payload data doesn't matter so you don't need my dumps, maybe you are
using the same address on both sides of the link or you are sending to
the wrong address or the route isn't set up correctly
I'm attaching a test program that works with my phone but this is only
the host part because I don't know how to set up the device part, can
you share the details of your setup?
According to Documentation/networking/phonet.txt it should be possible
to do both parts on the same machine, that would test only the phonet
module and not cdc_phonet ("Each socket [...] can send and receive
packets with any other peer").
