<h1>[Teaser] How to reverse engineer communication protocols of embedded devices - Sat, Feb 16, 2019</h1>

<h2 id="sneak-preview">Sneak Preview</h2>

|
|
<p>These letters. Such announcement. Many words.</p>
|
|
<p>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.</p>
|
|
<h2 id="1---mc3000-charger">#1 - MC3000 Charger</h2>
|
|
<p><a href="https://www.skyrc.com/MC3000_Charger">MC3000_Charger</a> 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.</p>
|
|
<p>The Windows software provided by SkyRC can program each slot individually to support different types of batteries with different charging capacities.</p>
|
|
<p>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!</p>
|
|
<h2 id="2---lw12-wifi-led-controller">#2 - LW12 WiFi LED Controller</h2>
|
|
<p>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.)</p>
|
|
<p>Sometimes there are simpler solutions. This is what the second article will be about.</p>
|
|
<p>The controller itself comes by many names: <a href="https://www.amazon.de/Foxnovo-Wireless-Strip-Regler-Smartphone-Tabletten/dp/B00Q6FKPZI">Foxnovo</a> and I remember buying it as a <a href="https://www.amazon.de/LAGUTE-Strips-Controller-Android-System/dp/B00G55329A">Lagute</a>.</p>
|
|
<p>KTHXBYE.</p>
