New Post: Sample for sending V3 Traps

I seem to have cracked it.

I checked through the code that decides whether to send an authorisationError response and noticed this line:

            if (parameters.EngineId != Group.EngineId)
            {
                // not from this engine.
                return false;
            }

And then noticed that the Engine ID is hard coded within the library!

        // TODO: make engine ID configurable from outside and unique.
        private readonly OctetString _engineId =
            new OctetString(new byte[] { 128, 0, 31, 136, 128, 233, 99, 0, 0, 214, 31, 244 });

So after tweaking my Trap message by copying the OctetString construction from above to the engineId parameter, it all started to work! Hurrah!
