Oddly neither of those is correct! The actual hex should be: 08-03-1A-06-08-01-10-63-18-01
which is the first version minus some trailing data. The second version is not valid at all - it isn't just missing data: it is an incomplete and invalid payload. Unfortunately I'm not familiar enough with the C++ API to advise on whether you're using the wrong method vs this being a bug.
