Advertising Config (Peripheral) for Active Scanning (Central)

[KRAm]

Hello, Dear Support!

I explore examples in SDK 15.3.0 : ble_app_hrs and ble_app_rscs. The peripheral device in ble_app_rscs is configured to wait active request from central device before sending advertising packet, and the peripheral in ble_app_hrs starts advertising immediately after switching on. But advertising_init() in main.c and Advertising module settings in sdk_config.h for both examples looks the same. Could you point me where advertising settings of peripheral device configure to work with active or passive scan central device?

Thank You.

Hello,

ble_app_rscs does not wait for a scan before advertising.

The difference in advertising between these two examples is that ble_app_rscs uses extended advertising.

init.config.ble_adv_extended_enabled = true;

Passive/active scanning is not something that is set on the peripheral side. It is set on the central side. Active scanning means it will send a scan request to the peripheral, and the peripheral can answer with scan response data.
