Hello all, I hope i am using correctly that mail list :) I am looking for solution for 1 week and did not find anything :/ and i do not know where to ask :) ! here is my problem, I have an issue with a serial port module over bluetooth (HC-06 / linvor) for arduino Rpi etc.. . it worked correctly with bluez 4 (i do not the version) . I am using debian 8, kernel 3.16.0-14-amd64 and bluez 5.43 I can pair/trust the module, but the connection is not possible with the gui. when using bluetoothctl and try to connect i get: Attempting to connect to 00:12:03:10:71:96 [CHG] Device 00:12:03:10:71:96 Connected: yes [CHG] Device 00:12:03:10:71:96 ServicesResolved: yes Failed to connect: org.bluez.Error.NotAvailable [CHG] Device 00:12:03:10:71:96 ServicesResolved: no [CHG] Device 00:12:03:10:71:96 Connected: no in the same time i used btmon and here it told me: < ACL Data TX: Handle 46 flags 0x00 dlen 12 [hci0] 2668.614925 L2CAP: Disconnection Request (0x06) ident 4 len 4 Destination CID: 67 Source CID: 64 > HCI Event: Number of Completed Packets (0x13) plen 5 [hci0] 2668.627630 Num handles: 1 Handle: 46 Count: 1 > ACL Data RX: Handle 46 flags 0x02 dlen 12 [hci0] 2668.691614 L2CAP: Disconnection Response (0x07) ident 4 len 4 Destination CID: 67 Source CID: 64 < HCI Command: Read RSSI (0x05|0x0005) plen 2 [hci0] 2669.370862 Handle: 46 > HCI Event: Command Complete (0x0e) plen 7 [hci0] 2669.373677 Read RSSI (0x05|0x0005) ncmd 1 Status: Success (0x00) Handle: 46 RSSI: 0 dBm (0x00) < HCI Command: Read Link Quality (0x05|0x0003) plen 2 [hci0] 2669.373782 Handle: 46 > HCI Event: Command Complete (0x0e) plen 7 [hci0] 2669.375744 Read Link Quality (0x05|0x0003) ncmd 1 Status: Success (0x00) Handle: 46 Link quality: 0xff < HCI Command: Read Transmit Power Level (0x03|0x002d) plen 3 [hci0] 2669.375926 Handle: 46 Type: Current Transmit Power Level (0x00) > HCI Event: Command Complete (0x0e) plen 7 [hci0] 2669.379749 Read Transmit Power Level (0x03|0x002d) ncmd 1 Status: Success (0x00) Handle: 46 TX power: -1 dBm < HCI Command: Read RSSI (0x05|0x0005) plen 2 [hci0] 2670.372415 Handle: 46 > HCI Event: Command Complete (0x0e) plen 7 [hci0] 2670.374710 Read RSSI (0x05|0x0005) ncmd 1 Status: Success (0x00) Handle: 46 RSSI: 0 dBm (0x00) < HCI Command: Read Link Quality (0x05|0x0003) plen 2 [hci0] 2670.374814 Handle: 46 > HCI Event: Command Complete (0x0e) plen 7 [hci0] 2670.376789 Read Link Quality (0x05|0x0003) ncmd 1 Status: Success (0x00) Handle: 46 Link quality: 0xff < HCI Command: Read Transmit Power Level (0x03|0x002d) plen 3 [hci0] 2670.376977 Handle: 46 Type: Current Transmit Power Level (0x00) > HCI Event: Command Complete (0x0e) plen 7 [hci0] 2670.379784 Read Transmit Power Level (0x03|0x002d) ncmd 1 Status: Success (0x00) Handle: 46 TX power: -1 dBm < HCI Command: Disconnect (0x01|0x0006) plen 3 [hci0] 2670.692650 Handle: 46 Reason: Remote User Terminated Connection (0x13) > HCI Event: Command Status (0x0f) plen 4 [hci0] 2670.698800 Disconnect (0x01|0x0006) ncmd 1 Status: Success (0x00) > HCI Event: Disconnect Complete (0x05) plen 4 [hci0] 2670.778725 Status: Success (0x00) Handle: 46 Reason: Connection Terminated By Local Host (0x16) @ Device Disconnected: 00:12:03:10:71:96 (0) reason 2 i did not find interesting log in the /var/log/ files does anyone have an idea to get more logs ?
