NRF54L15 BLE power consumption spikes

Hi,

I am testing the BLE beacon sample on the NRF54L15 PDK, and it was successful as I was able to detect the beacon using the NRF Connect scanner. However, when monitoring the power consumption of this sample, I noticed additional power spikes beyond the expected advertising spikes.



They appear to happen at intervals of around 4 seconds. These spikes are seen when config_bt setting is enabled

The advertising intrevel is set to 10seconds.

using sdk version v2.8.0
toolchain version v2.8.0

Could you help me understand why these spikes are occurring and suggest ways to eliminate them?
thanks in advance for your help
