Hi
I am trying to intergrate wifi display (or Miracast ) on imx6Q SDP board. I have used COMFAST WU825N which has a RTL8192CU chipset. I have used the rtl8192cu driver available from Realtek site, and cross complied it on my PC for the ubuntu OS with kernel version 3.0.35 (3.0.35-2666-gbdde708). I have used the wpa_supplicant (2.0, 2.1 and 2.2) in which I have enabled the CONFIG_WFD, CONFIG_P2P, etc. I am running.
./wpa_supplicant -Dnl80211 -c/home/miracast/wpa_supplicant.conf -iwlan1 -ddK
./wpa_cli
when I give the command :
>p2p_listen
OK
Output on wpa_supplicant:
RX ctrl_iface - hexdump_ascii(len=10):

wlan1: P2P: Starting Listen timeout(65,535000) on freq=2462 based on callback
wlan1: P2P: Set timeout (state=LISTEN_ONLY): 65.555000 sec
But I am not able to detect it on nexus 4 and 5 phone under wifi direct. When I run p2p_find, p2p_peers, p2p_peer MAC-ADDR, I am able to detect the phone but the phone is not able to detect the device. What can be done should I try another device, if so kindly suggest other device names.
Hi
I have encountered the same problem, p2p_find is ok, but p2p_listen is NG, do you have find the solution?
Sincerely
Hello Venkathesh,
I think your Wifi device it is working, so it is more related to the Android Configuration, which I am really not an expert, but you can take a look into this application note made by Silex. Also maybe related to Ubuntu, which version are you using? I think this is not related to the HAL of the Wifi, it is in the middle ware.
