[Energia Library] RF430CL - TI NFC RF430CL330H library

hello !! 

Everything in order, it works.

now what I need to know is, can I send float type data? If so, how?

my code is : 

 

#include "NDEF.h"
#include "NDEF_TXT.h"
#include <RF430CL.h>

RF430 nfc(RF430CL330H_BOOSTERPACK_RESET_PIN, RF430CL330H_BOOSTERPACK_IRQ_PIN);

double randomDouble(double min, double max, int numCasas){
  long _min = min * pow(10, numCasas) + 0.1; 
  long _max = max * pow(10, numCasas) + 0.1;
  return (double) random(_min, _max) / pow(10, numCasas) ; 
}       

        double Freq = randomDouble(10.71, 10.79, 2)+1839755.00;
        double voltage_1 = randomDouble(0.82, 0.88, 2);
        double temperature = randomDouble(18.30, 20.00, 2);
        double vol = randomDouble(3.10, 3.29, 2);

  size_t ndef_size;

  ndef_size = Value.sendTo(nfc);                                       // Write NDEF data to NFC device memory
  nfc.setDataLength(ndef_size);                                            // Inform NFC device memory how much data is there

  Serial.println("Activating RF430CL330H RF link-");
  nfc.enable();  // Now we're live!
}

void loop() {

    }

      nfc.flush();
    }
    nfc.enable();  // If nfc.loop() returns true, it will have disabled the RF link as a side-effect.
  }

  Serial.println("<low power sleep>");

  suspend();  // Enter indefinite sleep (LPM4 on MSP430, DEEPSLEEP on ARM)
  Serial.println("<wake up>");
}

Allocate an NDEF_TXT object first instead of just composing your "Value" variable and trying to send it directly over the NFC:

NDEF_TXT t("es", Value.c_str());
int ndef_size = t.sendTo(nfc);
nfc.setDataLength(ndef_size)

Note the first string in the NDEF_TXT constructor is the language code describing the language used for the text.

Hello everyone. I've been working with the NFC module, and it worked. It sent data of an application of measures.

I have connected with the TIVA 123GXL. Today I wanted to read data, And it no longer works. Is there any way to tell if the module does not transfer data?

I connected an oscilloscope between the pins 14,15 (bridged with 9.10 respectively) of the I2C. and it show 3.2 V  in the following figure.

some help ?
