Hi all, I have to create a Mesh Ad-Hoc Wireless Network using a certain number of Raspberry Pi Zero. I have decided to use Pi Zero Wireless card in ad-hoc mode and use the batman-adv module to create the mesh over the ad-hoc wireless network. Here my systems: - Raspberries Pi Zero W V1.1. - Raspbian Buster: 2021-03-04-raspios-buster-armhf-lite.img - Kernel: 5.10.17+ - Batman-adv: built-in kernel module. No problems to create the ad-hoc wireless network between the Zeroes, even if the mtu needed for Batman-adv complains: [quote]# ip link set dev wlan0 mtu 1532 Error: mtu greater than device maximum[/quote]

Problems arise when I try to add the wlan0 interface to batman handler (the batman-adv module is loaded correctly with modprobe or at boot time)

batctl if add wlan0 <--- OK No Problems

but if I want to request the wlan0 status I receive

[quote]batctl if wlan0: <error reading status> [/quote]

Anyone experienced the same issues?
