Install MAVLink (if you have not already done so).īuild libraries for your target dialect, specifing WLua as the target language.The MAVLink generator ( mavgen) can build this plugin for a dialect in the same way as it builds MAVLink libraries for other programming languages. Generate MAVLink Lua Plugin for Wiresharkįirst you will need to generate a Wireshark plugin that includes definitions for the MAVLink messages that you want it to handle. You will need to regenerate and reimport the plugin (as shown below) if your dialect changes. It also provides an overview of how you can use tcpdump for collecting traffic on a linux computer (for later analysis). This topic shows how to generate a Wireshark plugin for a particular dialect file and install it on Wireshark, and how to perform basic filtering. Rebuilding QGroundControl so you can use it analyse custom messages is much harder! it is easy to update for new custom messages and dialects.you can use it to analyse traffic logged on a companion computer (this allows analysis of traffic between the companion computer and flight controller, which might otherwise not be visible to Wireshark).
it can view all traffic on a network interface (GCS tools like MAVLink Inspector often only analyse incoming traffic).The benefits of using Wireshark over other alternatives are: Wireshark is an extremely popular "general purpose" network protocol analyzer that can be used to inspect and analyse MAVLink traffic.
