Dear all, Thanks for making such a great project!
I'm following the guide from https://github.com/binnes/WiFiMeshRaspberryPi, and setting up wifi mesh network on top of raspberry pi 3B+. Below steps are good now: - batctl ping works (peer can ping each other through both IP and MAC address) - mac os wifi client can discover the ad-host network, and join the network But, after joining the wifi network, the client can not get DHCP, and I did below debugging 1. configure static IP in the same subnet at the mac OS wifi client manually, and unable to ping other nodes 2. I run "batctl td bat0" to dump packets, and I am unable to see packets from wifi client MAC address 3. I run "batctl td wlan0" to dump packets, and I can see dhcp request, but unable to see further packets $ sudo batctl td -p 256 wlan0 09:01:23.945726 IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from 18:65:90:d1:cf:79, length 300 09:01:26.457608 IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from 18:65:90:d1:cf:79, length 300 09:01:30.999474 IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from 18:65:90:d1:cf:79, length 300 09:01:39.903231 IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from 18:65:90:d1:cf:79, length 300 4. I follow the document https://www.kernel.org/doc/Documentation/networking/batman-adv.txt, but seems like unable to see batman related files/folders under /sys/class/net/wlan0. Here is output: $ ls /sys/class/net/wlan0 addr_assign_type carrier device duplex ifindex mtu operstate phys_switch_id speed tx_queue_len wireless address carrier_changes dev_id flags iflink name_assign_type phy80211 power statistics type addr_len carrier_down_count dev_port gro_flush_timeout link_mode napi_defer_hard_irqs phys_port_id proto_down subsystem uevent broadcast carrier_up_count dormant ifalias master netdev_group phys_port_name queues testing upper_bat0 I searched from google, and seems all documents only mentioned about setting up bat0 interfaces, but not one like me. So wonder to know if anyone here can share insight on how to debug it.
