Hi guys, Hello everyone. This is my first time to be here. I've met some problems when using bluetooth dongle on my board to connect to my bluetooth remote controller. I've ported bluez 4.60 to my board which runs on an OS with android honeycomb 3.2. The source code of bluez 4.60 is running on ubuntu 10.04 which is works fine for my laptop. I captured the connection establish process of my board with hcidump. It's like following, < HCI Command: Create Connection (0x01|0x0005) plen 13 bdaddr 00:21:4F:C3:0E:6D 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 40 bdaddr 00:21:4F:C3:0E:6D type ACL encrypt 0x00 < HCI Command: Read Remote Supported Features (0x01|0x001b) plen 2 handle 40 > HCI Event: Command Status (0x0f) plen 4 Read Remote Supported Features (0x01|0x001b) status 0x00 ncmd 0 > HCI Event: Page Scan Repetition Mode Change (0x20) plen 7 bdaddr 00:21:4F:C3:0E:6D mode 1 > HCI Event: Max Slots Change (0x1b) plen 3 handle 40 slots 5 > HCI Event: Command Status (0x0f) plen 4 Unknown (0x00|0x0000) status 0x00 ncmd 1 < HCI Command: Remote Name Request (0x01|0x0019) plen 10 bdaddr 00:21:4F:C3:0E:6D mode 2 clkoffset 0x0000 > HCI Event: Command Status (0x0f) plen 4 Remote Name Request (0x01|0x0019) status 0x00 ncmd 1 > HCI Event: Read Remote Supported Features (0x0b) plen 11 status 0x00 handle 40 Features: 0xff 0xff 0x8f 0xfe 0x9b 0xff 0x59 0x87 < HCI Command: Read Remote Extended Features (0x01|0x001c) plen 3 handle 40 page 1 > HCI Event: Command Status (0x0f) plen 4 Read Remote Extended Features (0x01|0x001c) status 0x00 ncmd 1 > HCI Event: Remote Name Req Complete (0x07) plen 255 status 0x00 bdaddr 00:21:4F:C3:0E:6D name 'ALPS_SPP-Module' > HCI Event: Read Remote Extended Features (0x23) plen 13 status 0x00 handle 40 page 1 max 1 Features: 0x01 0x00 0x00 0x00 0x00 0x00 0x00 0x00 < HCI Command: Authentication Requested (0x01|0x0011) plen 2 handle 40 > HCI Event: Command Status (0x0f) plen 4 Authentication Requested (0x01|0x0011) status 0x00 ncmd 1 > HCI Event: Link Key Request (0x17) plen 6 bdaddr 00:21:4F:C3:0E:6D < HCI Command: Link Key Request Negative Reply (0x01|0x000c) plen 6 bdaddr 00:21:4F:C3:0E:6D > HCI Event: Command Complete (0x0e) plen 10 Link Key Request Negative Reply (0x01|0x000c) ncmd 1 status 0x00 bdaddr 00:21:4F:C3:0E:6D > HCI Event: IO Capability Request (0x31) plen 6 bdaddr 00:21:4F:C3:0E:6D < HCI Command: IO Capability Request Reply (0x01|0x002b) plen 9 bdaddr 00:21:4F:C3:0E:6D capability 0x01 oob 0x00 auth 0x00 Capability: DisplayYesNo (OOB data not present) Authentication: No Bonding (No MITM Protection) > HCI Event: Command Complete (0x0e) plen 10 IO Capability Request Reply (0x01|0x002b) ncmd 1 status 0x00 bdaddr 00:21:4F:C3:0E:6D > HCI Event: IO Capability Response (0x32) plen 9 bdaddr 00:21:4F:C3:0E:6D capability 0x03 oob 0x00 auth 0x04 Capability: NoInputNoOutput (OOB data not present) Authentication: General Bonding (No MITM Protection) > HCI Event: User Confirmation Request (0x33) plen 10 bdaddr 00:21:4F:C3:0E:6D passkey 111087 < HCI Command: User Confirmation Request Reply (0x01|0x002c) plen 6 bdaddr 00:21:4F:C3:0E:6D > HCI Event: Command Complete (0x0e) plen 10 User Confirmation Request Reply (0x01|0x002c) ncmd 1 status 0x00 bdaddr 00:21:4F:C3:0E:6D < HCI Command: User Confirmation Request Negative Reply (0x01|0x002d) plen 6 bdaddr 00:21:4F:C3:0E:6D > HCI Event: Command Complete (0x0e) plen 10 User Confirmation Request Negative Reply (0x01|0x002d) ncmd 1 status 0x0c bdaddr 00:21:4F:C3:0E:6D Error: Command Disallowed > HCI Event: Simple Pairing Complete (0x36) plen 7 status 0x00 bdaddr 00:21:4F:C3:0E:6D > HCI Event: Link Key Notification (0x18) plen 23 bdaddr 00:21:4F:C3:0E:6D key 5FABBE1FD28579835CF7577BFBF3D345 type 4 Type: Unauthenticated Combination Key > HCI Event: Auth Complete (0x06) plen 3 status 0x00 handle 40 < HCI Command: Set Connection Encryption (0x01|0x0013) plen 3 handle 40 encrypt 0x01 > HCI Event: Command Status (0x0f) plen 4 Set Connection Encryption (0x01|0x0013) status 0x00 ncmd 1 > HCI Event: Encrypt Change (0x08) plen 4 status 0x00 handle 40 encrypt 0x01 < ACL data: handle 40 flags 0x02 dlen 10 L2CAP(s): Info req: type 2 > HCI Event: Number of Completed Packets (0x13) plen 5 handle 40 packets 1 > ACL data: handle 40 flags 0x02 dlen 16 L2CAP(s): Info rsp: type 2 result 0 Extended feature mask 0x0000 < ACL data: handle 40 flags 0x02 dlen 12 L2CAP(s): Connect req: psm 3 scid 0x0040 > HCI Event: Number of Completed Packets (0x13) plen 5 handle 40 packets 1 > ACL data: handle 40 flags 0x02 dlen 16 L2CAP(s): Connect rsp: dcid 0x0048 scid 0x0040 result 1 status 2 Connection pending -
