Hi Nordic!
I'm evaluating the zephyr samples "broadcast_audio_sink" and "broadcast_audio_source". Running these two on two separate nrf5340 audio dev boards works fine. But, for my testning purposes I need to use another source, e.g. the nrf5340 audio application running as a source. Using this source or a number of other sources out there (both nordic and non-nordic based sources) triggers the following problem on the "broadcast_audio_sink":
Scanning for broadcast sources Waiting for Broadcaster Found broadcaster with ID 0x4276E8 and addr CC:89:6C:42:01:AF (random) and sid 0x01 broadcaster_broadcast_id = 0x4276E8 Attempting to PA sync to the broadcaster with id 0x4276E8 Waiting for PA synced Found broadcaster with ID 0x4276E8 and addr CC:89:6C:42:01:AF (random) and sid 0x01 broadcaster_broadcast_id = 0x4276E8 PA sync 0x200076d4 synced for broadcast sink with broadcast ID 0x4276E8 Broadcast source PA synced, creating Broadcast Sink Receive state updated, pa sync state: 2 Broadcast Sink created, waiting for BASE Received BASE with 1 subgroups from broadcast sink 0x20007a78 Could not get codec configuration: -12 Failed to parse subgroups: 0 Failed to find a valid BIS Broadcast sink (0x20007a78) is syncable, BIG not encrypted Received BASE with 1 subgroups from broadcast sink 0x20007a78 Could not get codec configuration: -12 Failed to parse subgroups: 0 Failed to find a valid BIS
Comparing with the "broadcast_audio_source" sample the (working) output is:
Waiting for Broadcaster Found broadcaster with ID 0x231468 and addr 34:9A:FD:CD:A0:64 (random) and sid 0x00 broadcaster_broadcast_id = 0x231468 Attempting to PA sync to the broadcaster with id 0x231468 Waiting for PA synced Found broadcaster with ID 0x231468 and addr 34:9A:FD:CD:A0:64 (random) and sid 0x00 broadcaster_broadcast_id = 0x231468 Found broadcaster with ID 0x231468 and addr 34:9A:FD:CD:A0:64 (random) and sid 0x00 broadcaster_broadcast_id = 0x231468 Found broadcaster with ID 0x231468 and addr 34:9A:FD:CD:A0:64 (random) and sid 0x00 broadcaster_broadcast_id = 0x231468 Found broadcaster with ID 0x231468 and addr 34:9A:FD:CD:A0:64 (random) and sid 0x00 broadcaster_broadcast_id = 0x231468 PA sync 0x20007604 synced for broadcast sink with broadcast ID 0x231468 Broadcast source PA synced, creating Broadcast Sink Receive state updated, pa sync state: 2 Broadcast Sink created, waiting for BASE Receive state updated, pa sync state: 2 subgroup 0 bis_sync: 0x00000000 Received BASE with 1 subgroups from broadcast sink 0x200079a8 bis_index_bitfield = 0x00000002 Broadcast sink (0x200079a8) is syncable, BIG not encrypted BASE received, waiting for syncable Waiting for broadcast code Waiting for BIS sync request Syncing to broadcast with bitfield: 0x00000002 = 0x00000002 (bis_index) & 0xffffffff (req_bis_sync), stream_count = 1 Waiting for stream(s) started Receive state updated, pa sync state: 2 subgroup 0 bis_sync: 0x00000002 Stream 0x20000fc8 connected Stream 0x20000fc8 started
Looking into the code, this is where it fails (relating to the first log above):
err = bt_bap_base_subgroup_codec_to_codec_cfg(subgroup, &codec_cfg);
if (err != 0) {
printk("Could not get codec configuration: %d\n", err);
return true;
}
Any idea what this could be related to? Anything to change on the source side?
Best regards,
Henrik
