The kernel enforces this regardless of what kind of options were set for the socket. Perhaps it could be this one: https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git/commit/net/bluetooth/hci_conn.c?id=d5bb334a8e171b262e48f378bd2096c0ea458265 It looks like the test you mentioned it is just above the check for enc_key_size, though people mentioned it has been working so could it be that SSP is not enabled after all? -- Luiz Augusto von Dentz
