I have an Android phone. I have a Bluetooth loudspeaker and I can use that to play music etc from the phone. I also have a Bluetooth hands free headset and I can use that to make calls without speaking directly into the phone.
So can I link all that up and use the phone as a hands-free megaphone? I'd like to be able to speak into the headset and have my voice come out of the loudspeaker. If it's possible, how do I do it?
(Why? I'm a rower and I want to find an easy way for the person giving the instructions to the crew to get his/her voice heard. If you're in a coxed boat, it's easy - the boat is wired with loudspeakers under each seat or under every other seat, and the cox has an audio box and a headset to speak into, which plugs into the boat's wiring. But in a coxless boat, typically a coxless four at our club, the person in the bow seat has to steer and give the commands as well as rowing, and there's no technological support. When you're going fast, or when you're passing a motorised craft, it can be very difficult for the cox to make him/herself heard. Ironically the person who is most likely to not be able to hear the commands is the stoke, furthest away at the other end of the boat, who is the one person who really needs to hear the commands as all the others take their cues from the stroke.)
