Newer builds of UDOObuntu are supporting the software access-point mode for the WL1831 chip.

In order to enable SoftAP mode, install the udoo-softap metapackage:

sudo apt-get install udoo-softap

Doing this, a default /etc/hostapd/hostapd.conf will be provided. Edit this file to change the access point settings:

interface=wlan0           
driver=nl80211            
hw_mode=g                 
macaddr_acl=0             
auth_algs=1               
ignore_broadcast_ssid=0   
ieee80211n=1              

ssid=UDOO hotspot       
channel=1               
wpa=2                   
wpa_key_mgmt=WPA-PSK    
rsn_pairwise=CCMP       
wpa_passphrase=udooboard

You should change:

  • ssid is the name of the network;
  • channel is the frequency channel (it is better to pick the channel least congested);
  • wpa_passphrase is the password to connect to the network.

In /etc/default/hostapd be sure that DAEMON_CONF is uncommented and pointed to the hostapd.conf path:

DAEMON_CONF="/etc/hostapd/hostapd.conf"

Heads up! When in Soft-AP mode, you cannot connect to wireless networks in client mode! In fact, installing udoo-softap you are disabling the wpa_supplicant service. Uninstall the Soft-AP metapackage to restore client Wi-Fi connectivity.
