I solved the error. This code was enough to read and send the file. I am sharing it here to help other friends. Good luck with..

    FIL fil;        /* File object */
    char line[244]; /* Line buffer */
    FRESULT fr;     /* FatFs return code */

 fr = f_open(&fil, "file.txt", FA_READ);
    if (fr) return (int)fr;

    /* Read every line and display it */
    while (f_gets(line, sizeof line, &fil)) {
        nrf_delay_ms(5);
        printf(line);
    }

   f_close(&fil);
