Hi!

There are some very crude OBD2 adapters now starting to show up with a MAC address of 11:22:33:DD:EE:FF

If you have friends with an adapter like this, or have multiple adapters, with this same address, then be aware that you will not be able to use them at the same time whilst in range of each other.

The MAC address (- the ’11:22:33:DD:EE:FF’ bit) should be unique – unfortunately for these adapters they are not and this means that you may have issues trying to talk to these adapters if another one with the same MAC address is in range

Also, these adapters appear to have persistent ‘enter pin’ issues – if you have to repeatedly enter the PIN each time you have reset the adapter (powered it down, and then powered it back up) then you will need to get the adapter replaced.

Unfortunately the PIN issue lies with the adapter and there is nothing I can do to work around this in the app(it is not a software problem) – the adapter hardware needs to be fixed :-/

I have added a note to the wiki page about these new clone adapters.

Interesting, I am waiting for delivery of a 1.5 ELM 327 Bluetooth OBD Scan adapter from ebay.
I know its too late now but is it possible to identify the ones with iffy Mac addresses before buying?

I just registered JUST to answer this problem. I just realized that my Bluetooth reader has that same MAC address and I had the pass code issue as well – until I purchased Torque Pro. I’d highly recommend purchasing Pro anyhow just for the added features. Plus, this guy has made a truly amazing app! I’m a data junky, so all the logging really impresses me and those I work with. I’m also looking forward to setting up my own torque.php page to log my data on my SQL Server.

Anyhow, I’m pretty certain the paid app won’t have to re-sync Bluetooth each time.

I had upgraded to Pro b4 I joined, there was no change to the behaivior for me.

Ebay Seller is sending me a new BT part to DIY install in the unit. If this doesnt work, I will install one of my BT circuts from my Arduino projects.
I ordered another unit from another seller anyhow, I picked this one up cause it was tiny. Got a short right angle cable to use so I can relocate the larger unit I just ordered.

Piemmm:
I dont blame the app, its clear to me that its the BT circut.
I was only hopeing a work around might be possible.
But I understand why it is not.

I just got a ELM 327 and I am having problems pairing.

I get: Cannot establish communication with 00:1D:4F:8B:9F:29

There is another blue tooth device CHX which keeps rejecting my passwords 1234,0000 and 6789.

Am I screwed??

I’ve got the ELM327 unit sold by “supertiger” on eBay item #190900535147. It is one with the infamous MAC address.

I had trouble entering the PIN of “1234”. It turned out that it must be entered in the first 60 seconds of the connection.

After that, performance has been exemplary.

Mick> unfortunately it sounds like your adapter may have chosen that moment to stop functioning

Nothing has changed in the OBD handling side of things for several updates that would affect connectivity to the adapter (there are also several unit tests that are run before each update is sent out to verify that everything is working properly)

Check that a settings hasn’t inadvertently been changed and that you aren’t in range of another 11:22:33:DD:EE:FF bluetooth device (as these will interfere with each other and prevent reliable connections)

The issue is your phone unfortunately. Samsung have stopped the role out of 4.3 due to Bluetooth issues. Its not likely to be resolved any time soon if the forums are anything to go by. Not happy.

Hello,

I’m a brand new user, and this sounds like it could be similar to my issue, but I’m not sure. Here goes:

I already have dual Aeroforce Interceptor gauges mounted in my dash. I purchased an ODBII splitter cable, and a cheap ELM-327 (probably a mistake, and possibly my problem. I think I did notice the MAC is 11:22:33:DD:EE:FF when I went to pair it).

My goal is to mount a 10 inch table in the car, to be used when I’m at the track.

I only have the free version of the app so far, as I wanted to try it out first. But what I have found so far is that if the Aeroforces and the BT adapter are both plugged in, the Aeroforces seem to work, but the Torque app says searching protcol, or something like that. If I plug in the adapter and not the gauges, I can at least get the torque app to talk to the car (can see engine RPM change) I tried switching the setting about ELM327 auto timing adjust, to no avail.

So, do you think this may be solved by upgrading the app? I kind of doubt that. But, in your opinion, will buying a more expensive BT adapter allow me to do what I want, or am I going to be stuck unplugging my Aeroforces anytime I want the gauges on the tablet to be active?

Since one works and the other doesn’t, I wonder if it is just a MAC address conflict.

Thanks in advance.

Edit…I’ve been thinking….that MAC address is on the Bluetooth “side” of the equation. So it’s not a Bluetooth issue, because these gauges are wired. But it looks like some kind of conflict on the ODBII “side”. So, now I guess my question is, what, if anything, can be done about the apparent conflict between the Aeroforce gauges and the BT adapter/Torque combination?

Hi all….New member here and love the torque program. bought an ELM 327 from Amazon and have had no real issues as of yet. sometimes it asks for Bluetooth password and sometimes it doesn’t, not really a big deal if it does. Not sure if this is the correct topic or not to ask this question but I have had this happen 2 times now on my 2002 Toyota Sequoia where the ABS and VSC lights flash rather quickly about 15 times and then shut off off?? Truck seems to run fine when this happens but I thought this was kinda odd. possibly a glitch somewhere in the whole system where it is trying to process to much info?
