Imagine this: you need to track 40 athletes in real-time over a 250 km distance in the mountains, where there isn't a single cell tower in sight. That was the exact challenge I faced at the RusXFly paragliding race. In this article, I'll tell you how we solved it with LoRa, Heltec modules, and a whole lot of enthusiasm.
On October 5, 2025– A significant communications experiment took place on the island of La Réunion in the Indian Ocean. The Gaulix network, a local communication system based on the Meshtastic open-source protocol and LoRa technology, successfully completed its first large-scale island-wide test.
Designed to provide a vital information lifeline for residents when traditional networks fail during extreme weather events such as hurricanes, the initiative represents a major step towards community resilience. Heltec, a provider of LoRa devices and Lora solutions, proudly supported this visionary community-led project with its hardware and technical expertise.
This Thanksgiving, we want to express our heartfelt gratitude to all our amazing customers and community members.
May your holiday be filled with warmth, laughter, and cherished moments with friends and family.
Thank you for being part of the Heltec family — your support inspires us to innovate and create every day!
Shenzhen, China – November 15–16, 2025 – The Heltec team recently attended Maker Faire Shenzhen 2025, one of Asia’s most influential gatherings for makers, innovators, and technology enthusiasts. The event brought together hundreds of exhibitors from across the globe, showcasing advancements in robotics, AI, embedded systems, sensing technologies, and next-generation hardware.
To meet the growing demand for long-range, high-speed, and stable wireless communication in Internet of Things (IoT) applications, we proudly introduce the HC-02 Wi-Fi HaLow Transparent Transmission Module.
Powered by the advanced ESP32-S3 and MM6108Q chipsets, this module offers exceptional processing capability and can be directly controlled via UART AT commands—no SDK development required.
In Chengdu, November 2025 —The four-day 11th IEEE World Forum on Internet of Things (IEEE WF-IoT 2025), held October 27–30 in Chengdu, SiChuan Province, concluded successfully. Under the theme “Smart and Sustainable IoT,” the forum brought together IoT experts, industry representatives and practitioners from around the world. As a Chengdu-headquartered provider of IoT devices and integrated solutions, Heltec participated actively in the forum and returned with important insights across three dimensions: trend capture, field validation and channel engagement.
Innovation isn't just a technological issue, but a social and cultural shift. Maker Faire Rome makes innovation accessible and enjoyable to all, a showcase of passion. Being there was a deeply rewarding experience, made possible thanks to the Italian Radio Amateurs Association (Associazione Radioamatori Italiani), club of Roma Capitale APS, which for the third consecutive year presented a valuable project: "OFF-GRID radio communications, the radio always works."
Recently, some users have expressed concerns about LoRa 32 V4 receiver sensitivity. Let me tell you the conclusion first: Don't worry, compared with V3, V4 performs better both in receiver and transmission.
This article will demonstrate this through both communication principles and experiments.
Fork Heltec Wi-Ki repository, and clone the forked project into local. Copy the contest-content-template file in the news folder, rename it into your project name, lowercase, spaces are replaced by -.
Enter the folder and change the name of "contest-content-template.md" to the same as the parent directory.
