I want to access for CC6 by Wifi (PC or Android-Tablet).

Thanks for information.
I can access CC6 and check by Web browser (Picture of Digi).

So, Is Network bridge need to Wireless access ?

I think to “wlan0 + iwconfig” can setup.

But, iwconfig does not set “Master mode”.

And I append “hostapd” package.

“hostapd” can setup wlan0 to “Master mode”.

PC can search CC6-AP, but it does not success the “ping”.

yes, you need to follow this document to configure cc6 as Access point
