Hello, I have found another problem with this patch series.
I have there Nokia N900 device with Community SSU updates which acts as
both A2DP sink and A2DP source.
When I scan A2DP capabilities of Nokia N900 I get following output:
$ ./tools/avinfo XX:XX:XX:XX:XX:XX
Connecting ...
Stream End-Point #1: Audio Source
Media Codec: SBC
Channel Modes: Mono DualChannel Stereo JointStereo
Frequencies: 16Khz 32Khz 44.1Khz 48Khz
Subbands: 4 8
Blocks: 4 8 12 16
Bitpool Range: 2-64
Stream End-Point #2: Audio Sink
Media Codec: SBC
Channel Modes: Mono DualChannel Stereo JointStereo
Frequencies: 16Khz 32Khz 44.1Khz 48Khz
Subbands: 4 8
Blocks: 4 8 12 16
Bitpool Range: 2-64
$ qdbus --system org.bluez
/
/org
/org/bluez
/org/bluez/hci0
/org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX
/org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/fd2
/org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/player0
/org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/sep1
/org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/sep2
/org/bluez/test
So there is one SEP as Audio Source and one SEP as Audio Sink.
But when I ask sep1 and sep2 for UUID via dbus, I get that both are just
Audio Sinks:
$ qdbus --system org.bluez /org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/sep1 org.bluez.MediaEndpoint1.UUID
0000110a-0000-1000-8000-00805f9b34fb
$ qdbus --system org.bluez /org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/sep2 org.bluez.MediaEndpoint1.UUID
0000110a-0000-1000-8000-00805f9b34fb
So this is a clear bug.
