Meshtastic Problems - And Another Off Grid Messaging System

Video Description

Meshtastic allows you to send off grid messages between devices without having to use the internet or a cellular connection. But Meshtastic isn't perfect, especially not when used for large mesh networks. However there exists a different, older and more mature project, that does basically the same thing as Meshtastic, but tackles some of the issues differently.
