    I have reported my crashing issues to OBDLink & they have been helpful so far. They sent me a data logging MX+ & I have sent logs to them to analyze.

    I find that Scan My Tesla crashes & closes when the OBDLink locks up. Does SMT do the same for you?

    When driving, the app closes and crashes I think. Only happened twice, due to lack of driving.

    More likely, failed to connect. Hangs on the "initialize" step.

    I just relaunch the app and select car and device, then it usually connects. This ire required about 2/3 of the time. Only a third of the time do I connect the first time.

    About 5-10% of the time, have to go to car and pull out the LX to connect. This also happens when driving.

    Because I have the LX under the cubby, easy to do.

    Hmm, got a LX a few weeks ago, haven't used it much, but tried it last night after some of these reports and it had indeed locked up and wouldn't connect.

    Had to unplug/plug it back in. For those of you in contact w/OBDLink let them know that it appears to affect multiple people. Happy to help troubleshoot, too if they want more people to collect data.

    The freezeup issues have always plagued the OBDlinks at least in the Tesla. Had it with the LX for a year then again with the MX+. Kind of inexcusable for an otherwise top-end product. But I think it's just that it's operating in an unusual condition that it isn't normally subjected to, either with no typical J1929 OBD data/connection, or just the sheer insane amount of data on Tesla's CAN network.

    One thing you can do is make sure it is powered by a switched 12v that turns off when your car goes to sleep. I know a lot of Model 3 harnesses improperly supply power from the security controller instead of from the lighter socket accessory circuit as they should. Moving the 12v connection older will at least turn off power to the OBDlink so it starts up fresh when you wake the car up

    Don't give them excuses or you risk being like them :). It's just a lazy development where they don't care about programming and testing the code correctly. It pretty much looks like memory leaks - it hangs even on a sleeping car after few days.

    Let's do the support of your server on SMT and let's forget obdlink like a nightmare.

    Please elaborate a bit...

    My harness on the MS only connects to the CAN bus connector.

    Car not sleeping at the moment, but green light is on the LX. Can't connect unless I open a door...

    I wonder why expensive ODBLink products are hanging while “el cheapo” ELM327 adapters aren’t.. sure, you get about 10x less throughput, but mine hasn’t hung once in the last year I’ve used it.

    I noticed recently getting some debugging traces (?) on my SMT app.

    I wonder if anyone noticed the same display?

    Note: I don't think having set any Debugging Option in the Developer Option
    of my Android Samsung Galaxy Note phone.

    I updated the SMT app to 2.11 Beta but I still get the debugging traces.

    I'm using an ODBLink MX+

    I have a 2018/10 Tesla Model 3 LR AWD with the latest Software version 2021.1.4

    In the betas, Signal lists -> select 'BMS' in the pulldown. If you are looking for individual cell voltages. More stuff under Battery.

    The BMS data is the best part. Seeing every string, cell temps, knowing when I have regen, cell mismatch, and early warning of failing module or string.

    Amund, I think today there is a new market opportunity for Hundai owners.

    It would be ionic, I mean ironic, if a Tesla app helped them avoid fires.

    Meanwhile, I don't want to kill my Tesla, so I won't be parking next to other electric cars until the recalls are finished.

    I'm not making excuses for them, I'm just speculating an explanation.

    I was talking about 3/Y rear console harnesses. I don't know how the S/X diagnostic harnesses work.

    We have the Maxwell cable for our S. The OBDLink MX is always powered, even when the car is off.

    @amund7 Great, thank you, I didn't noticed the "Debug off/Show debug info" toggle switch.

    I was thinking that one of the recent Tesla updates affected the decoding of the CanBus like with the 2020.20.5

    May be can you set off the debug in the non Beta version?

    Do you know who makes one like that? I'm using the one from gpstrackingcanada.com.

    Do you have enough beta testers for the iOS app testing the connection to CANServer?
