Define "DEBUG" in your preprocessor defines. Then it should print what nrf_ble_scan_filter_set() returns if it doesn't return NRF_SUCCESS. What does it return?

Thankyou even though i am getting fatal error .I checked by breakpoint ,in this line i am getting fatal error ,I think i need to modify or configure

err_code = nrf_ble_scan_filter_set(&m_scan, SCAN_ADDR_FILTER, my_addr);

Look at the description of nrf_ble_scan_filter_set().

I believe you want to call:

err_code = nrf_ble_scan_filter_set(&m_scan, SCAN_ADDR_FILTER, my_addr);
APP_ERROR_CHECK;

Where my_addr is:

m_addr[6] = {0xDF, 0xEF, 0xCD, 0x56, 0x78, 0xFD};

I tried ... i changed .. but i want to add my bluetooth mac address (DF:EF:CE:56:78:FD) This is the address i need to pass where should pass ?

  err_code = nrf_ble_scan_filter_set(&m_scan,  SCAN_ADDR_FILTER, m_target_address);
    APP_ERROR_CHECK(err_code);

    err_code = nrf_ble_scan_filters_enable(&m_scan, NRF_BLE_SCAN_ADDR_FILTER , false);
    APP_ERROR_CHECK(err_code);

Hello,

Look at any of the central examples from the SDK. E.g. The ble_app_uart_c will filter on UUID in the advertising packets.

If you look in sdk_config.h of this example, you can try to set NRF_BLE_SCAN_UUID_CNT to 0, and set NRF_BLE_SCAN_ADDRESS_CNT to 1.

Then, in scan_init() in main.c, you need to change

nrf_ble_scan_filter_set(&m_scan, SCAN_UUID_FILTER, &m_nus_uuid);

to use the address instead of the UUID.

BR,

Edvin
