From: David Chapman on 6 May 2010 11:48 Does anyone in this NG know of any company that markets a fairly small short-range radio-microphone using Bluetooth technology? I'm fully aware of the two-way Bluetooth hands-free mobile ear-hangers but, since they all have the ability to receive as well as transmit, they are somewhat overcomplicated for my purpose. I'd like a very small basic speech transmitter capable of sending one-way speech using Bluetooth over a distance of no more than 5-10 meters, and a suitable receiving arrangement to go with it, of course. Ideally the transmission system should have some level of speech security (frequency hopping ?) to protect against monitoring by any other Bluetooth equipped user. If I can't find any suitable product that already exists, my Plan B will probably be to build one using off-the-shelf Bluetooth modules. Does anyone have any suggestions/recommendations regarding the best modules to use for this application?
