Hi Marek,
thank you for your support!

I have launched the batmand daemon with the command "batmand ath0" and it displays the following message (as usual):

root@MeshBoxA:~# batmand ath0
Interface activated: ath0
Using interface ath0 with address 10.0.0.1 and broadcast address 10.255.255.255

Now, I type the command "batmand -c -d 4":

root@MeshBoxA:~# batmand -c -d 4

But it does not display anything and it does not return.
Moreover, no OGM packets are observed to be travelling using Wireshark.

regards,
Massimo
