Configuration of GPIO pin to wake-up from Low power mode

[beemavishnu]

Hello,

 

I am using nRF52832, SDK_15.3.0, S132 SoftDevice and Segger for flash the image.

 

I am using ‘ble_app_bliky” for my application development. In this “Button Handle” module is used for configuring buttons.

My query is, whether there are two types of interrupts configurations ? I mean

 

1) Wake-up due to level trigger on GPIO (In this case chip is in Low power mode).

2) GPIO interrupt due to level trigger (In this case chip is active).

 

In ‘ble_app_template’ I am seeing wakeup_button_cfg() in bsp.c which in-turn updating the ‘Sense’ settings. Do I need to port bsp.c code into ‘ble_app_bliky’ code ?

 

Thanks & Regards

Hi Vishnu,

as long as the button is configured with the Sense functionality it will be able to wake up the chip from both System ON: Low Power and System OFF. 

The Button handling library(app_button.c) configures the input pins with the sense functionality set to toogle, i.e. a low to high or a high to low transition will generate an interrupt. 

Best regards
