I guess you want to add:

p_bas->conn_handle = p_ble_evt->evt.gap_evt.conn_handle;

As far as I see, the bsp_indication_set() does not do much more than setting the LEDs in the example.

I am upload ble_app_hrs code in my board it work perfectly.and as you says add in callback function but in callback function is as like shown below same as ble_app_hrs example,

static void on_ble_evt(ble_evt_t * p_ble_evt)
{
uint32_t err_code;

switch (p_ble_evt->header.evt_id)
{
case BLE_GAP_EVT_CONNECTED:
err_code = bsp_indication_set(BSP_INDICATE_CONNECTED);
APP_ERROR_CHECK(err_code);
m_conn_handle = p_ble_evt->evt.gap_evt.conn_handle;

break;

.
.
}
}

If I understand you correctly, I'm guessing that you assume that the p_bas->conn_handle is set automatically? That is not the case. You need to set it at the BLE_GAP_EVT_CONNECTED event handled in the BLE event callback function.
