Arduino Uno with HDC1008-Sensor: Thingworx receives no data

I have tried for many hours to send data from the Arduino with HDC1008-Sensor (Temperature, Humidity) but at last i dont get any further. I tried to adjust the Weather App with Arduino Uno Project. The Thing is a Generic Thing and the properties (Temp, Humid) are from type Number.

I have created one Service:

The adjusted Code for the Arduino:

#include <HDC100X.h>
#include <Wire.h>
#include <SPI.h>
#include <WiFi101.h>

//How many values you will be pushing to ThingWorx
#define propertyCount 2

// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local Network:

char server[] = "192.168.2.105";

char ssid[] = "xxxxxx";          //  your network SSID (name)
char pass[] = "xxxxxx";   // your network password
int status = WL_IDLE_STATUS;
WiFiClient client;

//ThingWorx App key which replaces login credentials)
char appKey[] = "d9e8e9de-f548-43e0-aeaa-2b9c6847c7dc";
// ThingWorx Thing name for which you want to set properties values
char thingName[] = "SteamSensor2";
//Interval of time at which you want the properties values to be sent to TWX server
int timeBetweenRefresh = 5000;
// ThingWorx service that will set values for the properties you need
// See the documentation for this tutorial for more information
char serviceName[] = "SetTempAndHumid";

//Initialize Properties Names and Values Arrays
char* propertyNames[] = {"Temp", "Humid"};
double propertyValues[propertyCount];

// last time you connected to the server, in milliseconds
unsigned long lastConnectionTime = 0;
// state of the connection last time through the main loop
boolean lastConnected = false;

//Initialize an HTU21D library object to read
// temperature and humidity data from your connected sensor
HDC100X hdc(0x43);

void setup() {
   
  // start serial port:
 
  Serial.begin(9600);
  while (!Serial) {
    ; // wait for serial port to connect. Needed for Leonardo only
  }
  //initialize HTU21D object to read values from sensors
   hdc.begin(HDC100X_TEMP_HUMI,HDC100X_14BIT,HDC100X_14BIT,DISABLE);

   Serial.println("Attempting to connect to WPA network...");
  Serial.print("SSID: ");
  Serial.println(ssid);

  status = WiFi.begin(ssid, pass);
  if ( status != WL_CONNECTED) {
    Serial.println("Couldn't get a wifi connection");
    // don't do anything else:
    while(true);
  }
  else {
    Serial.println("Connected to wifi");
    Serial.println("\nStarting connection...");
    // if you get a connection, report back via serial:
    if (client.connect(server, 80)) {
      Serial.println("connected1");
    }
  }
}

void loop() {

  // Aquire sensor values
  propertyValues[0] = hdc.getTemp();
  propertyValues[1] = hdc.getHumi();

  // wait the established interval of time before
  // reading values from the sensor
  // and sending them to the TWX server again
  // delay(timeBetweenRefresh);
  if (millis() - lastConnectionTime > timeBetweenRefresh) {
    updateValues(propertyValues, client, server, appKey, thingName, serviceName, propertyNames);
  }
}

void updateValues(double values[] , WiFiClient &client, char server[], char appKey[], char thingName[], char serviceName[], char* sensorNames[])
{
  //build the String with the data that you will send
  //through REST calls to your TWX server
  char data[80];
  strcpy(data, "?appKey=");
  strcat(data, appKey);
  strcat(data, "&method=post&x-thingworx-session=true");
  // if you get a connection, report back via serial:
  if (client.connected()) {
    Serial.println("connected2");
    // send the HTTP POST request:
    client.print("POST /Thingworx/Things/");
    client.print(thingName);
    client.print("/Services/");
    client.print(serviceName);
    client.print(data);
    client.print("<");
    for (int idx = 0; idx < propertyCount; idx++)
    {
      client.print("&");
      client.print(propertyNames[idx]);
      client.print("=");
      client.print(propertyValues[idx]);
    }
    client.print(">");
    client.println(" HTTP/1.1");
    client.print("Host: ");
    client.println(server);
    client.println("Content-Type: text/html");
    client.println();

     //client.stop();
    lastConnectionTime = millis();
   
    // print the request out
    Serial.print("POST /Thingworx/Things/");
    Serial.print(thingName);
    Serial.print("/Services/");
    Serial.print(serviceName);
    Serial.print(data);
    Serial.print("<");
    for (int idx = 0; idx < propertyCount; idx++)
    {
      Serial.print("&");
      Serial.print(propertyNames[idx]);
      Serial.print("=");
      Serial.print(propertyValues[idx]);
    }
    Serial.print(">");
    Serial.println(" HTTP/1.1");
    Serial.print("Host: ");
    Serial.println(server);
    Serial.println("Content-Type: text/html");
    Serial.println();

}
  else {
    // kf you didn't get a connection to the server:
    Serial.println("the connection could not be established");
    client.stop();
  }
}

The generated Serial-Output:

Attempting to connect to WPA network...
SSID: xxxx
Connected to wifi

Starting connection...
connected1
connected2
POST /Thingworx/Things/SteamSensor2/Services/SetTempAndHumid?appKey=d9e8e9de-f548-43e0-aeaa-2b9c6847c7dc&method=post&x-thingworx-session=true<&Temp=24.45&Humid=32.41> HTTP/1.1
Host: 192.168.2.105
Content-Type: text/html

And I tried the HTTP-Request Manual what ended up like this:

for: http://192.168.2.105/Thingworx/Things/SteamSensor2/Services/SetTempAndHumid?appKey=d9e8e9de-f548-43e0-aeaa-2b9c6847c7dc&method=post&x-thingworx-session=true<&Temp=24.40&Humid=32.21>

I think that the Arduino has established a Connection to my local ThingWorx Server, but I have not found any proof for this like a log-file.

Because of the "Unable To Convert From Java.lang.String to NUMBER"-Advice I changed the Base-Type of the Properties to String, but the message was still the same.

Next I added to the Service "parseFloat", but there is still the same Problem.
