how to display integer value on putty using uart?

[Liverpool007]

i was using the serial example in examples/peripheral/serial and i Want to display integer value int i=1234 on the serial terminal(putty).I want to convert the int value to string.

if i use it in the serial program it is not working.

.

int main(void)
{
    ret_code_t ret;
    ret_code_t ret1;
    

    ret = nrf_drv_clock_init();
    APP_ERROR_CHECK(ret);
    ret = nrf_drv_power_init(NULL);
    APP_ERROR_CHECK(ret);

    nrf_drv_clock_lfclk_request(NULL);
    ret = app_timer_init();
    APP_ERROR_CHECK(ret);

    bsp_board_leds_init();
    bsp_board_buttons_init();

    ret = nrf_serial_init(&serial_uart, &m_uart0_drv_config, &serial_config);
    APP_ERROR_CHECK(ret);

     char *tx_message ;
     int i = 12345;
    tx_message = change(i);

    ret = nrf_serial_write(&serial_uart,
                           tx_message,
                           strlen(tx_message),
                           NULL,
                           NRF_SERIAL_MAX_TIMEOUT);
    printf("%d",i);
    APP_ERROR_CHECK(ret);
   
   

   

    while (true)
    {
/*        char c;
        ret = nrf_serial_read(&serial_uart, &c, sizeof(c), NULL, 1000);
        if (ret != NRF_SUCCESS)
        {
            continue;
        }
        (void)nrf_serial_write(&serial_uart, &c, sizeof(c), NULL, 0);
        (void)nrf_serial_flush(&serial_uart, 0);

*/    ret = nrf_serial_write(&serial_uart,
                           tx_message,
                           strlen(tx_message),
                           NULL,
                           NRF_SERIAL_MAX_TIMEOUT);
    // printf("%d",i);
     ret = nrf_serial_write(&serial_uart,
                           "\n\r",
                           strlen(tx_message),
                           NULL,
                           NRF_SERIAL_MAX_TIMEOUT);
     (void)nrf_serial_flush(&serial_uart, 0);
      
      nrf_delay_ms(2000);
     APP_ERROR_CHECK(ret);
    }
}
