nRF52810 restart advertising causes high current

[ToddKuo]

Hi,
I restart advertising with ble_advertising_start and sd_ble_gap_adv_stop because I need to change the advertising interval in different situations. I am observing high current (about 1.6mA) when restarting the advertising, is this normal?
Why restarting has high current? What hardware components is this related to? Can this current be lower?

Thanks.

Hello,

Which sample/ example you are working on? Is this nRFSDK or NCS? If you want can send your project so that I can try to check by PPK from my side.

Thanks.

Hello,

I found the root cause.
I used a 100ms delay between sd_ble_gap_adv_stop and ble_advertising_start.
The system cannot go to sleep, so there will be additional current consumption.

Thank you.
