevel is good enough.

this seems like a macOS issue, not FBP issue

try restarting computer

[karansingla007]

i am already doing this.

FlutterBluePlus.setLogLevel(LogLevel.verbose, color: true);

[chipweinberger]

try restarting computer

youre on macOS 14, this is a new version of macOS and it will have bugs

[karansingla007]

Just did, Still the problem is same.

[chipweinberger]

make sure you've added permissions. see readme

[maham]

Our current workaround is to make sure to listen to FlutterBluePlus.adapterState before doing other calls. Not sure if this works for other cases.

[chipweinberger]

@maham the problem is that FlutterBluePlus.adapterState gets stuck on unavailable

@karansingla007 any updates?

[thiruarasu16]

We need to give permission for that bluetooth access, for that open macos project in xcode-> Runners->Targets->Runner->Signing and capabilities ->App sandbox ->hardware -> enable the bluetooth(tick the check box).

Hope above steps will help you in resolving this issue.

Thanks @thiruarasu16 , I've updated the README & Common Problems.
