想实现一个按键发送MQTT消息功能，MQTT收发测试已经没有问题，按键按下后中断函数也可以正常打印，但是无法再按键按下后任务函数中发送MQTT消息，一直报错
IO中断部分代码
/**
* GPIO中断部分
*/
sta
tic xQueueHandle gpio_evt_queue = NULL;
static void IRAM_ATTR gpio_isr_handler(void* arg)
{
uint32_t gpio_num = (uint32_t) arg;
xQueueSendFromISR(gpio_evt_queue, &gpio_num, NULL);
}
/**
* 按键处理函数
*/
int last_time = 0;
static void key_task(void* arg)
{
uint32_t io_num;
for(;;) {
if(xQueueReceive(gpio_evt_queue, &io_num, portMAX_DELAY)) {
// printf("GPIO[%d] intr, val: %dn", io_num, gpio_get_level(io_num));
int now = xTaskGetTickCountFromISR();
if(gpio_get_level(io_num) == 1){ //高电平 判断短按还是长按
//获取系统当前运行的时钟节拍数,此函数用于在中断服务程序里面调用， 如果在任务里面调用的话，需要使用函数 xTaskGetTickCount，这两个函数切不可混用
if (now - last_time > MIN_DELAY) { //长按
printf("long %d %dn", now, last_time);
gpio_set_level(3, 0);
//长按业务逻辑
}else if (now - last_time < 5){ //消抖 无操作
}else{ //短按
printf("short %d %dn", now, last_time);
gpio_set_level(3, 1);
//短按业务逻辑 上报
// char topic_init[64];
// sprintf(topic_init, "/c/%s/send", mqtt_user);
if(client){
esp_mqtt_client_publish(client, '/test', "find", 0, 1, 0); //这行有问题,执行后重启
printf("send okn");
}else{
printf("no client");
}
// ESP_LOGI(TAG, "sent publish successful, msg_id=%d", msg_id);
}
}else{ //低电平 按下按键
}
last_time = now;
}
}
}
