And I now encountered a problem: the rfcomm connection can't be established. Only occasionally can the rfcomm connection be established. I'm using a USB dongle with Broadcom bluetooth chip inside of hci version 2.0. This dongle works well on my Laptop with linux-iamge-2.6.18. So I don't think the problem lies in the bluetooth dongle. My embeded arm platform runs the kernel 2.6.8-1 patched with patch from www.cirrus.com. But I don't think the patch file does anything related to bluetooth. Is there any way to use the lastest bluetooth kernel source on a arm platform with kernel 2.6.8-1 ? The typical output of hcidump is as following: ~ # hcidump -x -V HCI sniffer - Bluetooth packet analyzer ver 1.30 device: hci0 snap_len: 1028 filter: 0xffffffff < HCI Command: Create Connection (0x01|0x0005) plen 13 bdaddr 00:17:B0:B1:B2:CC ptype 0xcc18 rswitch 0x01 clkoffset 0x0000 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 > HCI Event: Command Status (0x0f) plen 4 Create Connection (0x01|0x0005) status 0x00 ncmd 1 > HCI Event: Connect Complete (0x03) plen 11 status 0x00 handle 12 bdaddr 00:17:B0:B1:B2:CC type ACL encrypt 0x00 < ACL data: handle 12 flags 0x02 dlen 12 L2CAP(s): Connect req: psm 3 scid 0x0040 > HCI Event: Max Slots Change (0x1b) plen 3 handle 12 slots 5 > ACL data: handle 12 flags 0x02 dlen 16 L2CAP(s): Connect rsp: dcid 0x0040 scid 0x0040 result 0 status 0 Connection successful < ACL data: handle 12 flags 0x02 dlen 16 L2CAP(s): Config req: dcid 0x0040 flags 0x00 clen 4 MTU 1024 > ACL data: handle 12 flags 0x02 dlen 16 L2CAP(s): Config req: dcid 0x0040 flags 0x00 clen 4 MTU 32772 < ACL data: handle 12 flags 0x02 dlen 14 L2CAP(s): Config rsp: scid 0x0040 flags 0x00 result 0 clen 0 Success > ACL data: handle 12 flags 0x02 dlen 17 > ACL data: handle 12 flags 0x01 dlen 1 L2CAP(s): Config rsp: scid 0x0040 flags 0x00 result 0 clen 4 Success MTU 1024 < ACL data: handle 12 flags 0x02 dlen 8 L2CAP(d): cid 0x0040 len 4 [psm 3] RFCOMM(s): SABM: cr 1 dlci 0 pf 1 ilen 0 fcs 0x1c > HCI Event: Number of Completed Packets (0x13) plen 5 handle 12 packets 4 > ACL data: handle 12 flags 0x02 dlen 8 L2CAP(d): cid 0x0040 len 4 [psm 3] RFCOMM(s): UA: cr 1 dlci 0 pf 1 ilen 0 fcs 0xd7 < ACL data: handle 12 flags 0x02 dlen 18 L2CAP(d): cid 0x0040 len 14 [psm 3] RFCOMM(s): PN CMD: cr 1 dlci 0 pf 0 ilen 10 fcs 0x70 mcc_len 8 dlci 18 frame_type 0 credit_flow 15 pri 7 ack_timer 0 frame_size 1019 max_retrans 0 credits 7 > ACL data: handle 12 flags 0x02 dlen 18 L2CAP(d): cid 0x0040 len 14 [psm 3] RFCOMM(s): PN RSP: cr 0 dlci 0 pf 0 ilen 10 fcs 0xaa mcc_len 8 dlci 18 frame_type 0 credit_flow 14 pri 7 ack_timer 0 frame_size 1019 max_retrans 0 credits 0 < ACL data: handle 12 flags 0x02 dlen 8 L2CAP(d): cid 0x0040 len 4 [psm 3] RFCOMM(s): SABM: cr 1 dlci 18 pf 1 ilen 0 fcs 0x32 > HCI Event: Number of Completed Packets (0x13) plen 5 handle 12 packets 2 /* it takes seconds here outputing nothing */ < ACL data: handle 12 flags 0x02 dlen 8 L2CAP(d): cid 0x0040 len 4 [psm 3] RFCOMM(s): DISC: cr 1 dlci 18 pf 1 ilen 0 fcs 0xd3 < ACL data: handle 12 flags 0x02 dlen 8 L2CAP(d): cid 0x0040 len 4 [psm 3] RFCOMM(s): DISC: cr 1 dlci 0 pf 1 ilen 0 fcs 0xfd < ACL data: handle 12 flags 0x02 dlen 12 L2CAP(s): Disconn req: dcid 0x0040 scid 0x0040 > ACL data: handle 12 flags 0x02 dlen 8 L2CAP(d): cid 0x0040 len 4 [psm 3] RFCOMM(s): UA: cr 1 dlci 18 pf 1 ilen 0 fcs 0xf9 > ACL data: handle 12 flags 0x02 dlen 8 L2CAP(d): cid 0x0040 len 4 [psm 3] RFCOMM(s): UA: cr 1 dlci 0 pf 1 ilen 0 fcs 0xd7 > ACL data: handle 12 flags 0x02 dlen 12 L2CAP(s): Disconn rsp: dcid 0x0040 scid 0x0040 > HCI Event: Number of Completed Packets (0x13) plen 5 handle 12 packets 3 < HCI Command: Disconnect (0x01|0x0006) plen 3 handle 12 reason 0x13 Reason: Remote User Terminated Connection > HCI Event: Command Status (0x0f) plen 4 Disconnect (0x01|0x0006) status 0x00 ncmd 1 > HCI Event: Disconn Complete (0x05) plen 4 status 0x00 handle 12 reason 0x16 Reason: Connection Terminated by Local Host The output of hciconfig -a is: hci0: Type: USB BD Address: 00:02:72:CA:DE:02 ACL MTU: 1017:8 SCO MTU: 64:0 UP RUNNING PSCAN ISCAN RX bytes:71 acl:0 sco:0 events:8 errors:0 TX bytes:31 acl:0 sco:0 commands:8 errors:0 Features: 0xff 0xff 0x8d 0xfe 0x9b 0xf9 0x00 0x80 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: Link mode: SLAVE ACCEPT Name: 'BCM92045DG_Class1' Class: 0x000000 Service Classes: Unspecified Device Class: Miscellaneous, HCI Ver: 2.0 (0x3) HCI Rev: 0x200a LMP Ver: 2.0 (0x3) LMP Subver: 0x4127 Manufacturer: Broadcom Corporation (15) Any tip or suggestion is welcome!
