Heltec Meshtastic Application Example



You need to flash the meshtastic firmware yourself

Summary

The Heltec ESP32 LoRa Series is now fully compatible with Meshtastic, which means that our customers can choose from this option and benefit from the open source Mesh network. Meshtastic is a community-driven and open-source project that allows the use of affordable LoRa radios for long-range off-grid communication in areas without any existing or reliable communication infrastructure.

Heltec ESP32+LoRa Series supports the following development methods:



Heltec ESP32+LoRa Series is compatible with the following open-source projects:

  • ...

We also provide a standard ESP32 Arduino LoRaWAN library:

This library is already included in the by default.
