EDIT ... After a lot of tests , with Rigado BDM300 eval kit now wake-up works , with my complete code (S212 sdk11 timers saadc ant+ and more) and this simple poweroff-routine :

nrf_gpio_cfg_sense_input(BUTTON_2, NRF_GPIO_PIN_PULLUP, NRF_GPIO_PIN_SENSE_LOW); NRF_POWER->SYSTEMOFF = 1; // SYSTEM OFF mode #1

This is what cares for me ... I have to use Rigado BDM300 module for my jobs , also if the same thing doesn't work with Nordic nRF52 preview kit (maybe first silicon version had some issue ?) and I don't have to use sd_power_system_off() or disable softdevice before power-off . These istructions gave me always a no-wake-up condition. Thanks

Hi. Are you running an unmodified example from the SDK? If so what example and what SDK version number? Is the button you are referring to on the nRF52 preview kit or on one of the other modules? Do you have link to the module?

Anybody tried S212 v.9.0.1 alpha , deep sleep and wake up functionality ? Some sample code ? Maurizio
