Re: Trying to to P2P Device Discovery

[Adrian Chadd]

hi,

i'd love to see initial on-channel p2p support!

doing software-driven off-channel p2p support means we'd need a
channel scheduler in net80211 to switch channels, same as scanning.

(Heck, I'd even just love to see p2p support for iwn/iwm as a starting
point, as they do p2p in firmware.)

So, what are you trying to achieve?

Trying to to P2P Device Discovery

[yu-jui woo]

Hi,

FreeBSD is completely new to me and I'm trying to do Wi-Fi Direct on FreeBSD.

I found that in order to make P2P Discovery (Wi-Fi Direct) work, the
first thing is to make net80211 report probe requests and make the
adapter listen on the Listen Channel for a period.  And I think
sending/receiving action frames will be required later when trying to
make P2P connection.

After some survey, I found that BPF and IEEE80211_IOC_CHANNEL might be
what I'm looking for, but wonder if there's any better way to do this.

Would you give me some advise?

Thanks.
