There are both 5V and 3.3V version for the adapter. If you mess up with the voltage, damages may occur. For example, a 3.3V arduino should never be powered by 5V adapter.

You either stack a WIFI shield for Arduino or simply a WIFI bee which can be plugged in a xBee socket.

I will take a look at your code!
As for iOS App, are you capable of iOS development?

Response is a zero terminated string with padded space between each 2-char hex.

Replay a saved log file is a feature to be added in my plan.
An Arduino library which lets Arduino to control the emulator will also be developed.
The source code of a command line tool will be released soon.

The most likely case is that your car does not use a protocol supported by the adapter. Only these protocols are supported:

CAN 500Kbps/11bit
CAN 250Kbps/11bit
CAN 500Kbps/29bit
CAN 250Kbps/29bit
ISO9141-2
KWP2000 Fast
KWP2000 5Kbps

It is possible some cars are not supported. We have listed all the supported protocols on the product page and they are:

CAN 500Kbps/11bit
CAN 250Kbps/11bit
CAN 500Kbps/29bit
CAN 250Kbps/29bit
ISO9141-2
KWP2000 Fast
KWP2000 5Kbps

If you want the adapter work out of box without any programming, you can only use iPhone as we have only developed App on iOS at the moment.

BTW: BLE device does not need pairing or any pass code.

Good to know that.

The Data2KML utility is open-source. The online service will be improved shortly.
