@ -55,6 +55,10 @@ This change is harmless with standard sketches: Calls to ``WiFi.mode()`` do
enable radio as usual. It also smooths current spikes at boot and decreases
DHCP stress.
Known side-effects:
- ``WiFi.mode()`` must be called before changing mac addresses with ``wifi_set_macaddr({SOFTAP,STATION}_IF, ...)``.
Legacy behavior can be restored by calling ``enableWiFiAtBootTime()`` from
anywhere in the code (it is a weak void function intended to play with the
linker).
