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

[contact <contact@wifibot.com>]

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
