I have installed batman-adv in 3 ubuntu machine with same essid and cell id. 2 out of 3 are able to discover each other and creating mesh network but the 3rd one is not able to discover.
difference here is, 2 working machine has batman-adv version 2016.3 where as 3rd machine has version batman-adv 2016.5
Is this the reason for the 3rd node to not able to discover in the network? Can anyone tell me how to install a specific batman-adv version?

i found the kernel version in my 3 ubuntu machines were different. 2 out of 3 had version 4.8.0-36 and the 3rd one had 4.10.0. looks like, batman-adv version 2016.5 and kernel version 4.10.0 are not compatible with each other. I was also not able to install 2016.3 version in kernel version 4.10.0.
Solution that I chose was, to downgrade the kernel version to 4.8.0-36 and make sure all the PCs has same kernel version. Installed batman-adv and batctl version of 2016.3 from following link:
once the kernel and batman version of all 3 PCs are same, they are able to discover and create mesh between each other.
