INTERRUPTS ENABLED AND DISABLED SERIAL

hi, i try to disabled an interrupt befores using it, after that i printf datas i want and after all of this i enabled again the interrupt, and the process repeat.(DISABLED, PRINTF, ENABLED)

BUT I CAN'T DISABLED THIS

IT CAN'T CONTROL THEM

THIS IS THE CODE

1. include "mbed.h"

DigitalOut led1(LED1); DigitalOut led2(LED2); DigitalOut led3(LED3); DigitalOut led4(LED4);

Serial imu(p13, p14);

Serial xbee(p9,p10);

Serial pc(USBTX,USBRX);

void imurx_interrupt();

char rx_imu[218];

int m;

int aux2;

int aux;

int main(){

imu.baud(38400);

xbee.baud(9600);

pc.baud(9600);

imu.attach(&imurx_interrupt, Serial::RxIrq);

NVIC_EnableIRQ(UART1_IRQn);

NVIC_EnableIRQ(UART2_IRQn);

NVIC_EnableIRQ(UART3_IRQn);

m=1; aux=4;

while(1){

pc.printf("LAZO PIRNCIPAL\n\n");

led1=1;

wait_ms(20);

for (int i=0; i<220; i++) {

led4=!led4;

xbee.printf("%c",rx_imu[i]);

pc.printf("%c",rx_imu[i]);

if(i==218){

m=1;

pc.printf("SE IMPRIMIO EN EL LAZO PRINCIPAL\n\n");

NVIC_EnableIRQ(UART2_IRQn);

NVIC_EnableIRQ(UART3_IRQn);

} }

led1=0; } }

void imurx_interrupt(){

if(m==1){

if(imu.readable()&&(aux==4)){

led2=!led2;

wait_ms(5);

aux=4;

imu.gets(rx_imu,220);

pc.printf("ESTOY DENTRO:\n");

pc.printf("\n");

for (int i=0; i<220; i++) {

led3=!led3;

xbee.printf("%c",rx_imu[i]);

pc.printf("%c",rx_imu[i]);

if(i==218){

m=1;

pc.printf("SALI\n\n");

} }

aux2=3;

NVIC_DisableIRQ(UART2_IRQn);

NVIC_DisableIRQ(UART3_IRQn);

} } }
