During initialization, MAC addresses for each network interface are generated or derived from a single base MAC address. If the number of universal MAC addresses is two, all interfaces (WiFi station, WiFi softap) receive a universally administered MAC address. They are generated sequentially by adding 0, and 1 (respectively) to the final octet of the base MAC address. If the number of universal MAC addresses is one, only WiFi station receives a universally administered MAC address. The WiFi softap receives local MAC addresses. It's derived from the universal WiFi station MAC addresses. When using the default (Espressif-assigned) base MAC address, either setting can be used. When using a custom universal MAC address range, the correct setting will depend on the allocation of MAC addresses in this range (either 1 or 2 per device). config ESP32S2_UNIVERSAL_MAC_ADDRESSES_ONE bool "Two" select ESP_MAC_ADDR_UNIVERSE_WIFI_STA config ESP32S2_UNIVERSAL_MAC_ADDRESSES_TWO bool "Two" select ESP_MAC_ADDR_UNIVERSE_WIFI_STA select ESP_MAC_ADDR_UNIVERSE_WIFI_AP endchoice config ESP_MAC_ADDR_UNIVERSE_WIFI_AP bool config ESP_MAC_ADDR_UNIVERSE_WIFI_STA bool config ESP32S2_UNIVERSAL_MAC_ADDRESSES int default 1 if ESP32S2_UNIVERSAL_MAC_ADDRESSES_ONE default 2 if ESP32S2_UNIVERSAL_MAC_ADDRESSES_TWO endif # SOC_ESP32S2
