Hi I am trying to setup wfb-ng on my rpi0_2.

To get it working I need to put wifi interface into monitor mode.

I have managed to build custom driver for Wi-Fi card and get it working and showing up as wlan1.

iex(3)> ifconfig
lo: flags=[:up, :loopback, :running]
    inet 127.0.0.1  netmask 255.0.0.0
    inet ::1  netmask ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff
    hwaddr 00:00:00:00:00:00

wlan0: flags=[:up, :broadcast, :running, :multicast]
    inet 192.168.178.141  netmask 255.255.255.0  broadcast 192.168.178.255
    inet 2a02:8108:96c0:5a77:e65f:1ff:fe45:e52  netmask ffff:ffff:ffff:ffff::
    inet fe80::e65f:1ff:fe45:e52  netmask ffff:ffff:ffff:ffff::
    hwaddr e4:5f:01:45:0e:52

wlan1: flags=[:broadcast, :multicast]
    hwaddr 1c:a7:70:77:f2:76

Usual next steps are on standard linux systems is putting interface in unmanaged state. Currently iw on my nerves config says it’s managed.

iex(4)> cmd("iw dev wlan1 info")
Interface wlan1
	ifindex 3
	wdev 0x100000001
	addr 1c:a7:70:77:f2:76
	type managed
	wiphy 1
	txpower 18.00 dBm

I am using following VintageNet config:

config :vintage_net,
  regulatory_domain: "DE",
  config: [
    {"usb0", %{type: VintageNetDirect}},
    {"eth0",
     %{
       type: VintageNetEthernet,
       ipv4: %{method: :dhcp}
     }},
    {"wlan0",
     %{
       type: VintageNetWiFi,
       vintage_net_wifi: %{networks: [network]},
       ipv4: %{method: :dhcp}
     }},
    {"wlan1", type: VintageNet.Technology.Null}
  ]

Next step would involve running following commands as root to set interface into monitor mode:

ip link set <interface> down
iw dev <interface> set monitor otherbss
ip link set <intreface up

I cannot run all of that commands. Reason might be that inferface is still managed or that I am not allowed because of some linux rules setup for the shell. They return following:

iex(9)> cmd("ip link set wlan1 up")
ip: SIOCSIFFLAGS: Operation not permitted
2
iex(10)> cmd("ip link set wlan1 down")
0
iex(11)> cmd("iw dev wlan1 set monitor otherbss")
command failed: Operation not permitted (-1)
255
iex(12)> cmd("ip link set wlan1 up")
ip: SIOCSIFFLAGS: Operation not permitted
2
iex(13)>
