I see now that it's still scannable, in that case you would not see any noticeable difference in power consumption. After advertising, in both connectable and scannable use-cases, the radio RX window need to be opened to listen for a connection request, or scan request from a BLE central.

I have tried to set the broadcast to p_advertising->adv_params.properties.type = BLE_GAP_ADV_TYPE_NONCONNECTABLE_SCANNABLE_UNDIRECTED,But there is no change in power consumption

Hi,

I use the nRF52832 chip, the broadcast interval is one second,set to unconnectable mode, 0dBm power,and the test power consumption is 17.68uA.The following is a test screenshot

Hi,

You should have seen at least a small decrease. How much power consumption did you measure? What advertising interval are you using ?
