Was anyone able to use bluetooth in their Compose desktop app (or even a CLI kotlin/java app)? I understand this is not a Compose related question and out of scope of Compose Desktop, but im running in loops trying to find how to run java bluetooth apis on modern hardware (Mac M1).

Not sure if it's relevant, but some of the emulated Bluetooth options on macs struggle because of new security restrictions. Could it be that? If so, I think you can self sign for Dev. But need apple to grant for distribution.

my issue is that I am not able to run any bluetooth related code on my mac. I have found bluecove which seems to be the implementation of the bluetooth interface for java, but the official releases are not supported for 64bit architecture. I tried running my app using 32bit (JVM option -d32) but I am getting this error when I use any bluetooth API:

Yeah, looks quite different.

actually that was a lie. Just realized that -d32 is not supported by latest java versions. will try downgrading
