Using ESP-IDF
ESP_ERROR_CHECK(esp_event_loop_create_default()); esp_netif_t* wifiStaNetif = esp_netif_create_default_wifi_sta(); const char* hostname = "MyESP32"; ESP_ERROR_CHECK(esp_netif_set_hostname(wifiStaNetif, hostname));
Using Arduino framework
Use
WiFi.config(INADDR_NONE, INADDR_NONE, INADDR_NONE); WiFi.setHostname("My-ESP32-Test");
to set a custom hostname for the ESP32. The Wifi.config(...)
line is required as a workaround for this bug on Github.
