16 did nothing... would still do about 2 reads before I got the answer from the 
first. Knocking it up to 64 did improve things, answers always seem to sync up 
with commands. Not sure if I want to leave it there or not, it's visibly slow. 
On the other hand, I'll only ever be reading signal strength out of the rssi 
register anyway, so I might. Will have to see how much it affects things.

Thanks,
