Re: [Discuss-gnuradio] gr-ieee 802.11 and integration with linux stack (wpa_supplicant)

[Manolis Surligas]

Hi all,

we have done it two years ago as part of my master thesis and it works like a charm! The SDR IEEE 802.11 implementation can be configured as AP using hostapd or adhoc via the network manager. We had some problems making it work as a normal client however.

Our approach has a kernel module that provides an interface for receiving and sending PDUs from/to SDR PHY. Internally, the kernel module communicates with the mac80211 for passing around these PDUs.

I guess no, but since it doesn’t have a standard compliant MAC layer that might be of limited benefit.

If you really want to look into integrating it in Linux, I would implement it as virtual WiFi device, similar to hwsim (https://wireless.wiki.kernel.org/en/users/drivers/mac80211_hwsim). Then the higher layer stuff like hostap and wpa_supplicant would just work out of the box.

Best,

Bastian
