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.

Tips:

• when setting up a companion, don't forget to do a clock sync and do (set) adverts.
• put your repeater on the internet map

Plan: Donate for a Heltec Meshtower

For our new Hackerspace location, we would like to install a Heltec Meshtower. This device is a standalone, battery and solarpowered Lora device that can be installed outside. The device itself will cost around 200 euro, excluding mounting (to be determined)

If you would like to participate (donate), please join!
