What encryption methods are supported in ad-hoc mode with ST60/SU60 series radios and how do I enable them?

Answer

The ST60/SU60 modules supports either the open-none or WEP methods in ad hoc mode.

To enable ad hoc mode:

1. Set the interface type as ibss mode and bring it up.

# iw wlan0 set type ibss
# ip link set wlan0 up

2. run wpa_supplicant on all devices connected to the network with the following command:

# wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant_adhoc.conf -D nl80211

To configure open-none:

/etc/wpa_supplicant_adhoc.conf
ctrl_interface=/run/wpa_supplicant GROUP=wheel
ap_scan=2
network={
    ssid="Laird_adhoc"
    mode=1
    frequency=2432
    key_mgmt=NONE
}

To configure WEP:

/etc/wpa_supplicant_adhoc.conf
ctrl_interface=/run/wpa_supplicant GROUP=wheel
ap_scan=2
network={
    ssid="Laird_adhoc"
    mode=1
    frequency=2432
    key_mgmt=NONE
    wep_key0="11111"
   wep_key1="22222"
   wep_key2="33333"
   wep_key3="44444"
    wep_tx_keyidx=0
}
