Hi vivekalways.
First of all, at this moment this application is under development (we are upgrading it to the new SDK version 15.2.0).

As you can see, the app only shows the payload of advertisements and doesn't show another data like RSSI. However, we are going to study this proposal in order to add it in the future.

Anyway, you can try something. If you look at line 85-89 of main.c, you will see the following:

        case BLE_GAP_EVT_ADV_REPORT:
        {
            NRF_LOG_RAW_HEXDUMP_INFO (m_scan.scan_buffer.p_data, m_scan.scan_buffer.len);
            NRF_LOG_RAW_INFO ("----------------------------------\r\n");
        }

The function "ble_evt_handler" is responsible of show the payload of the advertisement. This function receives this parameter:

ble_evt_t const * p_ble_evt

And the structure p_ble_evt has the following field (uint8_t):

p_ble_evt.gap_evt.adv_report.rssi

So probably, you can add this:

        case BLE_GAP_EVT_ADV_REPORT:
        {
            NRF_LOG_RAW_HEXDUMP_INFO (m_scan.scan_buffer.p_data, m_scan.scan_buffer.len);
            NRF_LOG_RAW_INFO ("RSSI: %d\r\n", p_ble_evt.gap_evt.adv_report.rssi);
            NRF_LOG_RAW_INFO ("----------------------------------\r\n");
        }

I can't test this by now, but i hope this helps.

Hi,

I am trying the same as @vivekalways but I don't really know how to do it. Did you finally get the RSSI and UUID?

Thanks!
