virtual wire multiple values

Using Arduino Programming Questions
11

With tips & trucks from all of you at least i have a code which is working (completed with a DHT11 sensor):

Sender:

#include <VirtualWire.h>
#include <DHT.h>

#define DHTPIN 2

#define DHTTYPE DHT11

DHT dht(DHTPIN, DHTTYPE);

void setup()
{
  Serial.begin(9600);
  Serial.println("setup");
  vw_set_tx_pin(12);
  vw_setup(2000);
  pinMode(13,OUTPUT);
  dht.begin();
}
void loop()
{
  int h = dht.readHumidity();
  int t = dht.readTemperature();

  String messageString = String();
  for(int i=0;i<6;i++){
    messageString.concat(analogRead(i));
    messageString.concat(",");
  }
  messageString.concat(t);
  messageString.concat(",");
  messageString.concat(h);
  messageString.concat(",");

  char msg[messageString.length()+1];
  messageString.toCharArray(msg,messageString.length()+1);
  digitalWrite(13, true);
  vw_send((uint8_t *)msg, strlen(msg));
  vw_wait_tx();
  digitalWrite(13, false);
  delay(1000);
}

Reciever:

#include <VirtualWire.h>
void setup()
{
     Serial.begin(9600);
    Serial.println("setup");
    Serial.println("CLEARDATA");
    vw_setup(2000);
    vw_set_rx_pin(11);
    vw_rx_start();
    pinMode(13,OUTPUT);
}
void loop()
{
    uint8_t buf[VW_MAX_MESSAGE_LEN];
    uint8_t buflen = VW_MAX_MESSAGE_LEN;
    if (vw_get_message(buf, &buflen)) 
    {
int i;
digitalWrite(13, true); 
//Serial.print("Got:   ");
Serial.println("CLEARDATA");
Serial.print("DATA, ,");
for (i = 0; i < buflen; i++)
{
  
    Serial.write(buf[i]);
    Serial.print(" ");
}
Serial.println(" ");

     digitalWrite(13, false);
    }
}

The concat-function works fine for me.
The CLEARDATA and DATA prints are necessary for the transport to Excel.

Thanks so far...
