Well, greetings to everyone here. Wasn't entirely sure what to file this under but this seemed the most logical.
I have a Raspberry Pi 3 here, with this kit https://www.element14.com/community/doc ... en-display
I've followed a couple of guides on how to connect to the OBD2 port of a car but I just can't seem to actually get the result any of the guides show.

And I'm pretty sure I've tried others, too.
I have both a ELM327 interface which can be approached by bluetooth as one which has a USB connector. However, whenever I attempt to connect through bluetooth I get a "org.bluez.error.notavailable" for which the most common suggestion was "fix your bluetooth installation".
Well, one more guide for doing that and the result hasn't changed.
I've also had "this device has no services which can be used with Raspberry Pi" (which is obviously a lie as those tutorials prove)
As for the USB one, I've been trying to get a read/write connection going but I'm pretty sure that I'm either misunderstanding the instructions or perhaps I'm mistaken in how to achieve my goal.
And my goal, as with most people that attempt some Frankenstein project with Raspberry Pi and OBD2, is to ask the car's computer for information (RPM, speed, warning lights, did I just run over a cat? (at this point I'll take any information I can get)) and show it on the screen.
Any advice and suggestions are very much appreciated because I've run out of ideas on what to try. If you tell me that ritualistically sacrificing a chicken will make it work then I'll consider it.
