Hi guys,

I know this has been up before, but im trying again.

I have a OBD2 V-Link WiFi dongle wich shows up when enabling the WiFi in the car.
Is it possible to make a application to read out stuff like oil temp, coolant temp, etc?

It probably is, you just have to find out how the dongle works, how does it display the information, send me a link to the dongle you have, its not a bad idea, maybe I can make an app for something like this now that Im done with exams.

EDIT: Nvm, they all seem to be using the same protocol, I just ordered one off ebay, so when it arrives Ill try to get an app going for it.

Awesome. I run one of these dongles in my forester and run torque on a permanent mounted tablet, but would buy another if we had an app for the mazda infotainment.

That would be very interesting. I really lack some gauges (like oil temperature, f.e.) in my M3 that would be great to be able to see from the MZD connect like in the Nissan GTR

there is the command smdb-read in the CMU where you can have some of this values. I remember brake position, fuel pump, engine rpms are some of these. Hope someone can make this app.

judging by some of the options we have already available, the CMU is already connected to the CAN bus, so it doesn't require a dongle to connect to the OBD2 port, but it's restricted by the firmware to only certain things, or the default apps have only a few things implemented - which is good from the safety point of view - hacking through wifi won't allow anybody to take over control of brakes/engine/steering etc.
but... as it is linux, and we already have root access, it should be entirely possible to run own distro on it, or remove restrictions, and then cross-compile fully featured app which can read everything.
