using sprint

I would like to use the Record text message to include variables using sprintf as shown below, but even thou it compiles and uploads, fails to write record. Is this not possible or a bug?

To see full issue are arduino forum go here

char buffer[40]; int days = 3; sprintf(buffer,"Days user has taken their medication = %d", days); tag.writeNDEFText(buffer, &memLoc, false, true); // MB=0, ME=1

The following code works for me:

int parte_entera = (int) temperatura_celsius;

int parte_decimal = (int) ((temperatura_celsius - parte_entera) * 100);

sprintf(mensaje,"Temperatura = %d.%d", parte_entera,parte_decimal);

uint16_t memLoc = tag.getCCFileLen();

tag.writeNDEFText(mensaje, &memLoc, true, true); // MB=1, ME=1

Serial.println("Temperatura actualizada correctamente");
