wanna check this out?
so my G/f wanted to know what i wanted for xmas, and i told her an OBDII scan tool.
so in the process of finding the one for her to buy for me, i got lost, and found i needed some help, along with a pondering of something that transcends my search for an OBDII scantool.
i need a scantool to:
1. connect to a range of devices. laptops both old and new, smart phones old and new.
2. ability to take advantage of all 5 major protocols (VPW/PWM/ISO9141-2/CAN/KWP)
3. be priced nicely for me. i'd love $100, but maybe that's not realistic.
then my options became:
serial: (nah, too old. do new laptops even come with serial ports? also, no cell phone support)
USB: good for connecting to laptops, but not with smartphones
Wifi: good for most smart phones, great for all laptops.
Bluetooth: standard on all smartphones i think, bad for old laptops.
so i think the answer to my question of which i should choose ultimately becomes a question of where the market is going.....
i know vitality of scantool.net is on here and so is paul(?) from obdpros, so i know they have respective products to offer
Personally with that requirement list I'd go for the bluetooth OBDlink. Pretty much all smart phones by this point have bluetooth it built in, and any laptop that doesn't have it... you can get a dongle for < $10.
I would recomend OBDLink available from the mp3car.com store
no smartphone apps exist for bluetooth connections.
Well if you're basing your decision purely off of existing applications, then you're limited to the iphone and wifi.
DevToaster's REV ( http://www.devtoaster.com/products/rev/ ) is WiFi based.
We have investigated the new hardware integration features of iPhone OS 3.0, which in theory allows us to support Bluetooth and Dock connector-based hardware. However, after confidential discussions with Apple, we have concluded that WiFi is still the most reasonable option at this moment—both from technical and business perspectives.
AKA apple's got them by the cajones....which means for the foreseeable future, wifi may just be it, based on the installed user base of the iphone.
unless android can come up with something....
So I was bored yesterday and pushed out a quick graphical test for my droid. I don't yet have a bluetooth obd2 tool, but I'm planning on adapting Chunky_Ks's obdsim to output from my laptops bluetooth so I can get this written perhaps without a tool. I know the graphics look crappy but I've yet to port over the original drawing code from my old GaugeDisp program to this, and it's just a proof of concept to see what the graphics engine itself can do and thus far I'm impressed.
Perhaps I'll have to take a lesson from the iphone tool for layout and feel of the app
Great work so far!!
Ill be following this closely, I have been searching for an android app that would work with obd.
So far, there is barely a mention of it.
I just picked up a cheap elm 327 bluetooth for $60. It comes with windows mobile software that is supposed to work over bluetooth.
I have yet to test it out and who knows about the quality ( its a china knock off type). but if it works its a killer deal.
Please keep the thread updated!
