Missing P2P support #173

Open MrMEEE opened 7 years ago

MrMEEE commented 7 years ago

Hi..

Following the Readme I get:

mj@falcon ~/Hentede filer/wds-master/connman/usr/sbin $ sudo ./connmanctl connmanctl> enable wifi Enabled wifi connmanctl> enable p2p Error p2p: Method "SetProperty" with signature "sv" on interface "net.connman.Technology" doesn't exist

connmanctl>

Info:

Any ideas???

Enabled wifi
connmanctl> enable p2p
Error p2p: Method "SetProperty" with signature "sv" on interface "net.connman.Technology" doesn't exist

There's a bug in connmanctl that makes this error message weird: what I think it's trying to say is that technology 'p2p' does not exist -- connman thinks there's no support for Wifi-P2P. What should happen is that after "enable wifi" a new technology with path /net/connman/technology/p2p is created, you can check that with "technologies" in connmanctl.

You might get better help from connman folks, my expertise is pretty limited...

I did do a quick check on a build with connman 1.33, supplicant 2.6 on a NUC with intel 8260 wifi : "enable p2p" works fine.

MrMEEE commented 7 years ago

Ok.. I got a step further... after compiling supplicant 2.6 from source, I was able to enable p2p...

Now I can scan and detect my device:

connmanctl> scan p2p connmanctl> peers DOOGEE_P1_BOkJ70 idle peer_185e0f6a2700_e276d08f5479 Scan completed for p2p connmanctl> agent on Agent registered

I can the run the test script:

mj@falcon ~/Hentede filer/wds-master/desktop_source $ sudo ./desktop-source-test

I then get: Agent RequestPeerAuthorization peer_185e0f6a2700_e276d08f5479 WPS = [ Type=wpspin, Requirement=mandatory ] Scan completed for p2p WPS PIN (empty line for pushbutton)?

in connmanctl...

if I just press enter, the screen turns black on the projector... and nothing happens...

after some time I get:

Agent ReportPeerError peer_185e0f6a2700_e276d08f5479 connect-failed connmanctl> Retry (yes/no)?

Any ideas???

When I press enter I get:

What is your sink device? another machine running WDS sink-test or some actual product?

In any case, screen going black (and the connection from 192.168.49.1) suggests the Wifi-p2p part is now succeeding (you mentioned an error message but I'm guessing that was a different test). You should look at the miracast (RTSP) negotiation and any debug output next: I admit I no longer remember how to enable the debug output... "G_MESSAGES_DEBUG=rtsp" might get you the network messages.

MrMEEE commented 7 years ago

I'm trying to connect to a mini-projector (Doogee P1)...

G_MESSAGES_DEBUG=all sudo ./desktop-source-test

Nothing??

MrMEEE commented 7 years ago

Ok..

./desktop-source-test --gst-debug-level=9

gives alot of info.. can't really find any errors....

Logfile is available here: http://martin-juhl.dk/wds/log.txt.gz

MrMEEE commented 7 years ago

@jku Any ideas??

MrMEEE commented 7 years ago

One thought is that it might be the wrong resolution for the stream that causes the problem... the projector only supports upto 840x400...

Any way to change the format of the stream???

varun-dhar commented 4 years ago

I am also having this problem enabling p2p from connmanctl, any solution?
