Getting zigbee device RSSI/LQI value of all network device

[Dhaval Dalvadi]

How can we retrieve all network devices RSSI/LQI value?

Is there option to subscribe value for LQI ?
We just want to showcase LQI/RSSI on server so user be aware if device are placed in proper range or not.

void zb_zdo_mgmt_lqi_cb(zb_uint8_t param)
{
    zb_buf_t *buf = ZB_BUF_FROM_REF(param);
    zb_zdo_mgmt_lqi_resp_t *resp = (zb_zdo_mgmt_lqi_resp_t*)ZB_BUF_BEGIN(buf);
    zb_zdo_neighbor_table_record_t *record = (zb_zdo_neighbor_table_record_t*)(resp + 1);
    for (zb_uint8_t i = 0; i < resp->neighbor_table_entries; i++)
    {
        if (record->device_type == ZB_ZDO_DEVICE_TYPE_ROUTER)
        {
            ZB_LETOH64(record->ext_addr);
            TRACE_MSG(TRACE_APS3, "Router found: " TRACE_FORMAT_64,
                      (FMT__A, TRACE_ARG_64(record->ext_addr)));
        }
        record++;
    }
    zb_free_buf(buf);
}
void get_router_list(void)
{
    zb_zdo_mgmt_lqi_param_t *req;
    zb_buf_t *buf = zb_buf_get_out();
    req = ZB_BUF_GET_PARAM(buf, zb_zdo_mgmt_lqi_param_t);
    req->start_index = 0;
    req->dst_addr = 0x0000;  // Coordinator address
    zb_zdo_mgmt_lqi_req(ZB_REF_FROM_BUF(buf), zb_zdo_mgmt_lqi_cb);
}

Its not able to know if its router or end device both gives similar value most of the cases
