Cloud & IoT Integration Guide
Overview
This guide describes how to connect the device to a cloud platform or IoT service for remote monitoring, data synchronization, and device management.
Prerequisites
* Device running Android 13 or above * Stable Wi-Fi or 4G/5G network connection * Developer account on supported IoT cloud platform (e.g., AWS IoT, Azure IoT Hub, Alibaba Cloud IoT)
Integration Steps
1. **Obtain device credentials** * **8000 mAh (typical)** * Supports up to **8–10 hours** of continuous usage (depending on workload)
2. **Configure MQTT client** * Install MQTT client library (e.g., Paho MQTT for Java) * Configure endpoint, port, and authentication parameters
3. **Establish secure connection** * Use TLS 1.2 for encrypted communication * Validate server certificates to prevent MITM attacks
4. **Publish & Subscribe** * Publish telemetry data (battery, location, sensor values) * Subscribe to remote control topics (e.g., restart, config update)
Sample Code
```java
MqttClient client = new MqttClient("ssl://iot.example.com:8883", clientId);
MqttConnectOptions options = new MqttConnectOptions();
options.setUserName("device123");
options.setPassword("mySecret".toCharArray());
client.connect(options);
client.publish("device/telemetry", new MqttM
Verification
* Confirm data appears in cloud console * Test sending remote commands from IoT platform to device
Notes
* Ensure device clock is synchronized (NTP) to avoid TLS handshake errors * Avoid frequent data publishing that may exceed cloud platform limits
