Batman-adv On Raspberry Pi Zero

Batman-adv On Raspberry Pi Zero

[giuseppedv]

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?

Make sure you've updated batctl to the most recent version. For example from 
Debian backports. Otherwise batctl might try to read the status information 
from sysfs - which is no longer supported by the newest batman-adv releases.

Kind regards,
