What is Meshtastic? (Simple Explanation)

Meshtastic is a text-based messaging system that works totally off-grid using inexpensive LoRa radios. In this video I give an easy-to-understand overview of how it works — how multiple nodes form a mesh, how messages get forwarded between nodes, and how you use your phone over Bluetooth to connect to your node. I also cover the 915 MHz vs 868 MHz bands and the different types of devices you can use, from off-the-shelf nodes to DIY builds to all-in-one keyboard units. ⏱️ Chapters 00:00 Intro 00:13 Mesh Network 01:03 Bluetooth: Phone → Node 01:18 LoRa: Node → Node 01:44 No Internet Required 02:24 Frequencies 03:11 Node Hardware Options 04:03 Wrap Up 🔗 Official meshtastic links https://meshtastic.org https://flasher.meshtastic.org https://client.meshtastic.org 🔗 Places to buy hardware https://store.rokland.com https://atlavox.com Amazon: https://amzn.to/4qcBxY5 (Affiliate link) ---- The MostlyBuilds channel is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to amazon.com.
