Re: [B.A.T.M.A.N.] no able to switch routing algo to V ?

Thank you, it is working and it is more clear for me.

I have switched to V but when I switch on other V nodes, my first node
reset or freeze, probably a kernel panic. Need to plug a rs232 to be
able to see what could be the problem.
I will switch back to IV.

for info my network file:

config interface 'lan'
option ifname 'eth0 bat0'
option force_link '1'
option type 'bridge'
option proto 'static'
option ipaddr '192.168.204.1'
option netmask '255.255.255.0'
option ip6assign '60'

config interface 'mesh'
option mtu '1532'
option proto 'batadv'
option mesh 'bat0'
option routing_algo 'BATMAN_V'

config interface 'bat'
option ifname 'bat0'
option proto 'static'
option mtu '1532'

and my wireless :

config wifi-device radio0
option type mac80211
option channel 1
option hwmode 11g
option path 'pci0000:00/0000:00:00.0'
option htmode HT20
option txpower 22
option disabled 0

config wifi-iface
option device radio0
option network mesh
option mode adhoc
option ssid mesh
option encryption none
option bssid 02:CA:FE:CA:CA:42
option ifnam adhoc0

Best Regards,

Laurent
