hallo@fritz122Ich habe das gleiche Problem, ich habe mich gefragt, ob Sie teilen könnten, wie Sie es gemacht haben. Rn Ich habe das Bluetooth, das anzeigt, dass es eingeschaltet ist, aber es funktioniert nicht, wenn ich zu den Einstellungen gehe. Wifi funktioniert einwandfrei, ich habe nur Probleme mit dem Bluetooth-Teil davon.

Ich habe einfach das Port Limit auf "false" nicht auf "true" gesetzt und dann ging auf einmal BT

Hi. Can you please tell me where I have to set port limit to "False" ? In which file? Or can you give me any youtube or tutorial link for this issue?

Hi @webma

I managed to get Bluetooth with BCM 4350C2 on Monterey and also on the latest Ventura 13.1 beta1 with Open Core 0.8.3

If you want to know how I did it, please write me an answer here. Greetings Fritz122

how did you do this? Can you take a picture
