Hi,
I configured sucessfully 802.11s mesh with batman-adv using the guide: https://openwrt.org/docs/guide-user/network/wifi/mesh/batman
The part of important configuration is:
/etc/config/network:
config interface 'lan'
option type 'bridge'
option ifname 'bat0 eth0.1'
config interface 'bat0'
option proto 'batadv'
option routing_algo 'BATMAN_V'
config interface 'net_wifi_mesh0'
option mtu '2304'
option proto 'batadv_hardif'
option master 'bat0'
/etc/config/wireless
config wifi-iface 'meshnet0'
option device 'radio0'
option mode 'mesh'
option mesh_fwding '0'
option ifname 'mesh0'
option network 'net_wifi_mesh0'
And it works well.
But I thought that I can make second mesh on second radio, so I added to configuration:
/etc/config/network:
config interface 'net_wifi_mesh1'
option mtu '2304'
option proto 'batadv_hardif'
option master 'bat0'
/etc/config/wireless
config wifi-iface 'meshnet1'
option device 'radio1'
option mode 'mesh'
option mesh_fwding '0'
option ifname 'mesh1'
option network 'net_wifi_mesh1'
Generally it worked too, but not in the way I wanted
After this change I saw 2 copies of the device in batctl lists: one for the 5GHz (mesh0, MAC1) and the second one for 2.4GHz (mesh1, MAC2). Maybe it is ok... I don't know
I'm expecting in batctl o list such a device, with double mesh networks to be visible as one with two available paths...
Regards,

I did the first test in too much of a hurry
The configuration above works properly.
I have more neighbors (10):

But from a performance perspective, it seems better to make only one mesh on 5GHz and connect the clients to a 2.4GHz radio.
I think topic can be closed.
