Bluetooth

I don't have much knowledge of bluetooth but was thinking about it the other day, would it be possible to set up 2 headsets to communicate with each other for car comms?

Possibly (you could always phone eachother )...but with the price of bluetooth headsets it would cost just as much (and be much less effort) to just go an buy one of the intercoms bikers use..... IMO

I don't think Bluetooth itself has that great a range - you'd need to be driving pretty close together to get it to work.
The alternative is to use a bluetooth headset attached to a mobile - but you're going to have to ring to talk, plus there's call charges etc.
I think the best bet is to use a radio (like the bike folks) they can be got with a headset that fits under a helmet (if needed), have a range up to a couple of miles, have no call charges and I think you can have more than 2 people on the same freq - kinda like a confwerence call! I haven't used them myself, but I have friends who swear by them. I must get one when I get my own heap road legal.

That's what I assumed you meant. Shouting works for me

yeah for passengers

Apart from everything else, bluetooth eats batteries (this is a problem we've found in my company - leave bluetooth switched on on a mobile phone and your battery lasts half as long as when it's switched off)

Hi

Blue tooth I do not notice any battery problems on my phone or head set and get good battery life. If you have pore battery life on youer phone check to see if the blue tooth is set to ON or discoverable.

As a security not it is not really a problem but nokias and some other makes come with the blue toot enabled by default witch leaves your phone open to blue jacking basically hacking over blue tooth you should be aware of this potential problem

However what I would have assumed that would give you a much bigger problem would be the fact that most blue tooth head sets are implemented in way that requires them to be paired with a master device (usually a phone) and the voice is the passed to the phone and from the phone over the network to another phone. I am not aware of a of the shelf mobile phone head set product that allows two blue tooth head sets to directly communicate with out the phone link. There are a number of rolled blue tooth solutions out there on the web with circuit diagrams but for the hassle if you are not interested in electronics I would recommend the radio option.

Ahh, I assumed you meant for car - car comms. I can't hear much from my passengers above the screaming anyhow.

Er... how would 2 units communicate if the Bluetooth wasn't turned on? It's when the Bluetooth is left on that it drains the battery.

The best solution to the original problem is to look at the communication sets for motorbikes - some of them are quite cheap.

I was looking at the motorbike comms sets recently and for about £150 you can get a system that plugs into your stereo and mobile phone and also comes with 2 headsets/mics designed to go inside helmets........

The one I was looking at was quite clever, it automatically lowered the volume on the stereo when you were talking or on the phone.

I got a bike communications system from maplins for £80. It plugs into a mobile , pmr , cd/mp3 player, comes with 2 sets of stereo headhones and mics ( velcro fittings ) and has a built in fm radio. The only problem is the websit is showing them as discontinued but if you pop into a branch they might have one left as thats how I got mine last month. Catalogue page 18.

It is now reduced to £49.99 - Maplin part number N77BA


DaveFJ - 28/5/04 at 08:05 AM

And discontinued.........


andyps - 28/5/04 at 08:27 AM

I think that is why it is so cheap - there may be a branch with some stock.
