BBB WiFi Client/AP Switcher

These two scripts switch the mode of the WiFi adapter:

• /usr/local/sbin/wifiModeAP
• /usr/local/sbin/wifiModeClient

You'll also need 'hostapd' installed, along with 'udhcpd'. The following files are the various configuration files necessary for the above to scripts to work.

• /etc/network/interfaces.ap
• /etc/network/interfaces.client
• /etc/hostapd/hostapd.conf
• /etc/default/hostapd
• /etc/udhcpd.conf
• /etc/default/udhcpd
• /etc/wpa supplicant/wpa supplicant.conf

And if you want to route traffic between the wireless and wired interfaces, you'll also need:

• /usr/local/sbin/setiptables

The idea is that the /etc/rc.local script will check the state of a switch at startup, and run the appropriate script to set that mode. At the moment, I'm forcing /usr/local/sbin/wifiModeAP to run in /etc/rc.local until the hardware is finished.

See BBB WiFi Monitor for a script that monitors for IP address changes on all interfaces, and outputs the new configuration to a printer.
