How many of those can you use simultaneously?
What do you use as master?

How has anyone managed to relate this datasheet to the thing sold by DX?


I had a look recently for similar but higher quality products. The usual
contenders (element14, mouser, digikey) sell these for about $30-50+GST:
Panasonic PAN1321, Laird BTM411, Roving Networks RN-42 (or RN-41 for
class 1 power). All come with a proper datasheet and CE + FCC approvals
and do SPP. Some do bluetooth 2.1 (better encryption).
