The Leaf Spy Pro application allows anyone with a Nissan Leaf electric vehicle, Android device with Bluetooth and a ed ELM327 OBDII Bluetooth adapter the ability to monitor their battery and other vehicle information normally visible only to the dealer.

With the release of version 0.39.97 LeafSpy Pro now s two Bluetooth 4.x LE approved adapters. The recommended one is the LELink available from Amazon. Bluetooth 4.x LE has the advantage of not needing to be paired and lower power from both the Android device and the Leaf. The LELink is highly recommended and also works with the iOS version of LeafSpy Pro.
