Re: wifi ad-hoc

Yes, it is possible.

I'm using ubilinux (Debian).

I edited /etc/network/interface, and entered the following for wlan0:

auto wlan0

iface wlan0 inet static

    address 192.168.42.1

    netmask 255.255.255.0

    wireless-essid edison

    wireless-mode ad-hoc

Note that /etc/network/interfaces is not available in Yocto, so I'm not sure how you'd do it there, but it should be possible, although I hate saying "it should be possible" without actually testing it.

Once the above is in /etc/network/interface, I did "ifup wlan0"

and I could then use 'iwconfig' to confirm that the Edison was indeed in ad-hoc mode, I could see

root@ubilinux:~# iwconfig  

wlan0 IEEE 802.11abgn  ESSID:"edison"

     Mode:Ad-Hoc  Frequency:2.412 GHz  Cell: Not-Associated

     Tx-Power=31 dBm

     Retry  long limit:7   RTS thr:off   Fragment thr:off

     Encryption key:off

     Power Management:on

And I could then connect to it with my iPhone. I didn't have time to pass traffic, but I think that demonstrates it can be done.

Rgds,

Dave.
