CC1101 communication issues

Hi, I just started trying to send data through a CC1101 using this library here --> GitHub - simonmonk/CC1101_arduino: A clone of the ELECHOUSE_CC1101 http://www.elechouse.com library updated for Arduino 1.0 plus.

I want to transmit two 6 digit numbers at every loop, for example, "12.123456 12.6754322". But I am having issues understanding the data types that are required since the library's documentation is not extensive.

I modified the example code like this:

#include <ELECHOUSE_CC1101.h>

const int n = 61;

byte stringToByte(char * src){
    return byte(atoi(src));
}

void setup() {
  Serial.begin(9600);
  ELECHOUSE_cc1101.Init(F_433); // set frequency - F_433, F_868, F_965 MHz
}

void loop() {
  char Lat[]= "12.123456 12.6754322";
  byte buffer = stringToByte(Lat);
  int len = sizeof(buffer);
  if (Serial.available()) {    
    ELECHOUSE_cc1101.SendData(buffer, len);
  }
}

The code compiles, but my receiver does not appear to see anything. My intention was to take a char array and convert it into an array of bytes which seems to be the data format that is then transmitted. Am I missing something?

As recieve code, I am using:

  
#include <ELECHOUSE_CC1101.h>

const int n = 61;

void setup()
{
  Serial.begin(9600);
  Serial.println("Rx");
  ELECHOUSE_cc1101.Init(F_433);  // set frequency - F_433, F_868, F_965 MHz
  ELECHOUSE_cc1101.SetReceive();
}

byte buffer[61] = {0};

void loop()
{
  if (ELECHOUSE_cc1101.CheckReceiveFlag())
  {
    int len = ELECHOUSE_cc1101.ReceiveData(buffer);
    buffer[len] = '\0';
    Serial.println((char *) buffer);
    ELECHOUSE_cc1101.SetReceive();
  }
}

Thanks
