ESP32 Integration Guide

The ESP32 is a powerful, low-cost microcontroller that's ideal for medical device integration with Medibound. This guide will walk you through setting up and implementing the Medibound ESP32 library.

Prerequisites​

  • ESP32 development board
  • Arduino IDE or PlatformIO
  • Medibound account and API credentials
  • Basic understanding of C++ and embedded systems

Installation​

  1. Add the Medibound ESP32 library to your project:

    #include <MediboundESP32.h>

  2. Configure your development environment:

    • Install the ESP32 board support package
    • Set up your WiFi credentials
    • Configure your Medibound API credentials

Basic Implementation​

Here's a basic example of implementing the Medibound ESP32 library:

#include <MediboundESP32.h>
#include <WiFi.h>

// Initialize the Medibound client
MediboundESP32 medibound;

// WiFi credentials
const char* ssid = "YOUR_WIFI_SSID";
const char* password = "YOUR_WIFI_PASSWORD";

// Medibound credentials
const char* apiKey = "YOUR_API_KEY";
const char* deviceId = "YOUR_DEVICE_ID";

void setup() {
  Serial.begin(115200);
  
  // Connect to WiFi
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  
  // Initialize Medibound
  medibound.begin(apiKey, deviceId);
}

void loop() {
  // Send sensor data
  float temperature = readTemperature();
  medibound.sendData("temperature", temperature);
  
  // Check for commands
  if (medibound.hasCommand()) {
    String command = medibound.getCommand();
    processCommand(command);
  }
  
  delay(1000);
}

Key Features​

1. Real-time Data Transmission​

  • Secure MQTT connection for real-time data streaming
  • Automatic reconnection handling
  • Data buffering for offline operation

2. Device Management​

  • Automatic device registration
  • OTA (Over-The-Air) updates
  • Configuration management

3. Security​

  • TLS/SSL encryption
  • Secure credential storage
  • Authentication and authorization

Advanced Usage​

Custom Data Types​

// Define custom data structure
struct SensorData {
  float temperature;
  float humidity;
  int pressure;
};

// Send custom data
SensorData data = {25.5, 60.0, 1013};
medibound.sendCustomData("sensor_readings", data);

Event Handling​

void onConnectionLost() {
  // Handle connection loss
}

void onCommandReceived(String command) {
  // Process incoming commands
}

// Register callbacks
medibound.onConnectionLost(onConnectionLost);
medibound.onCommandReceived(onCommandReceived);

Best Practices​

  1. Error Handling

    • Always implement proper error checking
    • Use try-catch blocks for critical operations
    • Implement fallback mechanisms

  2. Power Management

    • Use deep sleep when possible
    • Implement power-saving features
    • Monitor battery levels

  3. Data Management

    • Implement data validation
    • Use appropriate sampling rates
    • Buffer data when offline

Troubleshooting​

Common issues and solutions:

  1. Connection Issues

    • Check WiFi credentials
    • Verify API credentials
    • Ensure proper network configuration

  2. Data Transmission Problems

    • Check payload size
    • Verify data format
    • Monitor memory usage

  3. Performance Issues

    • Optimize sampling rates
    • Reduce payload size
    • Implement proper buffering
