Has anyone ever used the windows mobile version of this? I want to know if there are any issues with the bluetooth version of the OBDkey, I mean is there a reason as to why it is half the price of the WLAN version.... heres this link

i can't imagine the range is very far. that's all i can think of though

yeah like if its in a shop you can sit by your toolbox or something. i like to sit in the cars with the ac on and the radio though. so a cable doesnt bother me

^way to make a comment that has nothing to do with the question.

^^certainly not the range of wifi, but i regularly use my various bluetooth devices across distances of 30ft. with no problems. in fact, just the other day i was messing around with something in my truck sitting in the driveway and i had a phone call come in through the stereo. my phone was in my bedroom, a good 40+ft. away through walls/doors. i couldn't actually carry on a conversation though, the audio was terrible.

^^^i would guess it's probably because of the advantages wifi would give in a professional setting. far superior range, easier to initially connect to and stay connected to multiple devices at once, compatible with a wider variety of devices (bluetooth still isn't THAT common, especially for pc's/laptops/netbooks) faster transfer of data, ability to receive and transmit simultaneously, etc. i would think real time monitoring might be more accurate as well, but someone more knowledgeable than i in the specifics of bluetooth/wifi might be able to confirm/deny that?

bluetooth is designed for PANs or personal area networks. operating range radius is roughly 20' though I think it's "guaranteed" for 10 meters or something like that. they have different classes based on how much power you run through it I think. the problem with bluetooth is that different devices tend to write their own stacks so it works differently in other places. it's also slow, though I wouldn't think ~2mbps would be a deal breaker when moving so little data from one of those things. I doubt the processor can read/write data to a socket that fast anyway. The only REAL benefit I see to WLAN over bluetooth in this application is that multiple machines would be able to connect to the device without renegotiating a connection (key exchange on bluetooth).

yea that sounds about right.

what's weird is when i use my bluetooth headphones to listen to music and have it connected to my computer my range is like 10' max. connect it to the iphone and i can be anywhere in the apartment pretty much and leave the phone in the living room and it picks up perfectly. kind of weird to me that a phone does a better job that a computer

That's what I ended up with. Works like a damn champ, IMHO well worth the extra money to go with a WIFI solution. It's 802.11a, even though I says a/b/g. I can't imagine bluetooth being at all suitable for any sort of realtime metrics, given the bandwidth, especially if you are tracking multiple things.

WLAN uses an ad-hoc connection, so there's no renegotiation there either. Just get in range and it works.
