Hello,

I'm having a problem with BMX when trying to make a client node connect to a gateway node.

It's BatMan-eXp 0.3-rc1 rv1636 (compatibility version 10).

The following is a detail of the tests performed.

For some time we have been using B.A.T.M.A.N.-Experimental to communicate our nodes, but, in the last revision that we are testing we are experiencing problems when a client node tries to connect to a gateway node which provides Internet access. It's the version that brings OpenWRT Backfire (r21564).

We have been using the version r1157 of BMX and in this version all of our nodes are working fine.

A client node, with version rv1636, never chooses a gateway node.

It has been proved that although there are two nodes with the version rv1636 (a gateway and a client) the client node still doesn't chooses a gateway.

It should be noted also that the nodes can see each other and there is communication between them. It is possible to ping between a node with rv1636 and a node with r1157 without any problem.

The start of the client node it's made with: /usr/sbin/bmxd dev=ath2 -o 2000 -r 1

Am I doing something wrong?

Here it's data from the debug:
