The Leaf Spy Pro application allows anyone with a Nissan Leaf electric vehicle, Android device with Bluetooth and
a supported ELM327 OBDII Bluetooth adapter the ability to monitor their battery and other vehicle information normally
visible only to the dealer.
Due to a recent cost reduction (and feature reduction) many of the cheap ELM327 OBDII Bluetooth adapters from Asia no longer work with the Leaf and report themselves to be version 2.1. The previously recommended Bluetooth Konnwei KW902 OBDII adapter is also no longer recommended as a batch of defective ones have made their way into the market. These will basically short out your Leaf's CAN bus (or any CAN bus they are plugged into). But when removed do not seem to cause any lasting damage.
With the release of version 0.39.97 LeafSpy Pro now supports 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.

Using more than a year now. Great app. Say what it does and absolute must have for any Leaf user. Saved me from stalling more than once. Well done LeafSpy team.

Leaf spy lite works fine with my pixel 3a and Android 11. Leaf spy pro won't connect or recognise the same Bluetooth adaptor. Shame

Worked great until my Pixel 3XL was updated to Android 11. I can't find any way to send this feedback to the developer. Android 11 had major Bluetooth changes.

I can confirm that this app does work with a Galaxy S10 running Android 10, and a Konnwei KW902 OBD scanner. (2013 Gen 2 Leaf) UI isn't great, but all features seem to work well. Can be a little fiddly at time times to get it to pair, but turning Bluetooth off then on, closing and re opening the app and resetting the adapter seems to solve most issues.
