Well I ordered it and for my 5 quid it arrived in the post within 2 weeks and was accompanied with a CD containing a lot of thrown together downloads - nothing else though - like instructions on what you need to install !
My PC picked it up and registered it as a blue tooth device immediately.
I installed the ScanTool software and that just hung everytime it tried to configure itself. Lots of uninstalling, reinstalling & rebooting - still just hung. So tried another piece of software EasyOdbII. This didn't hang, but it when it configured itself, it couldn't find the ODBII Reader. Luckily the log said it tried COM3, COM4 and COM5 - and Windoze had registered it as COM7 - so that was the problem. Quick shify at the EasyOdbII info and it says it can use ports uo to COM25 - but I couldn't find any way of getting it to do that - so ditched that software as well.
Did a lot of trawling through the web to find info on ODBII and downloaded various PDFs etc and its obvious the ODBII reader is very much like a modem that you use to hook into the 'network'. The downloaded info contained various commands to send to the reader and what responses to get back - and they're all text - so a good old fashioned terminal emulator should do the trick.
That's when I found out that the 'trusty' Hyperterminal isn't shipped with Windows7 - so downloaded and installed a 3rd party Hyper terminal. Fired it up, configured it for COM7, typed in a command and hey presto got the expected response back.
Cooking on gas at last
So after playing around with the commands to configure the reader and all working well - I then tried to get some info from the car! Every command I typed in got "Unable to Connect" - meaning the ODBII reader couldn't talk to the Freelander - bugger!
So at that point I called it a day.
I'm confident it will talk to the Freelander, I probably need to tell it which protocol to use or something. I'm also confident it will talk to other modules, not just the engine, as the i930 can. I presume the tablet (Android/Apple) software would communicate with the reader easier as well.
So I suppose the moral of the story is that you pay your money and you take your choice. I think a cheap reader and paid/download tablet software will give you a decent view of your engine. Paying a bit more for a Freelander packaged device like the i930 is decent money spent if you want a quick, turn key solution.
I want to create some bespoke software, so I'm going to persevere with this little device and hopefully I can get it talking OK. But it will take some time.
It is amazing in this day-and-age where information on everything is available on the web, that the ODBII/CAN codes used by car makers isn't !!
