I think in this case it would help to first make sure that you're able to successfully get the raw bytes from one side to the other over UDP (i.e. log the byte arrays on the sending side and receiving side and make sure they are the same length and are identical). This seems like the part that is most likely to be the problem. Once you're able to get the raw bytes across successfully, parsing the proto should be fairly easy.
