TL;DR
Hackaday has released a new firmware update for the Communicator badge, adding Meshtastic support and improved battery management. The upgrade aims to extend the badge’s functionality and lifespan beyond events.
Hackaday has released a new firmware for its Communicator badge, enabling support for Meshtastic and longer battery life for the GPS module. The update aims to extend the badge’s usability beyond the event setting, transforming it into a more versatile device.
The Communicator badge, a handheld gadget featuring a QWERTY keyboard, LoRa radio, and ESP32 microcontroller, originally debuted at a recent event in Europe. Its initial firmware included a simple messaging app built with MicroPython, which proved popular among attendees. The new firmware, developed by an anonymous hacker, introduces support for Meshtastic, an open-source mesh communication protocol, allowing the badge to connect with other Meshtastic devices and extend its communication range.
Additionally, the firmware improves battery management for the GPS module, supporting longer operation times. Installation requires the ESP-IDF development environment, but comprehensive instructions are provided. The firmware runs on FreeRTOS, a real-time operating system, which is notable for its potential to give the badge a more durable, ongoing role after the event concludes. Hackaday emphasizes that the badge’s physical design has significant potential, and this firmware unlocks new use cases in the field.
Enhanced Functionality Extends Badge’s Usefulness
This firmware update significantly enhances the Communicator badge’s capabilities, transforming it from a temporary event gadget into a practical communication device with real-world applications. Support for Meshtastic opens the door for decentralized mesh networks, which can be useful in emergency situations or remote areas. Longer battery life for GPS expands its potential for outdoor use, making it more than a novelty item.
By leveraging FreeRTOS, the badge gains a more robust operating environment, which could lead to further customizations and integrations. This development underscores the importance of open hardware and firmware in extending the lifespan and utility of DIY electronics, reducing e-waste, and fostering community-driven innovation.

From Event Gadget to Real-World Tool
The Hackaday Communicator badge was first introduced as a stylish handheld device with messaging capabilities built into its MicroPython firmware. Its design, featuring a QWERTY keyboard and LoRa radio, made it popular at the recent European event, where attendees appreciated its form factor and basic functionality. However, the initial firmware was limited to simple messaging, with no support for mesh networking or extended outdoor use.
In response, a developer created a new firmware that integrates support for Meshtastic—an open-source protocol enabling mesh communication—allowing the badge to connect with other devices and operate in more complex network environments. The firmware also improves battery management, especially for the GPS module, addressing the device’s power consumption issues during outdoor activities. The update is part of a broader trend of repurposing event gadgets into more durable, versatile tools through software modifications.
“This firmware unlocks the badge’s potential for real-world use, beyond just being a temporary event device.”
