RTL8812au wifi-direct not advertising

[visbs]

Hi,

I am using RTL8812AU based chipset USB Wi-Fi Adapter (Like ASUS AC56 , Linksys WUSB6300) in ubuntu (tried in different OS and Kernel version). And I am trying to make use of WI-Fi Direct using wpa_supplicant (P2P Enabled) with user app wpa_cli. In case of Intel Wireless Driver, whenever I do P2P_FIND or any scan command, from wpa_cli, my device is visible in any Wi-Fi Direct supported devices like Android, Windows etc. But in case of Realtek driver (rtl8812au), my device is not visible or listed in Wi-Fi Direct device list, whereas I can get the nearby peers available in my device. As well I am able to connect to any SSID available. So, am I missing something additional setup required for driver to make my device visible to other peer? Any help would be very helpful? PS: I did go through rtl8723 issue but the changes there didn't help. Thank you,

Hi visbs,

I am using D-LINK DWA-182 on TinkerOS 2.0.8(Debian 9). It can find p2p devices by wpa_cli P2P_FIND.

First, let network manager unmanaged your USB Wi-Fi dongle. Add unmanaged-devices to your /etc/NetworkManager/NetworkManager.conf

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false

[device]
wifi.scan-rand-mac-address=no

[keyfile]
unmanaged-devices=mac:f8:e9:03:da:9c:b1

Then, create /etc/wpa_supplicant/p2p_supplicant.conf with following content.

ctrl_interface=/var/run/wpa_supplicant
update_config=1
device_name=tinkerboard
device_type=1-0050F204-1
p2p_go_intent=15
p2p_go_ht40=1

I assume new interface name is wlan1. You can find P2P devices with below commands.

iwpriv wlan1 p2p_set enable=3
wpa_supplicant -c /etc/wpa_supplicant/p2p_supplicant.conf -i wlan1 &
wpa_cli -i wlan1 p2p_find
wpa_cli -i wlan1 p2p_peers

Thanks, Sam

@Sam2Hsu even using my USB device i can find the peers, but in android devices am not able to see(i.e the driver is not advertising).

Hi Visbs,

My dongle can be searched by android devices after become group owner. I am using TinkerOS_2.0.8. and the same steps with NetworkManager and p2p_supplicant.conf.

Here's the command to be group owner.

iwpriv wlan1 p2p_set enable=3
wpa_supplicant -c /etc/wpa_supplicant/p2p_supplicant.conf -i wlan1 &
wpa_cli -i wlan1 p2p_group_add persistent
wpa_cli -i wlan1 wps_pbc

Dongle can be searched after p2p_group_add, and can be connected after enter wps push button. BTW, p2p device name will be your dongle mac address. Android Wi-Fi Direct page screenshot
