Alternate Addresses are not handled correctly in sdk3

I am pretty sure this is fixed, I think Mathew's issue is related to connectivity as he mentioned that SDK Dr returned some errors. Note that the patch is merged, so anybody can validate this by pulling master.

See the update from , looks like the same issue? There's not enough info in the logging here though to say.

I applied the patch, and I'm now getting a different exception:
