S120 scanner handling of ADV_IND with no scan response

[Matt Barr]

Hello All,

For the S120 softdevice active scanner, it appears that when ADV_IND is received and a scan request/response exchange occurs there will be two BLE_GAP_EVT_ADV_REPORT events sent to the application, one for the ADV_IND packet and one for the scan response. The ble_gap_evt_adv_report_t::scan_rsp field specifies which is which.

If ADV_IND is received but for some reason the scan response is not, will the BLE_GAP_EVT_ADV_REPORT event associated with the ADV_IND packet be sent to the application?

Thanks and Best Regards, Matt

You are correct. There will be one BLE_GAP_EVT_ADV_REPORT for the ADV_IND and one for SCAN_RSP.

If only ADV_IND is received, and not SCAN_RSP, the application will only get one BLE_GAP_EVT_ADV_REPORT.
