|
Configure the number of universally administered (by IEEE) MAC addresses. |
|
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 four, all four interfaces (WiFi station, WiFi softap, |
|
Bluetooth and Ethernet) receive a universally administered MAC address. These are generated |
|
sequentially by adding 0, 1, 2 and 3 (respectively) to the final octet of the base MAC address. |
|
If the number of universal MAC addresses is two, only two interfaces (WiFi station and Bluetooth) |
|
receive a universally administered MAC address. These are generated sequentially by adding 0 |
|
and 1 (respectively) to the base MAC address. The remaining two interfaces (WiFi softap and Ethernet) |
|
receive local MAC addresses. These are derived from the universal WiFi station and Bluetooth MAC |
|
addresses, respectively. |
|
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 2 or 4 per device.) |
|
Note that ESP32-C6 has no integrated Ethernet MAC. Although it's possible to use the esp_read_mac() |
|
API to return a MAC for Ethernet, this can only be used with an external MAC peripheral. |
