[ADD] Link: 3
[miraclectl] # run 3
now running on link 3
[ADD] Peer: 3a:aa:3c:c2:75:a7@3

i open my android phone to "screen mirroring" fun, and it cannot find any available devices. but miracle-sinkctl can find the peer of the phone. Do I need set something for wpa_supplicant?

If miracle-sinkctl find a peer everything seems to work on

I think the problem is my wifi usb device. So i try to connect the ubuntu to my android phone by p2p_connect, and get go neg fail. My wifi usb device is rtl8192eu, so i use the rtl-wpa_supplicant which is modify by rtl. Then the go neg is success, but i get CTRL-EVENT-EAP-FAILURE...... Maybe it is not a problem. This is my p2p-connect log. wpa_supplicant.log

Just can recommend to try several times. It is known that Miracast handshaking just fails sometimes. Switching on/off WiFi on both devices could help before try again

All seems correct. Maybe the problem would be seen in journalctl.log. What's your environment (OS and version)

Further checks you can do:

• Check if you installed all the needed gstreamer plugins with

https://github.com/albfan/miraclecast/blob/master/res/test-viewer.sh

After that something like

gst-launch-1.0 -v videotestsrc pattern=snow ! video/x-raw,width=1280,height=720 ! autovideosink

should work.

• Check if this problem is related with X11 or Wayland

echo $XDG_SESSION_TYPE 
wayland

if you're under wayland https://github.com/albfan/miraclecast/issues/183#issuecomment-291012571 should help
