Hi Petr,
Re-adding the mailing list to the conversation :)
Didn't quote your previous email as I may have a more fundamental issue.
So, I have checked my WiFi card via the command here:
https://github.com/albfan/miraclecast/blob/master/res/miracle-utils.sh#L112
it seems to not support P2P mode nor commands.
Are those required for connecting to a Miracast device?
I believed that as long as the card understand the packages it should
work and the card seems
to have support for RX / TX of P2P-client, P2P-go and P2P-device frames.
It mentions also the command "start_p2p_device" as supported.
Bests,
/ Giovanni
