1) BTPROTO_HCI addresses only expect string identifiers on NetBSD and DragonFly: https://github.com/python/cpython/blob/2e0a920e9eb540654c0bb2298143b00637dc5961/Modules/socketmodule.c#L1931 But of course this is true on FreeBSD too. (DragonFly inherited the BT stack from FreeBSD!) For example this is how hccontrol creates an address: https://github.com/freebsd/freebsd/blob/6bb9221a9b865ee432269099f341e4230a6cbcd4/usr.sbin/bluetooth/hccontrol/hccontrol.c#L115-L129 So currently it is not possible to bind an HCI socket (without using FFI to directly use the libc bind function) :( 2) BTPROTO_SCO is excluded on FreeBSD: https://github.com/python/cpython/blob/2e0a920e9eb540654c0bb2298143b00637dc5961/Modules/socketmodule.c#L1953 But SCO has been supported since 2008: https://github.com/freebsd/freebsd/commit/bb4c6de0cf336d006e41521cbbd4706f60a0dfe0

But of course this is true on FreeBSD too. (DragonFly inherited the BT stack from FreeBSD!)
For example this is how hccontrol creates an address:
https://github.com/freebsd/freebsd/blob/6bb9221a9b865ee432269099f341e4230a6cbcd4/usr.sbin/bluetooth/hccontrol/hccontrol.c#L115-L129

So currently it is not possible to bind an HCI socket (without using FFI to directly use the libc bind function) :(

2) BTPROTO_SCO is excluded on FreeBSD: https://github.com/python/cpython/blob/2e0a920e9eb540654c0bb2298143b00637dc5961/Modules/socketmodule.c#L1953

But SCO has been supported since 2008: https://github.com/freebsd/freebsd/commit/bb4c6de0cf336d006e41521cbbd4706f60a0dfe0
