"The Dove" is coming!
As with many things in the Meshtastic community, this project began with the excitement of
creating something useful, the opportunity to serve the community,
and the possibility of collaborating with fellow enthusiasts.
The jkpg-mesh community consists of members who are actively working to expand the Meshtastic network,
but also to show others that Meshtastic puts the power to create hi-tech communication projects
into their hands — with low entry constraints.
From Heltec V3 to V4 – My First Impressions
When first starting with Meshtastic choosing a device was all about the basics: it had to be affordable, well-supported by the community, and ideally feature a display. That led me to the Heltec WiFi LoRa 32 V3. In this blog I’ll share my first impressions on the Heltec WiFi LoRa 32 V4 — what’s new, what’s familiar, and whether this board feels like a step forward for Meshtastic builders.

Since getting involved with Meshtastic, I've kept circling around three nagging questions: 1) How do you actually communicate effectively with just a 10% duty cycle? 2) Is there a “real” application for Meshtastic? and 3) How do you design a mesh that works in practice? As the title suggests, this post is my attempt to dip my toes into the last one—the art (and frustration) of designing a mesh network.

Speaking to friends and reading online, I’ve noticed a pattern: a lot of people think Meshtastic is just a hobby gadget. A toy. Something hikers use to stay in touch — or maybe a tool for “when the big one hits” and the cell towers go dark. That got me thinking: If I had a great idea, could I — and am I even allowed to — use Meshtastic in a real-world commercial solution?

We’re living in an amazing time when it comes to access to technology. In 1992, I began studying engineering, and once I got through the heavy engineering math, I discovered a love for integrating software and hardware—or at least experimenting with it. Back then, though, things weren’t as easy or affordable. I still remember embedding Assembler into my Delphi code just to access the parallel port and turn on some LEDs.

In previous blog posts, we’ve talked about how Meshtastic operates in the ISM band, about duty cycles, and the specific frequencies in use. This time, I want to zoom out and give a broader view — not just of Meshtastic, but of the radio spectrum itself. Even though this topic isn’t directly about Meshtastic, I believe it can help us understand why we use certain frequencies — like 868 MHz — and why, for example, sending audio over Meshtastic isn’t really practical.
