[B.A.T.M.A.N.] batman-adv: node socket communication

This is Muye, I am a university student. Currently, we have a mesh network project using B.A.T.M.A.N.

We are trying to establish wireless communication between each B.A.T.M.A.N client so that they can share information through the mesh network. Specifically, we want to write an application on top of the B.A.T.M.A.N using socket in order to transmit the data packet from one B.A.T.M.A.N client to other B.A.T.M.A.N client. For example, unicast or multicast.

Would you please give us some advices on how to write such application. I have looked at the batctl ping and tcpdump source code, but I was not able to send data packet using the similar mechanism.

We greatly appreciate any of your suggestions.
