I wonder if anyone can tell me if there is bluetooth module, cost less than $10.
I need to make a wireless logic signal (low/high) send/receive pairs with communication range less than 30 meters. Multiple of those modules will be used simultaneously within a multi level building. Therefore modules must be able to create pair-wise connections and should not be interfered by other pairs. That is why I think bluetooth module would be good. If possible, I would prefer a bluetooth module with capable operating without external microprocessor.
Can you advise me any low-cost solution for the above mentioned application?

I've bought from these people before and had good service.
