sd_power_system_off(); How can I use this function to shut down the device, and then how can I boot the device?

[liuyanfeng]

Now I use nrf52810 to develop a device, and now I want to use SD_ power_ system_ Off (); turn off the device, and now turn on the device again. What can I do to achieve this function?

Now I use P11 of nrf52810 as the interrupt pin of gpiote. That is to say, pressing P11 will turn off the device. I want to use P11 to turn on the device.

Help me, thank you very much!

Hi yanfeng,

The pwr_mgmt_example is exactly what you want.

According to nRF52810 PS:

When in System OFF mode, the device can be woken up through one of the following: 1. The DETECT signal, optionally generated by the GPIO peripheral 2. A reset 

So you only need to set the GPIO to sense specific kind of signal like the code from pwr_mgmt_example:

nrf_gpio_cfg_sense_set(bsp_board_button_idx_to_pin(button_idx), sense);

 Best regards,

Charlie

I mean, pin P of nrf52810 makes an input. If I press and hold for a few seconds, nrf52810 will enter shutdown mode, that is, calling SD_ power_ system_ When the pin P of nrf52810 is touched again, nrf52810 can work again. That's it. Do you understand?

I've seen the routine you said. It hasn't been tested yet, but thank you
