BLE ad channel

Question

I would like to know how to see on which channel our BLE device advertises its data. Can we customize (change) ourselves or select it randomly?

I know that there are three channels allocated for advertising BLE data.

Answer 1

You can set chan_mapusing the structure le_set_advertising_parametersfor advertising on a specific channel

Answer 2

If you want to know about the channel through which advertising data is transmitted, you can create a packet sniffer for yourself ...
