Gl-ar750s / batman

I would like to add mesh nodes using batman-adv to my existing openwrt 21.02 setup. I don't know what version of openwrt comes installed on the gl-ar750s, but can I upgrade the gl-ar750s to openwrt 21.02 and install batman-adv?

Thanks.

there's a kmod-batman-adv for your arch - https://downloads.openwrt.org/releases/21.02.0/targets/ath79/nand/packages/

but you need to check if there's a batmand too, might not be required though, I'm still on 19.07.
