Need to check JSON serialization

JSON serializer

This project demonstrates how to serialize and deserialize WAMP messages on an ESP32 using the ArduinoJson library. It provides simple methods to convert WAMP messages into JSON format

Open Arduino IDE.

Go to Sketch -> Include Library -> Manage Libraries...
Search for "ArduinoJson by Benoit" and install the latest version.
Create new Sketch and copy the code.

#include <ArduinoJson.h>

// Define a basic WAMP Message structure for demonstration.
struct WAMPMessage {
    int type;
    const char* message;

    void marshal(JsonDocument& doc) const {
        doc["type"] = type;
        doc["message"] = message;
    }

    void unmarshal(const JsonDocument& doc) {
        type = doc["type"];
        message = doc["message"];
    }
};

// Function to serialize a WAMP message
String serializeWAMPMessage(const WAMPMessage& wampMessage) {
    StaticJsonDocument<200> doc;
    wampMessage.marshal(doc);

    String output;
    serializeJson(doc, output);
    return output;
}

// Function to deserialize a WAMP message from JSON
WAMPMessage deserializeWAMPMessage(const String& data) {
    StaticJsonDocument<200> doc;
    deserializeJson(doc, data);

    WAMPMessage wampMessage;
    wampMessage.unmarshal(doc);
    return wampMessage;
}

void setup() {
    Serial.begin(115200);
}

void loop() {
    // Main loop logic here
        // Example WAMP message
    WAMPMessage messageToSend;
    messageToSend.type = 1;
    messageToSend.message = "Hello, WAMP!";

    // Serialize the message
    String serialized = serializeWAMPMessage(messageToSend);
    Serial.println("Serialized message: ");
    Serial.println(serialized);

    // Deserialize the message
    WAMPMessage receivedMessage = deserializeWAMPMessage(serialized);
    Serial.println("Deserialized message: ");
    Serial.printf("Type: %d, Message: %s\n", receivedMessage.type, receivedMessage.message);
}

Connect your ESP32, upload the code and you’ll see the serialized and deserialized WAMP message printed to the serial monitor.
