I would like to use three different ch= annels to reduce the interference, like this: > =E3=80=80=E3=80=80[Node A] <- channel 1 -> [Node B] <- channel 2 -> [= Node C] <- channel 3 -> [Node D] > =E3=80=80=E3=80=80First I configure eight wireless cards to the specific = channel in ad-hoc mode using =E2=80=9Ciw dev wlan0 ibss join =E2=80=A6=E2= =80=9D. > =E3=80=80=E3=80=80Then, I think I should add wlan0 and wlan1 to the same = batman-adv interface (that is bat0) in every device. So I need to configure= four nodes with the same commands like: > =E3=80=80=E3=80=80 echo bat0 > /sys/class/net/wlan0/batman_a= dv/mesh_iface > =E3=80=80=E3=80=80 echo bat0 > /sys/class/net/wlan1/batman_a= dv/mesh_iface > =E3=80=80=E3=80=80Last configure an IP address to each bat0. (Node A-10.0= =2E0.1, Node B-10.0.0.2, Node C-10.0.0.3, Node D-10.0.0.4). > =E3=80=80=E3=80=80But it seem Node A can reach Node B and Node C(using pi= ng), but can=E2=80=99t for Node D. > =E3=80=80=E3=80=80 > =E3=80=80=E3=80=80Am I following the right procedure? > =E3=80=80=E3=80=80Sorry for my poor English. Any help would be appreciate= d. The procedure looks right in general. A few questions to debug: * do you use different ESSIDs for the IBSS-networks? ad-hoc devices joinin= g may override the configured channel and select another IBSS-network instead when it has the same ESSID. * have you confirmed that the WiFi connection works without batman-adv? ju= st set up your WiFi, configure different IP addresses and ping for each hop to test. * does the output of "batctl originators" helps you? Are the other nodes d= isplayed on node 4?
