POFWARN

[Muhammad]

Hi,

I'm working on the nrf52832 development board and SDK 16.0. I want to use the Power supply supervisory functionality to detect any type of power failure.

I'm using ble Blinky example with softdevice s132 to test this.

I just want to know, How can I register my event with the soft device.

I have seen many examples regarding the POFWARN at this forum but unable to implement it in code. 

    err_code = sd_power_pof_enable(POWER_POFCON_POF_Enabled);
    APP_ERROR_CHECK(err_code);

    err_code = sd_power_pof_threshold_set(POWER_POFCON_THRESHOLD_V28);
    APP_ERROR_CHECK(err_code);

but I don't know where how to get the warning NRF_EVT_POWER_FAILURE_WARNING  by incorporating with the softdevice. If there is any example stating the procedure or any help will be grateful.

Thanks

'm_advertising_soc_obs' undeclared (first use in this function); did you mean 'Advertising_Start'?

This is the error that compiler shows and the screenshot of the code attached. also, there is a warning.

Hi Muhannad, 

Could you try to use the Template Application?

I saw the same issue in the blanky example instead of the template example.

I have tried this in blinky code it worked there, but it is not working in my custom application.

Hi, 

Please check the NRF_SDH_SOC_ENABLED is set to 1 in the sdk_config.h and Include header files for  nRF5_SDK\components\softdevice\common\nrf_sdh_soc.h

And that these files (under nRF5_SDK\components\softdevice\common\) are included in your project:
