Are you using an official ELM327 device? It looks like there is a connection issue

[Fernien]

I think so. I bought this one https://www.amazon.de/gp/aw/d/B00NSNNNOQ Could you check for me ? And if this is the wrong one could you tell me what to get instead ?

[alistair23]

I'm not sure, I can't read German. The fact that it is responding with an unknown protocol isn't a good sign. You are also getting a CAN error

[Fernien]

I thought I might have to assign the can 11bit (my car uses can 11bit) in my program. But I couldn't figure out hoe. Could this be the problem ? Or is it really an connection issue ? I can connect the obd adapter with an app without any issues

[alistair23]

Sometimes the apps work when this doesn't with the knock off chips. The unable to connect message it's probably a good place to start debugging. See if you can figure out why you get that

[alistair23]

Otherwise try specifying the baud rate or protocol

[Fernien]

Could you recommend an adapter for me? I got even more issues with this one. Cant even connect with bluetooth anymore. Gonna sent it back.

I faced the same issue a couple of days ago (issue #134). I tried with another OBDII adapter and everything was fine

[Fernien]

Thanks for the information. Would you tell me which obd adapter worked for you ?

Actually with the adapters from OBDLink i'm fine with a lot protocols ( my preference is always the one with the usb cable http://www.obdlink.com/sxusb/). If this adapter doesn't work as well, i guess that the issue is your car.

But before buying a new device, have you tried to install Torque app (https://play.google.com/store/apps/details?id=org.prowl.torquefree&hl=it) and pair it with the device you already have?

"ELM327 v1.5" means that the adapter does not include a genuine ELM chip. Anyway, another simple check would be to update python-OBD to the lastest GitHub version and switch engine on before testing. If the error occurs with ignition on, either the adapter is not properly connected or it is not able to support the actual protocol.

I got the latest version because it was the first time ive tried it. I bought an ELM327 v2.1 adapter. It will arrive next week. If this will fix my issue I will update this thread. Thanks for the information

I tried the new adapter and it works fine for me. The important thing (which I almost forgot while trying today) is to definitely turn on the battery/engine of the car. Otherwise it won't output real data.
