u80211d
a wifi introspection and scanning daemon for OpenWrt.
the following ubus calls are provided:
'wifi' @b95a57e0
"assoclist":{"ifname":"String"}
"scan":{"dump":"Boolean","ifname":"String"}
"cac":{"ifname":"String","channel":"Integer","width":"Integer"}
"reg":{"country":"String"}
"iface":{"phy":"Integer","sta":"Boolean","ap":"Boolean","mon":"Boolean","add":"String","delete":"String"}
assoclist - return a list of stations associated with a BSS
{
"xx:xx:xx:xx:xx:xx": {
"mac": "xx:xx:xx:xx:xx:xx",
"interface": "wlan0",
"signal": 161,
"inactive": 1130,
"rx_pkt": 34,
"tx_pkt": 16,
"rx_rate": {
"bitrate": 288200,
"mhz": 80
},
"tx_rate": {
"bitrate": 12000,
"mhz": 20
},
"rx_bytes": 4836,
"tx_bytes": 2362,
"tx_retries": 45,
"tx_failed": 0
}
}
reg - can be used to get/set the 11D domain
{
"country": "US",
"dfs-region": 1
}
iface - return a list of all local wifi interfaces. it is also possible to
create add/del interfaces using this call
{
"wlan0": {
"mac": "xx:xx:xx:xx:xx:x",
"interface": "wlan0",
"dbm": 30,
"iftype": "ap"
}
}
scan - trigger a site survey. once complete a notification will be broadcast.
upon an event a dump can be read out. automated periodic scanning is
also supported.

}
}
cac - trigger a DFS scan on a specific channel/width. upon completion a event
is broadcast. automated periodic scanning is also supported.
the following events are generated
