Any recommended models? Bluetooth or WiFi?
Kia Soul Electric Vehicle Forum and Electric Vehicle News
and at the end they state -ELM327’s and derivatives are the devices of choice if you want cheap, run off the mill hardware that works without any DIY. They can be obtained for about 12 euro’s. It is somewhat slow, though we’ve been able to get more out of it than we ever expected. Take good note of the following remarks:
The ELM is designed for OBD-II, diagnostics with a focus on emissions. The Zoe and Fluence ZE use quite different message types that need some tweaking. This makes it prone to firmware versions.
Get a Konnwei / Maxiscan KW902. Others may work, most do not. Especially the 5 Euro blue ones usually do not. We have not noticed different firmware versions in the KW902′s, so as of now it is a safe bet. The advice came from the LeafSpy guys by the way, so it’s not just us, we are simply endorsing that advice, based on our own experience. Here is the quote from the people who build the LeafSpy app:
Due to a recent cost reduction (and feature reduction) many of the cheap ELM327 OBD-II Bluetooth adapters from Asia no longer work with the Leaf and report themselves to be version 2.1. The only one currently recommended is the Bluetooth Konnwei KW902 which still supports all the needed ELM commands to communicate with the Leaf.
The Maxiscan KW902 and the OBDII 2 KW902 Scan Auto Scanner look the same, are probably identical inside and also work.
Note that they are sold with Bluetooth or Wifi connectivity. The current Android application only supports Bluetooth.
We have also reports that a OBDLink LX modules work, at least the modules reporting V1.3. They look exactly like a Konnwei / Maxiscan. These will be usable starting CanZE version 1.9. The ones we’ve seen are a lot more expensive than the Konnwei’s though.
We’ve seen another branded version that works. It is called an iKKEGOL® Mini V1.5 Bluetooth Wireless OBD-II (Links: Amazon), but we have not seen it on sale any more and it seems to have slight timing problems. We do not recommend it but you can try if you happen to have one.
The cheapest knock-offs do not work. Most contain stripped logic cramped in the spare room of their Bluetooth controller and these are too limited to work for CanZE.
If you experience problems with dongles other than the KW902, we are unable and frankly, unwilling to help. The KW902 works, it is relatively cheap, and it is simply not worth, if not impossible, to cross check 50 unbranded, unversioned knock off dongles against 75 Android devices. If you insist trying other than the dongles that we know work, you are on your own...
IMPORTANT: leaving an ELM327 plugged into the SAE J1962 connector might open up the car to serious security risks. Remember that, defined by the standard, the connector is always powered and at least part of the ECU’s can be awakened even when the car is totally powered down given the proper commands. Since the Bluetooth pairing code is 1234 or sometimes 6789, this is a serious attack vector. Use at your own risk.

"Another annoying thing is that the dongle does not seem to work anymore. The red power light turns on, but the blue BT light doesn't. Pressing the button doesn't help"
"I had this too, after reboot/restarting my phone I could make a bluetooth connection again. So it is possibly more related to the phone/Torque Pro."
"Unfortunately restarting my phone has not resulted in a new connection with the dongle."
"Did you also try to remove the bluetooth connection on the phone to the Konnwei and try to pair again freshly?"
"My phone is connected to the Soul."
