This did the trick.
gw.send(msg.set(readString.c_str()));
Thanks for this

Hello

I dont get any error when i compile, so i will make a test later today.

Thanks
Andreas H

Opps . i missed that in this sketch

But the main problem is howto send a string och many chars

Thanks
Bu ti don't know how to fix this in my sketch , can you please point me to the right direction ??

Hello

I have play with my sensors a lot and it works perfect (only try standard sensors).
But now i want to create a sensor that read/write on the serial port (pin 0 and 1) and send it to the gateway
My C skills are very low but i try to learn

This is my sketch:

#include <SPI.h>
#include <MySensor.h>  


#define CHILD_ID 0
String readString;

MySensor gw;
MyMessage msg(CHILD_ID,V_VAR1);

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

  // Send the sketch version information to the gateway and Controller
  gw.sendSketchInfo("test", "1.0");

  // Register all sensors to gateway (they will be created as child devices)
  gw.present(CHILD_ID, S_CUSTOM);
}

void loop()   
{
	
  while (Serial.available()) {
    delay(3);  //delay to allow buffer to fill 
    if (Serial.available() >0) {
      char c = Serial.read();  //gets one byte from serial buffer
      readString += c; //makes the string readString
    } 
  }

  if (readString.length() >0) {
      Serial.println(readString); //see what was received

	  gw.send(msg.set(readString));
	  readString="";
    
  } 
}

The string from serial port looks like this: "4. ERO 11421"

But when i verify the sketch in codebender i get this error:

Test_sensor.ino:69:16: error: no matching member function for call to 'set'
gw.send(msg.set(readString));
~~^

Any idea how to fix this

Thanks Andreas
