I’m not really sure if I get what you are trying to do, but you will receive 
PDUs from the MAC block so you can not just connect a file sink.
The example pipes the PDUs to a socket and you can listen to that socket with 
netcat and pipe the output to a file with something like

nc -u localhost 52001 > foo.txt

I guess this is what you want.

Best,
