Hello Gabriel,
there is a lot of noise because you are also generating traffic on the network.
However I can see the ICMP Echo Request and then an Echo Reply, therefore the
two nodes seem to be exchanging ICMP packets correctly.

I'm checking again to try to understand what went wrong.

Meanwhile, can you please report the output of
"batctl l"
during a bw test after having set the bw_meter log level by running
"batctl ll bwm" ?

To get the exact log of one test, you can first run batctl l (this will print
all the past log), then you run the test and then you run batctl l again to
obtain the interesting log. Please upload it on pastebin too.

Thanks a lot!
