Subject: [Bluez-devel] avrcp volume control
Date: Thu, 15 Dec 2005 00:01:37 -0700 [thread overview]
Message-ID: <43A114D1.4000506@xmission.com> (raw)
Guys,
My best guess at volume control over avrcp is to send volume up/down
commands to the panel subunit on the headset. It doesn't seems to do
anything (no ack/nak or change in volume on bluetake iphono mini). I was
able to confirm the operand codes with a helpful 1394 developer by the way.
Does anyone here on the list know how this really should be framed so we
can control the headset volume?
The packet I'm sending to raise the volume looks something like this in hex:
20 transaction_label=2, packet type=single, cr=command_frame, ipid=0
11 pid lo
0e pid hi
00 ctype = passthrough command
48 subunit type=panel(9), subunit id=0
7c opcode? (this is what the headset always puts here in its cmds)
41 volume-up lo
00 volume-up hi
help :)
Brad
