This is my code

#include <stdio.h>
#include <string.h>
#include "lpc17xx_pinsel.h"
#include "lpc17xx_gpio.h"
#include "lpc17xx_i2c.h"
#include "lpc17xx_ssp.h"
#include "lpc17xx_timer.h"
#include "lpc17xx_uart.h"

#include "led7seg.h"
#include "pca9532.h"
#include "acc.h"
#include "oled.h"
#include "light.h"
#include "temp.h"

static char* msg = NULL;

void pinsel_uart3(void){
PINSEL_CFG_Type PinCfg;
PinCfg.Funcnum = 2;
PinCfg.Pinnum = 0;
PinCfg.Portnum = 0;
PINSEL_ConfigPin(&PinCfg);
PinCfg.Pinnum = 1;
PINSEL_ConfigPin(&PinCfg);
}

void init_uart(void){
UART_CFG_Type uartCfg;
uartCfg.Baud_rate = 115200;
uartCfg.Databits = UART_DATABIT_8;
uartCfg.Parity = UART_PARITY_NONE;
uartCfg.Stopbits = UART_STOPBIT_1;
//pin select for uart3;
pinsel_uart3();
//supply power & setup working par.s for uart3
UART_Init(LPC_UART3, &uartCfg);
//enable transmit for uart3
UART_TxCmd(LPC_UART3, ENABLE);
}

int main (void){
uint8_t data = 0;
uint32_t len = 0;
uint8_t line[64];
init_uart();
//test sending message
msg = "Welcome\r\n";
UART_Send(LPC_UART3, (uint8_t *)msg , strlen(msg), BLOCKING);
//test receiving a letter and sending back to port
UART_Receive(LPC_UART3, &data, 1, BLOCKING);
UART_Send(LPC_UART3, &data, 1, BLOCKING);
//test receiving message without knowing message length
len = 0;
do
{ UART_Receive(LPC_UART3, &data, 1, BLOCKING);
if (data != '\r')
{
len++;
line[len-1] = data;
}
} while ((len<64) && (data != '\r'));
line[len]=0;
UART_SendString(LPC_UART3, &line);
printf("--%s--\n", line);
while (1);
return 0;
}

I am able to receive the message - Welcome on Tera term buy I try pressing any keys , there is no signal at all . May I know where gone wrong? It is able to work in a wire communication (able to send and receive) but not in wireless communication
