Ethernet ESP32 : Comment obtenir la vitesse actuelle du lien

Voici comment vous pouvez obtenir la vitesse actuelle du lien d’une connexion Ethernet sur l’ESP32 en utilisant le framework ESP-IDF.

esp_eth_get_speed.cpp

#include <esp_eth.h>

// Obtenir la vitesse du lien
eth_speed_t link_speed;
if (esp_eth_ioctl(eth_handle, ETH_CMD_G_SPEED, &link_speed) == ESP_OK) {
    const char* speed_str = (link_speed == ETH_SPEED_10M) ? "10 Mbps" :
                          (link_speed == ETH_SPEED_100M) ? "100 Mbps" : "1000 Mbps";
    ESP_LOGI(TAG, "Ethernet Speed: %s", speed_str);
}

#include <esp_eth.h>

// Obtenir la vitesse du lien
eth_speed_t link_speed;
if (esp_eth_ioctl(eth_handle, ETH_CMD_G_SPEED, &link_speed) == ESP_OK) {
    const char* speed_str = (link_speed == ETH_SPEED_10M) ? "10 Mbps" :
                          (link_speed == ETH_SPEED_100M) ? "100 Mbps" : "1000 Mbps";
    ESP_LOGI(TAG, "Ethernet Speed: %s", speed_str);
}
