#include <ArduinoJson.h>

void setup() {
  // Initialize serial port
  Serial.begin(9600);
  while (!Serial)
    continue;

  // Allocate the JSON document
  JsonDocument doc;

  // JSON input string.
  const char* json =
      "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";

  // Deserialize the JSON document
  DeserializationError error = deserializeJson(doc, json);

  // Test if parsing succeeds
  if (error) {
    Serial.print(F("deserializeJson() failed: "));
    Serial.println(error.f_str());
    return;
  }

  // Fetch the values
  //
  // Most of the time, you can rely on the implicit casts.
  // In other case, you can do doc["time"].as<long>();
  const char* sensor = doc["sensor"];
  long time = doc["time"];
  double latitude = doc["data"][0];
  double longitude = doc["data"][1];

  // Print the values
  Serial.println(sensor);
  Serial.println(time);
  Serial.println(latitude, 6);
  Serial.println(longitude, 6);

// The book "Mastering ArduinoJson" contains a tutorial on deserialization.
// It begins with a simple example, like the one above, and then adds more
// features like deserializing directly from a file or an HTTP request.
