AA 06 is indeed 101, that's "varint" encoding. The MSB of each byte is continuation, 7 bits payload, and adjust for endianness. The idea of decode-raw is that it is enough to start guessing at how to reverse engineer a message, for example you can see values that are clearly string IP-addresses. However, the other fields are much harder to interpret without context. If you do have the original .proto schema, it would help tremendously.
