Serial attach with Nucleo L432KC doesn't work

This code says hello but never stop blinking when one char is sent to Nucleo L432KC

1. include "mbed.h"

1. define TX_PIN USBTX
2. define RX_PIN USBRX
3. define BRATE 921600
4. define LED_PIN LED0
5. define TOGGLE_RATE (0.5f)
6. define BUFF_LENGTH 4

Serial test_connection(USBTX, USBRX,BRATE);

volatile bool blinking = true;

DigitalOut LED(LED1); uint8_t rx_buf[BUFF_LENGTH + 1];

void blink(void) { if (blinking) { LED = !LED; } }

void serialCb() {

blinking = false; rx_buf[0] = test_connection.getc(); test_connection.write(rx_buf, 1, 0, 0); }

int main() { wait(5.0); test_connection.attach(&serialCb);

test_connection.printf("hello\n"); while (0==0) { blink(); wait(1.0); } }
