Current consumption of 320uA after ble advertising stopped.

[Surya]

My custom board with NRF52810 doesn't have an external LF clock, so I am using Synthesised Option.

as per my knowledge clock source will take 320 uA (~200 uA for HF clock and remaining for Lf clock circuitry)

but after stopping BLE advertising it still taking 320 uA.

I Tried running a simple example from sdk17(ble_app_pwr_profiling) in NRF52832 DK board and measured the current,

for Synthesised LF clock Source it is drawing after stopping advertising but for external LF clock (as Board comes with one) 

it is not drawing any current. can anybody point out problem here?

You should get around 2uA in System ON idle with the RC running and Softdevice enabled, so I think it must be something else.

I am unable to find out which causing power consumption. can you point out possible sources of current 125 uA to 130 uA

[Vidar Berg]

130 uA is a bit unusual. I can't think of anything obvious that would lead to this base current. Are you using the same code as you described here: https://devzone.nordicsemi.com/f/nordic-q-a/65061/power-consumption-of-180-ua-during-low-power-system-on

i am using pwr_mgmt_run()
