Each pair of R-6 smartglasses WiFi has a unique, randomly generated MAC address by default.
To view from Android GUI go to --> Settings -> Wireless & Network -> Wi-Fi settings, then press the menu button, and select Advanced.
From your console, the ifconfig command will show the MAC address & state of the interface when the R-6 smartglasses have WiFi enabled.
tiwlan0 Link encap:Ethernet HWaddr 00:67:FC:60:F8:E2
If a specific MAC address needs to be set on the R-6 smartglasses edit the file: /mnt/config/system.prop
and add the MAC address following the "emac.id=" on a line by itself.
After this file is changed you will need to reboot the device twice (x2) before the MAC address is updated.
