Is it possible to listen to Blue Tooth with a scanner? Or is Blue Tooth encrypted, i think its around 2.4ghz so i know the unidens wont do it but i guess AOR radio may?

Blue tooth has an effective range of arms length (10 Meters actually) Basically anything you could listen to, you would have to be so close you would hear their voice without the scanner.
From a google search
"Bluetooth is extremely secure in that it employs several layers of data encryption and user authentication measures. Bluetooth devices use a combination of the Personal Identification Number (PIN) and a Bluetooth address to identify other Bluetooth devices. Data encryption (i.e., 128-bit) can be used to further enhance the degree of Bluetooth security. The transmission scheme (FHSS) provides another level of security in itself. Instead of transmitting over one frequency within the 2.4 GHz band, Bluetooth radios use a fast frequency-hopping spread spectrum (FHSS) technique, allowing only synchronized receivers to access the transmitted data."

k thanks LordJ for the reply, didn't think it was possible...

What is Blue Tooth use for?
Okay is it some Wifi?

The biggest use for Bluetooth is for wireless headsets on wireless phones.nec208 said:
Since it is a digital system, it can also be used for sending files (mainly photos) from phone to phone and phone to printer.
I have also seen Bluetooth wireless stereo headsets and Bluetooth set up as a wireless headset system for two-way radios of various types.
There is also a peer-to-peer mode which is pretty good for things like communications between people on a motorcycle.
While it does share some characteristics with 802.11g, it is quite a bit different.

You could make Blue Tooth speakers too!
They work really well, I'm fairly impressed.

Don, good short answer.
Oh wait, I forgot, you have me on ignore, so this is for people who would rather learn then stay in there own little world, protected from knowledge.:lol:
Bluetooth is a short rage (3 power levels; 1 meter, 10 meter, and 100 meter) digital radio protocol implemented at 2.4 GHz. (The fact it uses 2.4 GHz is about its only similarity with WiFi, but that is enough for Don, I guess)
It is intended to replace local cable connections for audio, (Headset, and handset) as well as data (network connections, mouse/keyboard), and peer-to-peer (synchronization).
Probably the biggest difference between Bluetooth and most other short range protocols is that it defines both the link and application layers so devices can inter operate without relying on independent vendors directly working together on the solution, or relying on the user to adopt common higher layer protocols.

Real short answer...
It uses spread spectrum modulation so no, your AOR or other regular fixed frequency receiver will not demodulate it to something that you can understand.

802.11g is a spread spectrum system.
Bluetooth is a frequency hopping system.
I suppose it is possible that there might be a Bluetooth unit with some sort of maintenance mode that would let you monitor. It is also possible that a sufficiently competent hacker could reprogam a unit into a monitor. I have never heard of either of these things happening.
There must be test gear for Bluetooth, although I would guess we are talking about something north of 10K for a unit that would not really be all that interesting to listen to.

I guess Don did not see my link, because he knows so much that he cannot possibly learn anything from others.
Maybe he should check out Bluetooth.org and Bluetooth.com
Can someone quote my post (since he has me on ignore) before he hurts himself
Why would someone care to monitor Bluetooth anyway? Is the guy next to you on the bus so interesting that you need to listen to his phone calls?

Curiosity would be 1 reason,not all people use bluetooth for cell phones,well I don't anyway.I use mine on my scanner.

Do you not need a base? Like you have radio and I have a radio and we can talk if you have a bluetooth base?
Or if I have bluetooth phone and bluetooth base I can send photos from phone to phone if I have bluetooth base and both phones are bluetooth .
N_Jay and others, this thread is about Bluetooth.
If you have something to add that's Bluetooth related, please do so.
If not, then don't post.
Pretty simple.

I have seen ads for Bluetooth units that can run in a peer-to-peer mode. It looks like not all Bluetooth headsets have that mode. The ads mention nothing of a base.nec208 said:
Back when I worked for the shack, we would play with the phones during slow periods. You can send pictures phone-to-phone and the receiving phone has the option of refusing the picture.
I did some reading about Bluetooth back then and found that there is quite a bit to the system that we are not seeing on the market. It would not surprise me to find out there is more to it by now.

A simple Google search for "Bluetooth Sniper rifle" will give you lots of fun stuff. Been around for years but i guess they are much stronger these days.

Sent via a bluetooth link to my phone using the Bluetooth DUN profile.

The couple of links I came up with did not go into details about the software the computer is supposed to be running. In fact, I could not come up with anything beyond the mechanical construction of the "rifle."warrior420 said:
