Re: ELM327 Bluetooth OBD-II Wireless Transceiver Dongle $57 (including shipping and T
 

From what I read Carman does not support more BlueTooth devices than the ElmScan although these could be added relatively easily.

Your BlueTooth...

My point is about BlueTooth 2.0 cryptography (using linear feedback shift register), and BlueTooth tracking in general (lack of hidden mode / temporary visible).

10 - 30 meters is for BlueTooth 1.2. This encryption scheme is easily crackable. For BlueTooth 2.0 its 100 meters, and crackable in theory.

-1 straw man.

Just because you don't care about a problem doesn't mean it doesn't exist.

I believe the choice between BlueTooth 1.2 and 2.0 is in this case a conscious, important choice.

Now stop stalking me. Creep.

I don't think the range is specific to a Bluetooth version. The class of the device specifies the range : (if memory serves) Class I is 100 m and Class II is 10 m.

You are not being stalked. I have an interest in Carman Bluetooth. You said a a couple dumb things in this thread (and then tried to justify them as not dumb).

Stop being paranoid, you are not being stalked. Stop calling me names.

Remember that a high gain antenna may permit connection or tracking from a distance much farther than specified by the bluetooth spec.

I'm not so much worried about the privacy of bluetooth as I am upset over the high cost of bluetooth to serial adapters. Most bluetooth obd interfaces cost $150 or more. This is at least $50 more than most usb and serial interfaces from the same vendors.

I'd really like carman to support usb so I could build one of these for only $50: http://obddiag.net/products.html

OBDPros has one and its field upgradeable. I'll have mine shortly so I should be able to give details.

Carman should be easily adaptable to use USB (if the serial port driver is sane)

being hidden doesn't stop a determined attacker, it's possible to do a brute force scan of bluetooth devices WITHOUT needing to scan every possible mac. go google for Adam Laurie's bluetooth hacking tools.

Received the one from UK for ~30 GBP. Works great! Had to search for the OBD-II interface (was not in my manual), but it was actually on a straightforward spot. Just hidden. If the car is off, I can actually connect, but then it disconnects right away. Now I'll combine this with my GPS.

What vendor did you order it from?

I guess this one:

Yes.

I think Carman just reads the data from an input device. So if you select a different /dev it should work (if protocol is also same).

Here are 2 other open source utilities for OBD-II

I'm trying to find Carman option to have the raw/extended data but it seems this is gone from 0.7.
