I would like to pair an off-the-shelf Bluetooth earbud with built-in microphone so that I can have my spoken voice transmitted to a Bluetooth receiver on a robot whereby my voice is amplified by a simple D-amplifier which drives a small speaker. I thought that I could simply pair a Bluetooth earbud to an off-the-shelf Bluetooth speaker, but according to various manufacturers of the Bluetooth speakers, this would not work for transmitting voice. Any ideas on how this can be accomplished is appreciated. Will any of the Sparkfun boards relatively easily accomplish this?
