That script make some assumptions about where to find your network interface and its name

run with

$ test_hardware_capabilities_DEBUG=10 ./test-hardware-capabilities.sh

Seems it finds you have an wlan interface in /sys/class/net/wlan0but this command is failing:

$ iw dev wlan0 info

check you have iw installed and paste here output for:

$ iw dev
$ iw phy

NOTE: Remember to put output into three ` at beginning and at the end

[visbs]

visbs@visbs-Vostro-260:~$ iw dev
visbs@visbs-Vostro-260:~$ iw phy

didn't give any output

but iw is installed  as it shows 
$sudo apt-get install iw
Reading package lists... Done
Building dependency tree       
Reading state information... Done
iw is already the newest version (4.14-0.1).

[albfan]

I think you could need to install more packages to make it work. See https://superuser.com/q/1049960

I can add a check about this problem to be sure is is working.

Anyway this is only a check. If you suppose your dongle supports WiFi direct just try with miraclecast

[visbs]

i did try that mentioned in that site but still i am not able to get the hardware-capability , why i need to see this badly is that i am not able to go further after

visbs@visbs-Vostro-260:~/miraclecast$ systemctl stop NetworkManager.service 
visbs@visbs-Vostro-260:~/miraclecast$ systemctl stop wpa_supplicant.service

[miraclectl] #

so as i have followed all the steps give in README.md i dono still why am not able to start off....
/ I know that this going off topic but any help would be appreciated

[albfan]

Provide logs for support as said in wiki faq. But see miracle-sinkctl is not working right now. See #4 and #172

[visbs]

logs.zip

[albfan]

You need to run with miracle-wifid and miracle-sinkctl with --log-level trace to see more details on captured logs. Remember to start journalctl -f prior to all them (in other terminal) to catch all the setup miracle-wifid do and the communication when miracle-sinkctl tries to connect

[visbs]

thank u my problem was solved i may need some more assistance regarding the next steps will look into the repository, thanks again @albfan

[albfan]

Would be great to document what was the error, to help others in same situation, the whole idea, is to create know-how with all these issues

Feel free to open more issues with specific errors

[visbs]

1. make distclean
   2.make
   3.sudo make install
   did the trick for me
   now i am able to get the p2p_support msg

visbs@visbs-Vostro-260:~/miraclecast/res$ ./test-hardware-capabilities.sh 
wlan0 supports P2P

thanks for the support

[albfan]

What source code are those commands building?. Is impossible that miraclecast fix iw for you.

You had installed some firmware that make it work

[visbs]

i think after following these steps and a reboot made it possible

I think you could need to install more packages to make it work. See https://superuser.com/q/1049960

[albfan]

Yes, I think so. Anyway have to protect iw from fail there
