The current peak of 334uA during system on Low power mode

[Surya]

I observed a peak of 334 ua during system-on low-power mode during idle time which is periodic around 4 sec. I am using ble with RC clock option.

1.is it waking for calibration of the clock source?

2.how much current will be drawn for calibration of the clock?

3.how to stop calibration for a time period where ble is not used?

l'm sorry, but what SDK version are you using? I'm not able to find any ble_app_pwr_profiling examples using the ble_stack_stop() function, please be more specific.

Best regards,

Simon

maybe I added that function in the example. I am using SDK 17 (17.0.0_9d13099). anyway, I already mention I am calling "nrf_sdh_disable_request()" in that function.

the function goes as,

void ble_stack_stop(void)
{
uint32_t err_code;

err_code = nrf_sdh_disable_request();
APP_ERROR_CHECK(err_code);

ASSERT(!nrf_sdh_is_enabled());
}
