Hi Szymon, Thanks for the feedback. Here are the btmon logs when the device pairs successfully with the SMP Kernel change. The behaviour is similar with Bluez 5.23, that comes default with Debian Jessie. Around 52 seconds mark in the logs, soon after SMP: Pairing Random (0x04) len 16, LE Start Encryption (0x08|0x0019) plen 28 is seen. and then around 55 seconds, SMP: Encryption Information SMP: Master Identification SMP: Identity Address Information SMP: Signing Information messages are seen. Logs below: Software Baseline: Kernel 5.41, Bluez 5.42 FYI: BTMon Logs with the issue is included in my original message http://marc.info/?l=linux-bluetooth&m=147356320523622&w=2 **************** Begin BTMon Logs **************************** Bluez Version 5.41 root@Deb-Jessie:~# btmon Bluetooth monitor ver 5.41 = New Index: 44:1C:A8:6C:8F:5E (Primary,UART,hci0) [hci0] 0.513794 < HCI Command: LE Set Random Address (0x08|0x0005) plen 6 [hci0] 46.048934 Address: 27:5A:29:B2:21:56 (Non-Resolvable) > HCI Event: Command Complete (0x0e) plen 4 [hci0] 46.056068 LE Set Random Address (0x08|0x0005) ncmd 1 Status: Success (0x00) > HCI Event: Command Complete (0x0e) plen 4 [hci0] 46.056082 LE Set Random Address (0x08|0x0005) ncmd 1 Status: Success (0x00) < HCI Command: LE Set Scan Parameters (0x08|0x000b) plen 7 [hci0] 46.056152 Type: Active (0x01) Interval: 11.250 msec (0x0012) Window: 11.250 msec (0x0012) Own address type: Random (0x01) Filter policy: Accept all advertisement (0x00) > HCI Event: Command Complete (0x0e) plen 4 [hci0] 46.060881 LE Set Scan Parameters (0x08|0x000b) ncmd 1 Status: Success (0x00) < HCI Command: LE Set Scan Enable (0x08|0x000c) plen 2 [hci0] 46.060960 Scanning: Enabled (0x01) Filter duplicates: Enabled (0x01) > HCI Event: Command Complete (0x0e) plen 4 [hci0] 46.065508 LE Set Scan Enable (0x08|0x000c) ncmd 1 Status: Success (0x00) @ Discovering: 0x01 (7) > HCI Event: LE Meta Event (0x3e) plen 35 [hci0] 46.133086 LE Advertising Report (0x02) Num reports: 1 Event type: Connectable undirected - ADV_IND (0x00) Address type: Random (0x01) Address: 74:9A:AA:38:11:48 (Resolvable) Data length: 23 Flags: 0x06 LE General Discoverable Mode BR/EDR Not Supported Company: Apple, Inc.
