We added an interactive MeshCore simulator to the site.
Start with First direct message and run it. You will see the message move through repeaters, get a delivery report, and save a path for later messages. The prompt above the map will tell you when to try the next example.
The mountains and woods make the examples easier to follow: mountains block a path and woods shorten radio range. The log under the map keeps track of what happened in each run.
It is meant to show the basic idea. It is not a copy of the firmware or a prediction of real-world coverage.
We also added a Network Tools page with quick explanations of the live map, Health Check, and Activity Analyzer.
Give it a try. See you on the mesh!
