OK.
However, looking at the api, the
assumption is that bss is started by a different
api and the 'enableResponder' api is used for enabling rtt for a given
duration.
It looks like. Note that there's also *disable*, which we hadn't even
implemented before.
The reason we have added enabling ftm responder through start ap is
that
this can reflect beacon IE change in the
configuration in the same place.
Which makes sense, yeah.
In case of the separate command,
enabling responder will not update the beacon,
however, the application must issue the new command, whenever its
updating beacon template.
Right. However, I guess we could allow updating/changing this setting
on
the fly through nl80211_set_beacon() which already allows changing
other
non-beacon parameters (like the probe or assoc response templates), and
then we can use your approach. Basically changing "SET_BEACON" to be a
bit like "CHANGE_AP".
Agree. ( ftm_responder param will have to be added in
cfg80211_beacon_data
instead of cfg80211_ap_settings)
In that case we definitely would need the
attribute to be 0/1 as you had it so that it not present can be used to
indicate "no change".
OK.
