nRF52 doesn't wake up

[labaip]

Hello , I'm using a couple of nRF52 dev.board (one is Nordic preview dev.kit , the other one is a Rigado BMD-300) , with S212 ant+ softdevice . I'm able to deep-slepp the device but I'm not able to wake-up anyway from deep sleep , pushing button_1 (button_1 is just a sample for testing purpose). I searched for examples and I found everywhere this code but it doesn't work for me ... what's could be wrong ?

nrf_gpio_cfg_sense_input(BUTTON_1, NRF_GPIO_PIN_PULLUP, NRF_GPIO_PIN_SENSE_LOW);
NRF_GPIOTE->INTENSET = GPIOTE_INTENSET_PORT_Msk ;
NVIC_EnableIRQ(GPIOTE_IRQn);
sd_power_system_off();                  // SYSTEM OFF --- WAKE UP pushing FROM BUTTON_1

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

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?

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
