I need a small hybrid mobile app built with React Native that connects to a given MQTT broker, parses the incoming JSON payload I’ll supply, and shows each message on-screen in real time. Here’s what I’m after: • A straightforward text panel—no pop-ups or interactive lists—where every new message appears immediately beneath the previous one. • Each message line should use different colours based on the message type contained in the JSON. • Display the message body together with its timestamp (taken from the payload or the broker, whichever is easier). I will share the exact JSON schema, topic(s), broker URL, and sample traffic as soon as we start. As long as the code runs on both Android and iOS simulators and is clear enough for me to tweak colours or fonts later, I’ll be happy. Please return the full React Native source, a brief README with setup steps (broker credentials, required npm packages, and how to build/run), and any notes on libraries you choose for MQTT (e.g., mqtt.js, react-native-mqtt).
