I`m working on a academic develop project for improve the networks in
rural areas in Peru. We are doing some test with 6 Nanostation M5 for
create a mesh network.
I tried Commotion software with OLSR and all was Ok. Now, we are
testing BATMAN, with OpenWRT and batman-adv module, but I have some
I have compiled OpenWrt Backfire r32751 (Load: 0.09 0.10 0.05) and
installed batman-adv with opkg following this
Why are you installing it with opkg? This sounds a little bit like you try to
load a kernel module that wasn't compiled for the kernel that is running on
the machine (which would be extreme bad when there are ABI differences). Also
this "pizza" link you showed at the bottom of the mail gives the impression
that you may have done something like that.
The best way is to include it in your image.
When I put:
lsmod | grep batman
batman_adv 67936 0
and seems to be load in the kernel
But when I try to add the interface wlan0 for activate batman in it,
the Nanostation remains locked and i need to reboot.
I have tried this with:
echo bat0 > /sys/class/net/wlan0/batman_adv/mesh_iface
batctl if add wlan0
with the same bad result.
What am i doing wrong?
Hard to tell with the information we got here. Are you using the serial console
on your device? Does it print a backtrace (can you create a backtrace with
symbol tables enabled)? Are you sure that the kernel and batman-adv module are
100% binary compatible? What version of batman-adv is it? Did you try the
newest openwrt devel package from
(i think the package is
I have noticed that i have not the bat0 interface
created,is it normal?
Do i need create another aditional interface like ath0?
bat0 (or any other name you choose for your batman-adv device(s)) are created
after you attach an interface to it (this is what you are doing when you say
that your node "freezes").
Uh, please don't use this one. It is outdated as hell and has nearly nothing
to do with the stuff you are using (or at least should use).
Do you recomend me to change to batmand instead?
Just to give an impression:
Latest release of batmand:
Latest release of batman-adv
Commits in batmand in the last 6 months (master branch): 0
Commits in batman-adv in the last 6 months (master branch): ~250 (and this does
not include all the stuff that happens before a change is accepted)
Of course, this can also be a sign of perfection. But I can say for sure that
the most development in the last two years happened in batman-adv and not in
Do you know if there is any BATMAN implementation
for a mesh network
of Nanostation M5, easier to install and manipulate?
Um, even easier? At least I find it extreme easy to get it running:
$ modprobe batman-adv
$ batctl -m bat4 interface add eth0
$ ip addr add 192.168.3.11/24 dev bat4
$ ip link set dev bat4 up
$ batctl -m bat4 originators
And only step 1 and 2 are batman-adv relevant. The rest is just to configure the
usual stuff and step 5 to check for detected originators. And "-m bat4" is
optional. I just wanted to call my device bat4. Please let me know how this can
be made easier without restricting users.
And why are you refering to a specific product? I thought that you just use
Yep, now that everybody has confused the hell out of you,,, try
flashing the unit with
setup to get internet access. and correct wireless settings
opkg update | opkg install kmod-batman-adv | enable with
edit /config/batman-adv to reflect wlan0
reboot Done | check with batctl o
Couldn't be simpler, no need to compile anything.
