Hi,
I've been testing out the WiFi Display service registration patch set.
Some observations (Tomasz, mostly I shared these with you already,
just documenting here):
The documentation could be improved in a couple of ways:
* First, talking about "IEs" as the byte array argument to
RegisterPeerService is a bit confusing at least for someone looking at
the Wi-Di spec: the argument connman expects is actually just the
Device Information _subelement_ without the Information Element
envelope (Tomasz mentioned offline that the other subelements can be
appended to the byte array as well: that should be documented too).
* There could be a little more overview: E.g. what typically happens
after registration (when another device makes a P2P connection).
* I believe the idea was that to change values in the byte array, I
should unregister and then re-register: this should be mentioned.
Then, I had limited success with connecting from an android device to
a service I registered with connman: According to Tomasz it looks like
android picks PIN as the authentication method and that's not yet
implemented in connman: connman agent does shows a
"RequestPeerAuthorization" question but the "yes" response does not
succeed:
> Agent RequestPeerAuthorization peer_106f3f7b0f9a_12683f467bfb
>
> Accept connection (yes/no)? yes
> Agent ReportPeerError peer_106f3f7b0f9a_12683f467bfb
> connect-failed
> connmanctl> Retry (yes/no)? no
Note how it also tries to retry -- Tomasz mentioned that is probably a
bug: it should not retry because the connection was started by the
other end.
And last, I have a couple of crash backtraces:
This one happened when the process that registered the service quit:

And another one that could be unrelated to P2P -- I'm not sure what
was happening at this point:
