Either because the interface is down, not connected or is manipulating the transmitted OGMs (broadcast) in some form. The latter can for example happen if the underlying link is converting broadcasts to unicast - some accesspoints are doing that. I just mention this because you seem to use station interfaces as underlying interface for bat0. You can use tcpdump on the underlying interface to see whether the submitted packets (OGMs) on one side are received exactly the same on the other side. Wireshark has support for batman-adv. So, you could easily check the recorded PCAPs with it. You can also check "batctl n" to see on which side you can correctly "hear" OGM packets. If you can not hear it only on one side then you should check this one initially (but continue with the rest).
