Expand description
@brief request controller to wakeup from sleeping state during sleep mode
Note that this function shall not be invoked before esp_bt_controller_enable() Note that this function is supposed to be used ORIG mode of modem sleep Note that after this request, bluetooth controller may again enter sleep as long as the modem sleep is enabled
Profiling shows that it takes several milliseconds to wakeup from modem sleep after this request. Generally it takes longer if 32kHz XTAL is used than the main XTAL, due to the lower frequency of the former as the bluetooth low power clock source.
