Why does BLE use &dyn?

[Frostie314159]

This is more a question than an issue, but is there a specific reason, why bleps doesn't use generics instead of a dynamic reference to an HCIConnection on the BLE struct?
If this has a specific reason, please let me know.
The BLE struct is likely only instantiated once in the entire application and monomorphization will likely even reduce code size here.

There is no particular reason for that. Feel free to file a PR
