Hello, I have a CHIPSET BROADCOM BCM 20702 bluetooth dongle. The bluetooths dongle is recognized in FreeBSD. Here are the steps I took to have my GVAUDIO Bluetooth recognized. I followed the steps of the link : https://notebook.niklaas.eu/freebsd-bluetooth-keyboard/ I summarize : I did 1) sudo service bluetooth start ubt0 2) I modified my hosts (/etc/bluetooth/hosts) 58:b3:fc:e7:3c:fa GVAUDIO 3) sudo hccontrol -n ubt0hci inquiry Inquiry result, num_responses=1 Inquiry result #0 BD_ADDR: GVAUDIO Page Scan Rep. Mode: 0x1 Page Scan Period Mode: 00 Page Scan Mode: 00 Class: 24:04:14 Clock offset: 0x3ebd Inquiry complete. Status: No error [00] 4) sudo service hcsecd onestart sudo service bthidd onestart sudo service sdpd onestart 5) sudo bash -c "bthidcontrol -a GVAUDIO query >> /etc/bluetooth/bthidd.conf" Could not perform SDP query on the device 58:b3:fc:e7:3c:fa. Attribute not found (87) PROBLEM Attribute not found //I launched hcidump -x then bthidcontrol -a GVAUDIO query >> /etc/bluetooth/bthidd.conf 6) sudo hcidump -x HCIDump - HCI packet analyzer ver 1.5 device: any snap_len: 65535 filter: 0xffffffffffffffff < HCI Command: Create Connection(0x01|0x0005) plen 13 FA 3C E7 FC B3 58 18 CC 01 00 00 00 01 > HCI Event: Command Status(0x0f) plen 4 00 01 05 04 > HCI Event: Connect Complete(0x03) plen 11 00 0C 00 FA 3C E7 FC B3 58 01 00 < HCI Command: Write Link Policy Settings(0x02|0x000d) plen 4 0C 00 05 00 < ACL data: handle 0x000c flags 0x02 dlen 12 L2CAP(s): Connect req: psm 1 scid 0x004b > HCI Event: Command Complete(0x0e) plen 6 01 0D 08 00 0C 00 > HCI Event: Page Scan Repetition Mode Change(0x20) plen 7 FA 3C E7 FC B3 58 01 > HCI Event: Max Slots Change(0x1b) plen 3 0C 00 05 > ACL data: handle 0x000c flags 0x02 dlen 16 L2CAP(s): Connect rsp: dcid 0x0100 scid 0x004b result 1 status 2 > ACL data: handle 0x000c flags 0x02 dlen 16 L2CAP(s): Connect rsp: dcid 0x0100 scid 0x004b result 0 status 0 < ACL data: handle 0x000c flags 0x02 dlen 12 L2CAP(s): Config req: dcid 0x0100 flags 0x0000 clen 0 > ACL data: handle 0x000c flags 0x02 dlen 16 L2CAP(s): Config req: dcid 0x004b flags 0x0000 clen 4 MTU 48 < ACL data: handle 0x000c flags 0x02 dlen 14 L2CAP(s): Config rsp: scid 0x0100 flags 0x0000 result 0 clen 0 > HCI Event: Number of Completed Packets(0x13) plen 5 01 0C 00 02 00 020 > ACL data: handle 0x000c flags 0x02 dlen 14 L2CAP(s): Config rsp: scid 0x004b flags 0x0000 result 0 clen 0 < ACL data: handle 0x000c flags 0x02 dlen 39 L2CAP(d): cid 0x100 len 35 [psm 1] SDP SSA Req: tid 0x0 len 0x1e pat uuid-16 0x1124 (HID) max 0xffff aid(s) 0x0004 (ProtocolDescList) 0x000d (IconURL) 0x0205 (unknown) 0x0206 (unknown) 0x0209 (unknown) 0x020d (unknown) cont 00 > HCI Event: Number of Completed Packets(0x13) plen 5 01 0C 00 02 00 > ACL data: handle 0x000c flags 0x02 dlen 14 L2CAP(d): cid 0x4b len 10 [psm 1] SDP SSA Rsp: tid 0x0 len 0x5 cnt 0x2 cont 00 < ACL data: handle 0x000c flags 0x02 dlen 12 L2CAP(s): Disconn req: dcid 0x0100 scid 0x004b > ACL data: handle 0x000c flags 0x02 dlen 12 L2CAP(s): Disconn rsp: dcid 0x0100 scid 0x004b > HCI Event: Number of Completed Packets(0x13) plen 5 01 0C 00 01 00 < HCI Command: Disconnect(0x01|0x0006) plen 3 0C 00 13 > HCI Event: Command Status(0x0f) plen 4 00 01 06 04 > HCI Event: Disconn Complete(0x05) plen 4 00 0C 00 16 // 7) sudo sdpcontrol -a GVAUDIO browse PROBLEM no message is executed without errors. //I launched hcidump -x then sdpcontrol -a GVAUDIO browse 8) sudo hcidump -x HCIDump - HCI packet analyzer ver 1.5 device: any snap_len: 65535 filter: 0xffffffffffffffff > HCI Event: Connect Complete(0x03) plen 11 00 0B 00 FA 3C E7 FC B3 58 01 00 < HCI Command: Write Link Policy Settings(0x02|0x000d) plen 4 0B 00 05 00 < ACL data: handle 0x000b flags 0x02 dlen 12 L2CAP(s): Connect req: psm 1 scid 0x004f > HCI Event: Command Complete(0x0e) plen 6 01 0D 08 00 0B 00 > HCI Event: Page Scan Repetition Mode Change(0x20) plen 7 FA 3C E7 FC B3 58 01 > HCI Event: Max Slots Change(0x1b) plen 3 0B 00 05 > ACL data: handle 0x000b flags 0x02 dlen 16 L2CAP(s): Connect rsp: dcid 0x0180 scid 0x004f result 1 status 2 > ACL data: handle 0x000b flags 0x02 dlen 16 L2CAP(s): Connect rsp: dcid 0x0180 scid 0x004f result 0 status 0 < ACL data: handle 0x000b flags 0x02 dlen 12 L2CAP(s): Config req: dcid 0x0180 flags 0x0000 clen 0 > ACL data: handle 0x000b flags 0x02 dlen 16 L2CAP(s): Config req: dcid 0x004f flags 0x0000 clen 4 MTU 48 < ACL data: handle 0x000b flags 0x02 dlen 14 L2CAP(s): Config rsp: scid 0x0180 flags 0x0000 result 0 clen 0 > HCI Event: Number of Completed Packets(0x13) plen 5 01 0B 00 02 00 > ACL data: handle 0x000b flags 0x02 dlen 14 L2CAP(s): Config rsp: scid 0x004f flags 0x0000 result 0 clen 0 < ACL data: handle 0x000b flags 0x02 dlen 33 L2CAP(d): cid 0x180 len 29 [psm 1] SDP SSA Req: tid 0x0 len 0x18 pat uuid-16 0x1002 (PubBrwsGrp) max 0xffff aid(s) 0x0000 (SrvRecHndl) 0x0001 (SrvClassIDList) 0x0004 (ProtocolDescList) 0x0009 (BTProfileDescList) cont 00 020 > HCI Event: Number of Completed Packets(0x13) plen 5 01 0B 00 02 00 > ACL data: handle 0x000b flags 0x02 dlen 14 L2CAP(d): cid 0x4f len 10 [psm 1] SDP SSA Rsp: tid 0x0 len 0x5 cnt 0x2 cont 00 < ACL data: handle 0x000b flags 0x02 dlen 12 L2CAP(s): Disconn req: dcid 0x0180 scid 0x004f > ACL data: handle 0x000b flags 0x02 dlen 12 L2CAP(s): Disconn rsp: dcid 0x0180 scid 0x004f > HCI Event: Number of Completed Packets(0x13) plen 5 01 0B 00 01 00 < HCI Command: Disconnect(0x01|0x0006) plen 3 0B 00 13 > HCI Event: Command Status(0x0f) plen 4 00 01 06 04 > HCI Event: Disconn Complete(0x05) plen 4 00 0B 00 16 How can I correct in 5) PROBLEM Attribute not found ?
