Tools for AVDTP / AVCTP qualification

Tools for AVDTP / AVCTP qualification

[Nick Pelly]

Hi,

Do there exist any tools to help pass Bluez AVDTP and AVCTP stack qualification?

Looking at the test spec it seems some command line tools might be
handy. I am thinking along the lines of l2test, hcitool etc. I'll be
writing some similar for AVDTP and AVCTP unless there are already some
floating around?

Cheers,
Nick

we only have avinfo at the moment since the whole AVDTP and AVCTP is
highly integrated into our audio plugin. At some point we were thinking
of doing a AVDTP kernel layer, but never got to it and also it was not
really needed. Putting AVCTP in the kernel would make no sense anyway.

So instead of implementing the whole protocol again to just pass the
qualification tests would be totally stupid. And to be honest the
testing should be just working fine with establishing or accepting
proper A2DP connection.

For the A2DP tests of the PTS suite, I just used GStreamer's gst-launch
with a proper pipeline.

Following up on this old thread,

The AVDTP and AVCTP SIG test specification documents explain a
complex, automated testing environment where an 'upper tester' makes
method or IPC calls into your stack to cause it to run through various
AVDTP/AVCTP request/responses with the 'lower tester'. This was what
my original email was about - if there were tools to interface with
the upper tester.

What those documents do not explain is that it seems for A2DP and
AVRCP products you can submit frontline sniff traces of the PTS tests
as evidence of AVDTP/AVCTP compatibility. So in our case we don't need
the tools. Hope this helps others trying to wade through SIG
bureaucracy.

so since the Frontline software can read BTSnoop format HCI based
traces, it would be nice if we can sent these in. Especially since
hcidump can write these natively. So no complex setups.
