Sneak Preview

These letters. Such announcement. Many words.

In the next few days I will publish two - not one - but two articles on how to approach a problem on how to reverse engineer protocols. There have been to applications I looked into to code a library for my home uses.

#1 - MC3000 Charger

MC3000_Charger provides an USB and Bluetooth (BT) interface (Spoiler: I am not covering the BT interface. Not yet). The USB interface is used to update the firmware and to program and interact with the charger during charging.

The Windows software provided by SkyRC can program each slot individually to support different types of batteries with different charging capacities.

As a result of my analysis, and this will be one of the upcoming articles, I reversed the application and wrote a Python library. To do so I dissected a .NET application. So no big magic here!

#2 - LW12 WiFi LED Controller

This was a tricky one. It is a low budget Chinese WiFi LED controlled with a mobile app. The Android app I looked at was encrypted using a separate VM layer on-top of the Dalvik engine. (Spoiler: No need to reverse this, and I did not do it.)

Sometimes there are simpler solutions. This is what the second article will be about.

The controller itself comes by many names: Foxnovo and I remember buying it as a Lagute.

KTHXBYE.
