$route is not define

$route is not defined通常是在使用Vue Router时出现的错误，这是因为$route是Vue Router提供的一个全局对象，用于获取当前路由的信息。如果你在组件中使用$route对象却没有正确引入Vue Router或者没有在组件中注入router对象，就会出现这个错误。

解决这个错误的方法是，在需要使用$route的组件中正确引入Vue Router并在组件中注入router对象，例如在main.js中引入Vue Router并创建router对象：

import Vue from 'vue'
import VueRouter from 'vue-router'
import App from './App.vue'
import router from './router'

Vue.use(VueRouter)

new Vue({
  router,
  render: h => h(App)
}).$mount('#app')

然后在需要使用$route的组件中通过this.$route获取当前路由信息即可。

编写SampleApp_HandleKeys函数，处理HAL_KEY_SW_3按键事件：通过单点传送的方式，把字符串“123”发送给协调器。 #define SAMPLEAPP_SENDTOCOORD_CLUSTERID 3 afAddrType_t SampleApp_Coord_DstAddr; void SampleApp_HandleKeys( uint8 shift, uint8 keys ) { (void)shift; // Intentionally unreferenced parameter if ( keys & HAL_KEY_SW_1 ) { /* This key sends the Flash Command is sent to Group 1. * This device will not receive the Flash Command from this * device (even if it belongs to group 1). */ SampleApp_SendFlashMessage( SAMPLEAPP_FLASH_DURATION ); } //在此处添加你的代码： }

以下是SampleApp_HandleKeys函数的修改版，以处理HAL_KEY_SW_3按键事件，并通过单点传送的方式，将字符串“123”发送到协调器：

void SampleApp_HandleKeys( uint8 shift, uint8 keys )
{
  (void)shift;  // Intentionally unreferenced parameter

  if ( keys & HAL_KEY_SW_1 )
  {
    /* This key sends the Flash Command is sent to Group 1.
     * This device will not receive the Flash Command from this
     * device (even if it belongs to group 1).
     */
    SampleApp_SendFlashMessage( SAMPLEAPP_FLASH_DURATION );
  }

  // Handle HAL_KEY_SW_3 event
  if ( keys & HAL_KEY_SW_3 )
  {
    // Set destination address to coordinator
    SampleApp_Coord_DstAddr.addrMode = (afAddrMode_t)Addr16Bit;
    SampleApp_Coord_DstAddr.endPoint = SAMPLEAPP_ENDPOINT;
    SampleApp_Coord_DstAddr.addr.shortAddr = 0x0000; // Set to coordinator's short address

    // Send "123" to coordinator
    uint8 data[] = {'1', '2', '3'};
    afStatus_t status = AF_DataRequest(&SampleApp_Coord_DstAddr, &SampleApp_epDesc,
                                       SAMPLEAPP_SENDTOCOORD_CLUSTERID, sizeof(data), data,
                                       &SampleApp_TransID, AF_DISCV_ROUTE, AF_DEFAULT_RADIUS);
    if (status != afStatus_SUCCESS)
    {
      // Failed to send data
    }
  }
}

请注意，此修改版本的代码需要在其他部分调用SampleApp_SendFlashMessage函数，并且需要定义SAMPLEAPP_ENDPOINT和SampleApp_epDesc。

Cannot define multiple Listeners on the same IP:port

This error message typically occurs when you try to start multiple applications or services that are configured to listen on the same IP address and port number combination. In most cases, this is not allowed because only one application can bind to a specific IP address and port at any given time.

To resolve this issue, you will need to identify which applications or services are causing the conflict and modify their configuration settings to listen on different IP addresses or port numbers. Alternatively, you can configure a reverse proxy to route traffic between the conflicting applications or services, allowing them to coexist on the same IP address and port.

It is important to note that changing the configuration settings of an application or service should be done with caution, as it could impact the performance and functionality of the application or service. Always make sure to test any changes in a non-production environment before implementing them in a production environment.
