Update README.md

[ahcorde]

Hi,

I'm trying to understand this repository but I couldn't find enough information here or in the PX4 documentation. As far as I can see this repository contains 4 plugins:

• barometer
• magnetometer
• gps
• mavlink

I included the sensors plugins in this model Tools/simulation/gz/models/x500-NoPlugin/model.sdf and the mavlink plugin here Tools/simulation/gz/models/x500/model.sdf then I launched these plugins with the model inside the PX4 repo executing

reset & make px4_sitl gz_x500

Plugins are loaded properly because I can see the Gazebo traces but I have some questions/doubts:

• Sensor topic are empty ? they are not plublising any data.
• what's the use of the mavlink plugin?

Can someone explain which are the different from using this repo or just the px4 oficial repository?

Thank you in advance

This was the first attempt using mavlink that was later replaced by the in tree gz-bridge.
