使用ESP32C3和S3系列芯片共60个，mesh-lite组网，然后通过MQTT收发数据，串口打印错误日志
设备mesh组网中而且获取到IP,但是通讯失败。

sometime this problem also happen with me, hope this problem fix =((

将设备减少至30-40，设备可以重新组网，并进行MQTT双向通信

如果设备布置的比较集中，超过三四十个设备是会出现应用层链接断开之类的问题，主要是因为设备都处于同一个信道，信道拥堵导致 Wi-Fi 数据帧发送不了，从而造成应用层链接断开。

有两个建议：

  1. 适当将设备布置的分散一些，减小设备间的无线干扰
  2. 设当增大 beacon interval。 
    wifi_config_t wifi_cfg;
esp_wifi_get_config(WIFI_IF_AP, &wifi_cfg);
wifi_cfg.ap.beacon_interval = 200;
esp_wifi_set_config(WIFI_IF_AP, &wifi_cfg);

esp_mesh_lite_config_t mesh_lite_config = ESP_MESH_LITE_DEFAULT_INIT();
esp_mesh_lite_init(&mesh_lite_config);

If the devices are arranged too closely together, having more than thirty or forty devices can cause issues such as application layer disconnections. This is mainly because all devices are on the same channel, and channel congestion prevents Wi-Fi data frames from being sent, leading to application layer disconnections.

Here are two suggestions:

  1. Arrange the devices more sparsely to reduce wireless interference between devices.
  2. Appropriately increase the beacon interval. 
    wifi_config_t wifi_cfg;
esp_wifi_get_config(WIFI_IF_AP, &wifi_cfg);
wifi_cfg.ap.beacon_interval = 200;
esp_wifi_set_config(WIFI_IF_AP, &wifi_cfg);

esp_mesh_lite_config_t mesh_lite_config = ESP_MESH_LITE_DEFAULT_INIT();
esp_mesh_lite_init(&mesh_lite_config);

我设置了wifi_cfg.ap.beacon_interval = 200;，然后设备放置间距1m~2m。60个设备依然出现网络问题。

信号强度太弱了，可以用 esp_mesh_lite_set_rssi_threshold 设置下信号强度，比如 -75，这样连接时，会跳过 低于 -75 的 AP

LYL14 commented

这个函数的传参您理解吗，我有些没看懂 esp_mesh_lite_rssi_threshold_list_t 这个变量是设置在不同层的RSSI值吗。

xcguang commented 
static const esp_mesh_lite_rssi_threshold_list_t rssi_level[] = {
      {0,  -35, 20},
      {-35,  -55, 15},
      {-55,  -75, 10}
  };
 
esp_err_t result = esp_mesh_lite_set_rssi_threshold(rssi_level, sizeof(rssi_level) / sizeof(esp_mesh_lite_rssi_threshold_list_t), -75);
if (result == ESP_OK) {
     // RSSI threshold list set successfully
} else {
     // Failed to set the RSSI threshold list
}

这样试试呢
