Projects:Meshcore

Hackerspace Nijmegen has a Meshtastic node. Given the limitations in reach without the internet with Meshtastic, another open source project has become popular recently: Meshcore. Meshcore has a clear distinction between repeaters and clients (companions) and seems to be a more robust implementation of Lora.

As there are hardly any repeaters (October 2025) in Nijmegen, we have setup a Meshcore repeater in the space as well.
