Ok. What are you missing to do that?

Thank you, Edvin!

I would like to print the rssi value as a level 0 command on the cli for the devices that come in when the scan is on (without having to connect to the device). I am using SDK version 15.3.0.

Hello,

What is it that you want to print the RSSI value on? The advertisement packets that you scan?

If that is the case, What SDK version are you using? The reason I ask is that the advertisement reports are located different places in different SDKs. Either way, look for an event called BLE_GAP_EVT_ADV_REPORT. This event typically has an input parameter, p_ble_evt.

You can find the RSSI of an advertisement packet the following way:

case BLE_GAP_EVT_ADV_REPORT:
    int8_t rssi = p_ble_evt->evt.gap_evt.params.adv_report.rssi;
    
    
    NRF_LOG_INFO("received an advertisement with RSSI %d", rssi);
    NRF_LOG_INFO("from address: %02x, %02x, %02x, %02x, %02x, %02x", p_ble_evt->evt.gap_evt.params.adv_report.peer_addr.addr[0],
                                                                     p_ble_evt->evt.gap_evt.params.adv_report.peer_addr.addr[1],
                                                                     p_ble_evt->evt.gap_evt.params.adv_report.peer_addr.addr[2],
                                                                     p_ble_evt->evt.gap_evt.params.adv_report.peer_addr.addr[3],
                                                                     p_ble_evt->evt.gap_evt.params.adv_report.peer_addr.addr[4],
                                                                     p_ble_evt->evt.gap_evt.params.adv_report.peer_addr.addr[5]);
    break;

You can use CLI instead of NRF_LOG_INFO(), but it was easier to just show using the logger module.

Best regards,

Edvin
