This updates transport select to link transports together before calling the "Select" method for each of them. The bluetoothctl log below shows a Broadcast Sink detecting 2 streams from a source and selecting both of them. After the first transport is acquired, the link is created and the first transport goes active. client/bluetoothctl [bluetooth]# endpoint.register 00001851-0000-1000-8000-00805f9b34fb 0x06 [/local/endpoint/ep0] Auto Accept (yes/no): y [/local/endpoint/ep0] Max Transports (auto/value): a [/local/endpoint/ep0] Locations: 1 [/local/endpoint/ep0] Supported Context (value): 1 Capabilities: 03 01 ff 00 02 02 03 05 04 1a 00 f0 00 02 03 01 Metadata: [bluetooth]# Endpoint /local/endpoint/ep0 registered [bluetooth]# scan on [bluetooth]# [NEW] Device 17:7A:80:64:A7:93 17-7A-80-64-A7-93 [17-7A-80-64-A7-93]# [NEW] Transport /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis1/fd0 [17-7A-80-64-A7-93]# [NEW] Transport /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis2/fd1 [17-7A-80-64-A7-93]# transport.select /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis1/fd0 /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis2/fd1 [17-7A-80-64-A7-93]# [CHG] Transport /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis1/fd0 State: broadcasting [17-7A-80-64-A7-93]# [CHG] Transport /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis2/fd1 State: broadcasting [17-7A-80-64-A7-93]# transport.acquire /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis1/fd0 [17-7A-80-64-A7-93]# [CHG] Transport /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis1/fd0 Links: /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis2/fd1 [17-7A-80-64-A7-93]# Transport /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis1/fd0 acquiring complete [17-7A-80-64-A7-93]# Acquire successful: fd 8 MTU 40:0 [17-7A-80-64-A7-93]# [CHG] Transport /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis1/fd0 State: active The btmon log shows that sync has been established with both BISes: < HCI Command: LE Broadcast Isochronous Group Create Sync (0x08|0x006b) BIG Handle: 0x00 BIG Sync Handle: 0x0000 Encryption: Unencrypted (0x00) Broadcast Code[16]: 00000000000000000000000000000000 Maximum Number Subevents: 0x00 Timeout: 20000 ms (0x07d0) Number of BIS: 2 BIS ID: 0x01 BIS ID: 0x02 > HCI Event: Command Status (0x0f) plen 4 LE Broadcast Isochronous Group Create Sync (0x08|0x006b) ncmd 1 Status: Success (0x00) > HCI Event: LE Meta Event (0x3e) plen 19 LE Broadcast Isochronous Group Sync Estabilished (0x1d) Status: Success (0x00) BIG Handle: 0x00 Transport Latency: 0 us (0x000000) NSE: 3 BN: 1 PTO: 1 IRC: 3 Maximum PDU: 40 ISO Interval: 10.00 msec (0x0008) Connection Handle #0: 6 Connection Handle #1: 7 < HCI Command: LE Setup Isochronous Data Path (0x08|0x006e) plen 13 Handle: 6 Data Path Direction: Output (Controller to Host) (0x01) Data Path: HCI (0x00) Coding Format: Transparent (0x03) Company Codec ID: Ericsson Technology Licensing (0) Vendor Codec ID: 0 Controller Delay: 0 us (0x000000) Codec Configuration Length: 0 Codec Configuration[0]: > HCI Event: Command Complete (0x0e) plen 6 LE Setup Isochronous Data Path (0x08|0x006e) ncmd 1 Status: Success (0x00) Handle: 6 < HCI Command: LE Setup Isochronous Data Path (0x08|0x006e) plen 13 Handle: 7 Data Path Direction: Output (Controller to Host) (0x01) Data Path: HCI (0x00) Coding Format: Transparent (0x03) Company Codec ID: Ericsson Technology Licensing (0) Vendor Codec ID: 0 Controller Delay: 0 us (0x000000) Codec Configuration Length: 0 Codec Configuration[0]: > HCI Event: Command Complete (0x0e) plen 6 LE Setup Isochronous Data Path (0x08|0x006e) ncmd 1 Status: Success (0x00) Handle: 7 The second transport can then be acquired and it will go straight to active, since the fd has already been set: [17-7A-80-64-A7-93]# transport.acquire /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis2/fd1 [17-7A-80-64-A7-93]# [CHG] Transport /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis2/fd1 Links: /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis1/fd0 [17-7A-80-64-A7-93]# Transport /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis2/fd1 acquiring complete [17-7A-80-64-A7-93]# Acquire successful: fd 9 MTU 40:0 [17-7A-80-64-A7-93]# [CHG] Transport /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis2/fd1 State: active The transports can them be released one by one: [17-7A-80-64-A7-93]# transport.release /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis1/fd0 [17-7A-80-64-A7-93]# Transport fd disconnected [17-7A-80-64-A7-93]# [CHG] Transport /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis1/fd0 State: idle [17-7A-80-64-A7-93]# Release successful [17-7A-80-64-A7-93]# transport.release /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis2/fd1 [17-7A-80-64-A7-93]# Transport fd disconnected [17-7A-80-64-A7-93]# [CHG] Transport /org/bluez/hci0/dev_17_7A_80_64_A7_93/bis2/fd1 State: idle [17-7A-80-64-A7-93]# Release successful --- client/player.c | 47 +++++++++++++++++++++++++++++++++++++++++------ 1 file changed, 41 insertions(+), 6 deletions(-)
