Yes, the central is receiving the advertising packet you are sending with the mobile app. RSSI and PEER_ADDR is included in the advertising packet.

But i am getting peripheral mac id (PEER_ADDR) and RSSI values

If you see the printf "Advertiesing....." then you are receiving the advertising packets. But, the central will only connect to peripherals that have the Nordic UART service.

yes. i am using nrf connect mobile app based advertiser.

Are you getting the printf "Advertiesing....."? What peripheral are you using?

Then how to find peripherals? ble_event.txt

The central is not receiving any advertising packets?

Hi Sigurd,

Thanks for reply. As per your advice disable the hardware flow control uart working fine but not get advertising packet. My application is display the MAC ID and RSSI value in advertising event function.

Hi,

First you will need to disable the flow-control. In the function uart_init() make sure you have APP_UART_FLOW_CONTROL_DISABLED. The function will then look like this:

static void uart_init(void)
{
    uint32_t err_code;

    const app_uart_comm_params_t comm_params =
      {
        .rx_pin_no    = RX_PIN_NUMBER,
        .tx_pin_no    = TX_PIN_NUMBER,
        .rts_pin_no   = RTS_PIN_NUMBER,
        .cts_pin_no   = CTS_PIN_NUMBER,
        .flow_control = APP_UART_FLOW_CONTROL_DISABLED,
        .use_parity   = false,
        .baud_rate    = UART_BAUDRATE_BAUDRATE_Baud115200
      };

    APP_UART_FIFO_INIT(&comm_params,
                        UART_RX_BUF_SIZE,
                        UART_TX_BUF_SIZE,
                        uart_event_handle,
                        APP_IRQ_PRIORITY_LOW,
                        err_code);

    APP_ERROR_CHECK(err_code);
}

You must also turn off the flow-control in your terminal, and choose the correct baudrate.

In Termite the settings would look something like this:
