The AF_BLUETOOTH socket type lacks support for specifying CID and address type in sockaddr_l2. These structure members have been present since 2009 and 2012 respectively:

https://git.kernel.org/cgit/bluetooth/bluez.git/commit/?id=3de95535
https://git.kernel.org/cgit/bluetooth/bluez.git/commit/?id=ba801fcd

The current version of the full structure can be found here:

https://git.kernel.org/cgit/bluetooth/bluez.git/tree/lib/l2cap.h?id=1b9e48f4#n40

The Python code in question can be found here:

AF_BLUETOOTH also lacks support for hci_channel in sockaddr_hci for BTPROTO_HCI sockets:

https://git.kernel.org/cgit/bluetooth/bluez.git/tree/lib/hci.h?h=5.37#n2340

This feature has been present in BlueZ since 2010:

https://git.kernel.org/cgit/bluetooth/bluez.git/commit/?id=12d02e7f

(Note that the latest BlueZ release includes a total of five different channels that should be supported)
