I’m getting connection failures with Bluetooth headphones on Fedora 42 (installed fresh on a new Laptop 13 (AMD Ryzen 7040Series)).
dmesg shows this message twice each time I try to connect:
hci0: ACL packet for unknown connection handle 3837
I’ve confirmed I can connect to the headphones with other devices.
I’m also able to connect to other speakers from the Framework 13.
This is all the bluetooth output in dmesg. Could “Enhanced Setup Synchronous Connection” be an issue?
