Reproduction I used two modules of the same chip from different manufacturers, the difference lies in the Bluetooth version, one module is BT5.0, the other is BT4.2, is it necessary to be compatible when registering the broadcast

I observed the same issue on Ubuntu 24.04 LTS ( Kernel: Linux 6.8.0-44-generic, BlueZ: 5.72):

dbus_next.errors.DBusError: Failed to register advertisement

btmon provides this information, but so far, I'm not sure how to fix it:

I will get back once I know more.
