ARDUINO:如何将GPS数据发送到Firebase？

        // 发送GPS数据到Firebase数据库
        String path = "/gps";
        String payload = "{\"latitude\": " + String(latitude, 6) +
                         ", \"longitude\": " + String(longitude, 6) + "}";
        Firebase.setString(firebaseData, path, payload);
        if (firebaseData.error()) {
          Serial.println("Firebase error");
        } else {
          Serial.println("Data sent to Firebase");
        }
      }
    }
