OBD2 Car Software
This could be a big or a small job, I don't know as I'm not a developer but...
Is there a developer out there that is familiar with the OBD2 protocols and connectivity with a car's ecu? I would like an application that will connect via bluetooth to a bluetooth OBD2 adapter so that I can have a realtime visual on my car's engine management system. An app that is available for Palm and Windows is OBD Gauge (http://www.qcontinuum.org/obdgauge/), but being a maemo device I want to take it further, in someways to give mechanics an alternative way to look at a car's information. |

Re: OBD2 Car Software
How about Carman?
It's getting there... I hope. I use it with my N810, but waiting to use it with N900 as well. |
Re: OBD2 Car Software
Thanks guys! Didn't realise that this existed!

Re: OBD2 Car Software
+1 for this, i think there is another post regarding this, someone put this link http://www.dealextreme.com/details.dx/sku.16921 which is a bluetooth adapter to work with the handset..

Re: OBD2 Car Software
The fundamental protocol of most of these devices is quite simple.
>90% use http://www.elmelectronics.com/dsheets.html chips, look at the datasheet for the elm327. In principle, you could just use the above mentioned bluetooth adaptor from DX, and your favourite serial terminal program. For some things, such as reading out fault codes, or resetting check engine lights, this would be quite adequate. |
Re: OBD2 Car Software
Carman was a good start/attempt for N8x0 series... I don't know how far anyone's got porting it to the N900... I don't know why they'd try to be honest with you. From a development point of view the amount of work required to port over the entire enlightenment engine (that Carman's built on), VS just building a new app from scratch just doesn't make sense.
So on that note Spenc3 and I have started the Carocell project; interfacing to obd2 is dead easy, as already pointed out... the tricky part is handling all the automatic setup/teardown of bluetooth, and of course having a nice flexible GUI system for handling and displaying that info. At the end of the day the only really practical use is for reading trouble codes and clearing them, which is the most difficult part of an app because it requires you to do a bunch of binary comparisons and evaluations in order to determine exactly what's what. Anyways long and short of it is that there are people working on it... |
Re: OBD2 Car Software
i have used carman , but still use my e66 whit obdscoop , whit obdscoop you can erase error;s and clear out f,exs check engin light
did send a mail to obdscoop and ask if he was going to make it for maemo but that was no plan for that :( but if u have a symbian phone and the obd2 bluetooth adapter it is a great app if u have a car whit obd2 regards Just |
Re: OBD2 Car Software
OBD on my n900 would be awesome, I hope this comes to fruition

Re: OBD2 Car Software
once you have a prototype i will be willing to test it for you (i'm a mechanic buy trade so plenty of vehicles at work to test on) would be good to have a range of programs to check ecu's carman is the only one i can think of at the moment thats about and works on the N900

Re: OBD2 Car Software
Carman on N900 for play only and not for help.

Re: OBD2 Car Software
I know this is an old thread, but there apears to be a relatively new app called OBDAutodoctor in Nokia store that can monitor your car.

Re: OBD2 Car Software
Thanks for the information.
Lite version (free), available for N9 but not N900: http://store.ovi.com/content/211199?...e=search&pos=1 Pro version ($9.99), available for N9 but not N900: http://store.ovi.com/content/216026?...e=search&pos=2 Product website at http://www.obdautodoctor.com/download.php confirms only for meego/N9 devices. How difficult do you suppose it would be to port to N900/freemantle if asked? |
Re: OBD2 Car Software
Nothing is difficult if you know what you're doing... I would also like an N900 port of OBDAutoDoctor. First step, email them to ask for one.

Re: OBD2 Car Software
FYI: your car has to have an OBD II compliant port, and follow the agreed protocol - some cars were built up until around 1996 with OBD II ports, but are only accessible with manufacturer-specific tools.

Re: OBD2 Car Software
I have managed to get my hands on an ELM327 BT adapter, so I tried the app. It works fine.
http://static.zooomr.com/images/10130048_17fa13c927.jpg http://www.obdautodoctor.com/scantoo...e-for-symbian/ Apparently, they have received a lot of requests to port it to N8 and they are working on it. Perhaps if they receive a lot of requests to port it to N900, they might consider it, too? |
Re: OBD2 Car Software
There's an answer from the devs on impact's link now:
