The whole point of standards like BLE is that they are Standard - so things don't depend on what particular chip(s) you're using.

Your peripheral neither knows nor cares what the Central is- it is just a Central.

[quote userid="80825" url="~/f/nordic-q-a/49019/rssi-values/195032"]my code is for peripheral[/quote]

So it can't possibly work.

The code which Sunil vignesh suggested is for a Peripheral

No sir my code is for peripheral , What to change in the ble_peripheral_app_blinky code to get the rssi value using mobile and nrf52840 dk

An Advertising Report is only ever going to happen in a Central.

Your code is for a Central - isn't it?

The code which Sunil vignesh suggested is for a Peripheral ...

the code Sunil vignesh suggested uses 2 nrf52800 and i m using only 1

1 nrf52800 and my mobile which is acting as advertiser

[quote userid="80825" url="~/f/nordic-q-a/49019/rssi-values/195006"]is this correct[/quote]

In isolation, it's OK - but the way you've included it with the rest of your code is wrong

That's really unhelpful!

It means that answers which referred to the code as originally posted no longer make sense!

Please don't do that.

But your updeated code has no 'break' at the ends of the 'Connected' and 'Advertising Report' events

    switch (p_ble_evt->header.evt_id)
    {
        case BLE_GAP_EVT_CONNECTED:
            NRF_LOG_INFO("Connected");
            bsp_board_led_on(CONNECTED_LED);
            bsp_board_led_off(ADVERTISING_LED);
            m_conn_handle = p_ble_evt->evt.gap_evt.conn_handle;
            err_code = nrf_ble_qwr_conn_handle_assign(&m_qwr, m_conn_handle);
            APP_ERROR_CHECK(err_code);
            err_code = app_button_enable();
            APP_ERROR_CHECK(err_code);
            
            /* *************** NEED A 'break' HERE ! *************** */
        
         case BLE_GAP_EVT_ADV_REPORT:
            
              NRF_LOG_INFO("RSSI: %d", p_ble_evt->evt.gap_evt.params.adv_report.rssi);
              NRF_LOG_INFO("POWER: %d", p_ble_evt->evt.gap_evt.params.adv_report.tx_power);
            
            /* *************** NEED A 'break' HERE ! *************** */

Have you looked at the code which Sunil vignesh suggested?

 case BLE_GAP_EVT_ADV_REPORT:
            
              NRF_LOG_INFO("RSSI: %d", p_ble_evt->evt.gap_evt.params.adv_report.rssi);
              NRF_LOG_INFO("POWER: %d", p_ble_evt->evt.gap_evt.params.adv_report.tx_power);

is this correct?

You could have just updated your original post - istead of starting a whole new thread!

https://devzone.nordicsemi.com/f/nordic-q-a/49017/rssi-value

You are doing your processing outside the 'switch', but the fields you are using are only valid when the even is an Advertising Report!

Therefore you need to put your code in a 'case' in your 'switch' for the advertising report.
