Hi, I'm trying to use bluez 5.2 release to connect with my LE device, which is one proximity alert device. It always reports "PIN or Key Missing" and then disconnect immediately. Btmon logs and function calls is shown below: Bluetooth monitor ver 5.3 = New Index: 00:1A:7D:DA:71:05 (BR/EDR,USB,hci0) [hci0] 0.777425 > HCI Event: LE Meta Event (0x3e) plen 26 [hci0] 1.866952 LE Advertising Report (0x02) Num reports: 1 Event type: Connectable undirected - ADV_IND (0x00) Address type: Public (0x00) Address: 80:CF:41:6D:0A:66 (OUI 80-CF-41) Data length: 14 Name (complete): Lenovo S880i RSSI: -75 dBm @ Device Found: 80:CF:41:6D:0A:66 (1) rssi -75 flags 0x0000 0d 09 4c 65 6e 6f 76 6f 20 53 38 38 30 69 ..Lenovo S880i > HCI Event: LE Meta Event (0x3e) plen 19 [hci0] 2.454951 LE Advertising Report (0x02) Num reports: 1 Event type: Connectable undirected - ADV_IND (0x00) Address type: Public (0x00) Address: 00:17:EA:91:8C:78 (OUI 00-17-EA) Data length: 7 Flags: 0x06 LE General Discoverable Mode BR/EDR Not Supported 16-bit Service UUIDs (complete): 1 entry Link Loss (0x1803) RSSI: -69 dBm @ Device Found: 00:17:EA:91:8C:78 (1) rssi -69 flags 0x0000 02 01 06 03 03 03 18 ....... < HCI Command: LE Set Scan Enable (0x08|0x000c) plen 2 [hci0] 2.455206 Scanning: Disabled (0x00) Filter duplicates: Disabled (0x00) > HCI Event: LE Meta Event (0x3e) plen 30 [hci0] 2.456922 LE Advertising Report (0x02) Num reports: 1 Event type: Scan response - SCAN_RSP (0x04) Address type: Public (0x00) Address: 00:17:EA:91:8C:78 (OUI 00-17-EA) Data length: 18 Name (complete): UJuicer Alert TX power: -6 dBm RSSI: -69 dBm @ Device Found: 00:17:EA:91:8C:78 (1) rssi -69 flags 0x0000 0e 09 55 4a 75 69 63 65 72 20 41 6c 65 72 74 02 ..UJuicer Alert. 0a fa .. > HCI Event: Command Complete (0x0e) plen 4 [hci0] 2.461946 LE Set Scan Enable (0x08|0x000c) ncmd 1 Status: Success (0x00) @ Discovering: 0x00 (6) < HCI Command: LE Create Connection (0x08|0x000d) plen 25 [hci0] 2.499924 Scan interval: 60.000 msec (0x0060) Scan window: 30.000 msec (0x0030) Filter policy: White list is not used (0x00) Peer address type: Public (0x00) Address: 00:17:EA:91:8C:78 (OUI 00-17-EA) Own address type: Public (0x00) Min connection interval: 50.00 msec (0x0028) Max connection interval: 70.00 msec (0x0038) Connection latency: 0x0000 Supervision timeout: 420 msec (0x002a) Min connection length: 0.000 msec (0x0000) Max connection length: 0.000 msec (0x0000) > HCI Event: Command Status (0x0f) plen 4 [hci0] 2.503950 LE Create Connection (0x08|0x000d) ncmd 1 Status: Success (0x00) > HCI Event: LE Meta Event (0x3e) plen 19 [hci0] 5.723917 LE Connection Complete (0x01) Status: Success (0x00) Handle: 71 Role: Master (0x00) Peer address type: Public (0x00) Address: 00:17:EA:91:8C:78 (OUI 00-17-EA) Connection interval: 70.00 msec (0x0038) Connection latency: 0.00 msec (0x0000) Supervision timeout: 420 msec (0x002a) Master clock accuracy: 0x00 < HCI Command: LE Start Encryption (0x08|0x0019) plen 28 [hci0] 5.724000 Handle: 71 Random number: 8c126b665d2de279 Encryption diversifier: 0x3f55 Long term key: dcd74a1a07f653c0e27f65888debcbe5 @ Device Connected: 00:17:EA:91:8C:78 (1) flags 0x0000 > HCI Event: Command Status (0x0f) plen 4 [hci0] 5.733922 LE Start Encryption (0x08|0x0019) ncmd 1 Status: Success (0x00) > ACL Data RX: Handle 71 flags 0x02 dlen 6 [hci0] 5.835521 SMP: Security Request (0x0b) len 1 Authentication requirement: Bonding - MITM (0x05) > HCI Event: Encryption Change (0x08) plen 4 [hci0] 6.115911 Status: PIN or Key Missing (0x06) Handle: 71 Encryption: Disabled (0x00) < HCI Command: Disconnect (0x01|0x0006) plen 3 [hci0] 6.115942 Handle: 71 Reason: Authentication Failure (0x05) > HCI Event: Command Status (0x0f) plen 4 [hci0] 6.117913 Disconnect (0x01|0x0006) ncmd 1 Status: Success (0x00) > HCI Event: Disconnect Complete (0x05) plen 4 [hci0] 6.186914 Status: Success (0x00) Handle: 71 Reason: Connection Terminated By Local Host (0x16) @ Device Disconnected: 00:17:EA:91:8C:78 (1) reason 2 Some called function log: received_data event = 0x1, index = 0x0, length = 0x4 stop_passive_scanning_complete device_connect_le after bt_io_connect received_data event = 0x13, index = 0x0, length = 0x2 discovering_callback received_data event = 0xb, index = 0x0, length = 0xd connected_callback adapter_get_device adapter_find_device adapter_add_connection device_add_connection device_set_temporary after adapter_add_connection received_data event = 0xc, index = 0x0, length = 0x8 dev_disconnected adapter_find_device bonding_complete adapter_find_device device_bonding_complete att_connect_cb att_error_cb Thanks. -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
