Also i have tried to make the following chnages in becon to it adverise and then conncet
i have added the following in the code.

static void conn_params_error_handler(uint32_t nrf_error)
{
APP_ERROR_HANDLER(nrf_error);
}static void conn_params_error_handler(uint32_t nrf_error)
{
APP_ERROR_HANDLER(nrf_error);
}

static void gap_params_init(void)
{
uint32_t err_code;
ble_gap_conn_sec_mode_t sec_mode;
ble_gap_conn_params_t gap_conn_params;
int8_t tx_power = 4;

BLE_GAP_CONN_SEC_MODE_SET_OPEN(&sec_mode);

err_code = sd_ble_gap_device_name_set(&sec_mode, (const uint8_t *)DEVICE_NAME,strlen(DEVICE_NAME));
APP_ERROR_CHECK(err_code);

//The +3dBm setting is only available on nRF52 series ICs.
//Radio transmit power in dBm (accepted values are -40, -30, -20, -16, -12, -8, -4, 0, 3, and 4 dBm).
err_code = sd_ble_gap_tx_power_set(tx_power);
APP_ERROR_CHECK(err_code);

memset(&gap_conn_params, 0, sizeof(gap_conn_params));

gap_conn_params.min_conn_interval = MIN_CONNECTION_INTERVAL;
gap_conn_params.max_conn_interval = MAX_CONNECTION_INTERVAL;
gap_conn_params.slave_latency = SLAVE_LATENCY;
gap_conn_params.conn_sup_timeout = SUPERVISION_TIMEOUT;

err_code = sd_ble_gap_ppcp_set(&gap_conn_params);
APP_ERROR_CHECK(err_code);
}

static void conn_params_init(void)
{
uint32_t err_code;
ble_conn_params_init_t cp_init;

memset(&cp_init, 0, sizeof(cp_init));

cp_init.p_conn_params = NULL;
cp_init.first_conn_params_update_delay = FIRST_CONN_PARAMS_UPDATE_DELAY;
cp_init.next_conn_params_update_delay = NEXT_CONN_PARAMS_UPDATE_DELAY;
cp_init.max_conn_params_update_count = MAX_CONN_PARAMS_UPDATE_COUNT;
cp_init.start_on_notify_cccd_handle = BLE_CONN_HANDLE_INVALID; // Start upon connection.
cp_init.disconnect_on_fail = true;
cp_init.evt_handler = NULL; // Ignore events.
cp_init.error_handler = conn_params_error_handler;

err_code = ble_conn_params_init(&cp_init);
APP_ERROR_CHECK(err_code);
}

is this right?

because when i check in the nrf app the device is not advertising

what changes do i need to make for the device to be advertise and then when central detects it how to i connect to it?(at central end direct connection)

or which example do i make the changes

how do i check for fault handler?

Likely an error occurs, and you have an assert? Have you checked the fault handler?

hey kenneth,

The device is not advertising in the relay example . What can be the possible causes?Earlier it was advertising but not it does not .

i have included the path to ble_nus_c.h even in make file and i still get the error

It seems you have not included the include path to the ble_nus_c.h in your project, so the compiler is not able to find it.
