Hello,

I am not sure I understand you correctly, but if you intend to find the number of peripherals advertising near your device then I suppose you could use the BLE_GAP_EVT_ADV_REPORT  event and count the peer_addresses. Be advised that centrals do not advertise, and peripherals may advertise as anonymous - so you are not guaranteed to find all BLE devices near you.

In the case that I misunderstood you, you might instead be looking for the nRF Sniffer tool to be monitor surrounding BLE traffic.
This is a powerful tool to have available when developing BLE applications.

Please let me know if this does not answer your question.

Best regards,
Karl
