eMQTT5 is a MQTT v5.0 client for embedded CPU with minimal binary usage and high performance.
BwareArea is an Android application for Point-Of-Interest (POI) tracking that works offline and can be used to display a warning when approaching, monitoring speed on an overlay (so you can still use your favorite map software). Typically used for speedcam and danger zone detection.
