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 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).
