Little Relay

Little Relay is an open-source Android application for moving data between BLE equipment and systems that use MQTT. It works as a bridge between nearby BLE devices and an MQTT broker. Data can travel from BLE toward MQTT, allowing information from BLE-connected equipment to reach MQTT-based systems. Data can also travel from MQTT toward BLE, supporting communication in the opposite direction.

The application is intended for users who work with Android devices, BLE-connected equipment, or MQTT-based systems that need these communication methods to exchange data. Its central function is connecting BLE and MQTT rather than offering a broader collection of unrelated tools. The two-way design makes the Android device an intermediary between the connected equipment and the MQTT environment. As open-source software, Little Relay can be examined and used according to the terms of its license.

Little Relay is listed in the Internet & Browsers category because its purpose involves communication between networked MQTT systems and nearby BLE equipment. It is built for the Android platform, so its catalog placement identifies Android as the target platform. MirrorNest distributes the official build by mirroring it directly on its own storage. Before publication, the mirrored file is scanned for malware, giving users a catalog-based way to download the official build.
