Batman mesh bridged Issue

[REMY]

Hello

I have install openwrt on three devices with snapshot commit f07fe36f22fcf3f3da4e0440dfc5c39516e2cb55 .I have installed kmod-batman-adv and wpad-mesh-wolfssl.
it's working fine but i have some latencies and some instabilities.

I try to install the latest snapshot d49f1acff1a79992c474fceaeac066671f838a2c.
There is no traffic between batman interfaces.

Thanks for your help

When starting out with meshes it is simplest to put the bat interface into the existing br-lan rather than make more networks. The nodes will be basically "dumb APs" but connected by mesh instead of by cables. Turning on stp allows you to also connect by cable for testing without having a problem with a loop.

Don't have more than one network in the option network option in /etc/config/wireless. Setting 'LAN_INTERNE' is sufficient since the network config defines it as the bridge master of bat0.1

And of course when something "doesn't work", check your log file for relevant errors. Additional useful diagnostics are batctl n (requires batctl-full) and iwinfo <mesh radio interface> assoclist.
