How to Retrieve Supported Cluster List from a Zigbee End Device?

Question

Hi, 
 How can I retrieve the complete list of supported input and output clusters for all endpoints on a Zigbee end device? I'm currently able to access the On/Off cluster for a plug, but I need to get the full list of supported clusters for the device. 
 Thanks in advance for your help!

static void send_simple_desc_req(zb_bufid_t buf)
{
  if (!buf)
  {
    zb_buf_get_out_delayed(send_simple_desc_req);
  }
  else
  {
    zb_zdo_simple_desc_req_t *req;
    req = zb_buf_initial_alloc(buf, sizeof(zb_zdo_simple_desc_req_t));
    req->nwk_addr = 0; /* send to coordinator */
    req->endpoint = 5;
    zb_zdo_simple_desc_req(buf, simple_desc_callback);
  }
}


static void simple_desc_callback(zb_bufid_t buf)
{
  zb_uint8_t *zdp_cmd = zb_buf_begin(buf);
  zb_zdo_simple_desc_resp_t *resp = (zb_zdo_simple_desc_resp_t*)(zdp_cmd);
  zb_uint_t i;
 
  TRACE_MSG(TRACE_APS1, "simple_desc_resp: status %hd, addr 0x%x",
            (FMT__H, resp->hdr.status, resp->hdr.nwk_addr));
  if (resp->hdr.status != ZB_ZDP_STATUS_SUCCESS || resp->hdr.nwk_addr != 0x0)
  {
    TRACE_MSG(TRACE_APS1, "Error incorrect status/addr", (FMT__0));
  }
 
  TRACE_MSG(TRACE_APS1, "simple_desc_resp: ep %hd, app prof %d, dev id %d, dev ver %hd, input count 0x%hx, output count 0x%hx",
            (FMT__H_D_D_H_H_H, resp->simple_desc.endpoint, resp->simple_desc.app_profile_id,
             resp->simple_desc.app_device_id, resp->simple_desc.app_device_version,
             resp->simple_desc.app_input_cluster_count, resp->simple_desc.app_output_cluster_count));
 
  TRACE_MSG(TRACE_APS1, "simple_desc_resp: clusters:", (FMT__0));
  for(i = 0; i < resp->simple_desc.app_input_cluster_count + resp->simple_desc.app_output_cluster_count; i++)
  {
    TRACE_MSG(TRACE_APS1, " 0x%hx", (FMT__H, *(resp->simple_desc.app_cluster_list + i)));
  }

I used this example but not worked nrf restarted and getting below error

[00:00:05.834,136] <inf> app: 0
[00:00:05.878,356] <err> zboss_osif: ZBOSS fatal error occurred

Hi, 
 To get all endpoints you can send an Active Endpoint request using zb_zdo_active_ep_req() . 
 Best regards, Marte
