Hi All.
Well I cannot connect to OBDII in Carman.
I bought this device.
http://cgi.ebay.co.uk/Bluetooth-ELM3...item3a61f77f37
Now everytime I try to connect this device in CARMAN appliaction, it instally disconnected.
Everytime I press connect, it gives message of disconnected.
But now that you mention you have the same problem, I wonder if there was an update some time ago that broke something.

Hi makkan00
Maybe Carman's report files can give you a clue. They are ordinary text files in your N900's home directory with names like 'carmand_logYYMMDD_HHMMSS.txt' (YYMMDD and HHMMSS are date and time when the log file was created).
Looking through mine I see that carman actually thinks that my Bluetooth OBD is version 1.4, not version 1.3 as it was advertised! Things get even more confusing if you look here: http://www.elmelectronics.com/obdic.html. According to them there are no version 1.4 as i seem to have or 1.5 as yours is described as being - it should be 1.3a or 1.4b! Anything else is a clone.
Also the datasheet here:
http://www.elmelectronics.com/DSheets/ELM327DS.pdf
says 'The descriptions for PP 0E bits 3 and 4 were accidentally reversed in the previous datasheet (document ELM327DSG), and have been corrected' which may mean that depending on the CAN bus settings your car needs something might not work properly.
Good luck,
Sophie x

Can you please explain how can I explore that file, should it be through computer, x-terminal or file explorer?
If I can get access of that file, I can change it to 1.3 or 1.4 and give it a try.
Well today I tried to alter the conf file and deleted the mac address of OBDII from there and entered unknown.
Now when I tried to connect it, it picked up but again disconnected. Checked the conf file, and OBDII mac address is there.
So I guss you are correct, I may get luck if I change the file you mentioned.
Waiting for your response.
Cheers.

OkI have installed WinSCP and connected it to my N900.
Gone to home and then to user and opened carmand conf file.

Before somebody says try it on other car, I would like to say, I have tried it on my Ford car too, but same error.
so I assume it is to do something with ELM327 or N900.
Strange thing, it works fine with my laptop, netbook, and my wife's android phone without any problems....

libobd????
I guess that is something to do with CARMAN.
Am I correct, is there a way to correct it?
Cheers.

Hi makkan00 and jlu
I don't think this is my week. first I burnt a friends ECU, then my spare ECU and now my Bluetooth OBD doesn't work in my car although it does in my bf's I guess that things just working for me was too good to be true to last 
I've had a look through the ELM327 datasheet too and will try building the carmand part of carman with jlu's suggestion and some of the suggestions in there and see how I get on.
Sophie x
PS @jlu I have tried to install ESbox but it won't work properly because it can't find 'xulrunner' but Kpackagekit says it is installed. I'm a bit worried that ESbox says to only works on Ubuntu and needs xulrunner version 1.8 whereas I have Kubuntu 10.10 and xulrunner 1.9 do you have any ideas I could try?
PPS if anyone knows of something like Hyperterminal for the N900 that would be rather handy...

My method:
1) On a PC, go to here.
2) Go into the two carman-theme-?? folders and download the .deb files to your PC.
3) Rename both .deb files to .tar.gz files.
4) Use 7-zip to open the files and keep going through the folder tree until you get to the ones in the themes folder - drag these onto your desktop (or wherever).
5) You should now have two folders, one called eclipse and one called offroad.
6) At this point methods vary, but you need to get the folders into \usr\share\carman\themes on your n900.
7) I copied the folders via usb onto MyDocs, then "sudo gainroot"ed, created the requisite folders in the \usr\share\carman\themes folder, and copied the contents of the two folders into there.
