If anyone has any objections, please let me know. ------------------ From: Andre Guedes commit 89cbb4da0abee2f39d75f67f9fd57f7410c8b65c upstream. This patch fixes the connection encryption key size information when the host is playing the peripheral role. We should set conn->enc_key_ size in hci_le_ltk_request_evt, otherwise it is left uninitialized.
