    Hi, I’ve just got a kit to connect to scan my Tesla. But I’m having problem with Bluetooth connection to the obd2 adaptor, connecting to a Samsung galaxy note 20 plus. The connection won’t stay up for longer than 30 seconds before it drops again. Has anyone any experience with these things? Is it likely to be a duff adaptor and if so can anyone recommend a good brand?

    Yeah thats the one I went for. Set up isn't bad. The only nervy bit is ensuring your car is shut down before you connect to the CANBUS. The trick is to log out of everything that might wake the car. Apps, teslafi etc. The back panel is also quite easy to get off.

    When it works it works well. It's just the longest connection I've had is 30 seconds (shortest 1 second) and when it reconnects it takes a while to get the data back. Its very frustrating. I think I need to drop emobility a line.

    Don't want to be the bearer of bad news (or good depending). But you don't need to spend more than £25 to get the equipment for SMT. As long as you've got the Tesla M3 OBD interface and a Bluetooth dongle you'll be sorted. The one I got was here. Might be worth a punt?

    The £25~ package that includes a bluetooth dongle works well with my SMT app. Only issue is that it's Android only. If you want to use the app on iOS you'll need a WiFI OBD dongle which costs £90+

    So. The scan my Tesla guys rang me. And I made a few phone changes to fix the connectivity issues. And it just made it much worse.

    Frustrating because I don’t know if it’s the phone or the odb2

    Yeah I’m trying another phone tomorrow. It’s a cracking app when it does work. Looking forward to fixing the connection issues

    It’s the update no one asked for!!

    I’ve just been for a drive using a blackberry key2 to run scan my Tesla. In 30 minutes I only had one disconnection. This Makes me think it’s definitely an issue with my phone. @speedyranger74 you’ll probably be running similar version of one ui to me. Did you have to change any setting to get a solid connection? I’ve removed scan my Tesla from the “optimise apps “ settings to ensure the phone doesn’t apply battery saving to it but this doesn’t seem to help
