Thread: OBD II iPhone connection on the horizon

What do you see as the big difference between this device and the Kiwi Wifi and other ELM327 based Wifi interfaces that warrants such accolades? The fact that it's a wired appears to the main point of difference to me.

I have no doubt that with a lot of work it would be possible to create an App that largely replicated the capabilities of TestBook/Nanocom/Faultmate. But imo the interface is the least of your worries.

I have had the Kiwi Wifi interface hooked up to my 2000 Disco TD5 today and it is possible to access the ELM327 v1.3 chipset via telnet.

Code:

>at z
at z
>LM327 v1.3

It's kind of interesting reading the OBD-II PID's using the command line:

Code:

>01 01
01 01
BUS INIT: ...OK
41 01 00 04 00 00

The above is a response indicating that no error codes are set. Unfortunately on the Disco TD5 the number of accessible OBD-2 PID's is very, very small. Most return a "NO DATA" result.

I think that any ELM327 (or similar) based interface is going to be flexible enough to send and receive the commands necessary to perform LR diagnosis.

The missing link is the background knowledge required to communicate with the LR specific sub-systems. And ultimately it's effort required to acquire this knowledge we pay for when buying a Nanocom, Hawkeye or Faultmate.
