NULL_MODE

Hi I use wifi_set_opmode_current(NULL_MODE) to "restart" the network, by calling

wifi_set_opmode_current(NULL_MODE)

wait and then

wifi_set_opmode_current(STATIONAP_MODE)

this works fine in sdk 2.x, but I get fatal error and reboot when doing it in sdk 3.x

any changes here?

Re: system_phy_freq_trace_enable()

Does the option make the chip try to stay on the right frequency or does it just log deviation?
