Hi,
Hardware：nRF52840 module, Power Profile Kit.
SDK：nRF5_SDK_15.2.0_9412b96.
Using Power Profile Kit to measure the low power consumption current of an nRF52840 product module, the abnormal current consumption is found as follows.
From the detection data, when the chip is low power consumption, the average current is 60-80μA, but there will be periodic current consumption. I am confused where this consumption may come from?
FreeRTOS is used in engineering code and two tasks are created: SDK default "software device_task" , user task "test_task". The pseudocode for the test_task task task is as follows.
void test_task(void * pvParameter)
{
Low_Power_Mode_Close();
...... // do something
Low_Power_Mode_Open();
vTaskDelay(5000);
}
