Hi,

Starting to play around with the FTM/ToF support in iwlwifi, but 
documentation is (understandably) scarce at this point. Using a pair of 
8260:s I had lying around.

Can someone give me some hints on how to work the debugfs API for a 
successful measurement?

I've set up one card as AP with hostapd (with ftm_responder=1 and 
ftm_initiator=1 in hostapd.conf), the other as a STA.

 From the STA, I've played with 'tof_range_request' in debugfs. Writing 
send_range_request=1, which it doesn't choke on or anything, but nothing 
seems to happen. Guess I need to set things up a bit first, but how?

If it's possible to get this to work at all at this stage, some hints on 
how to do it would be great.


Thanks,
Joel
