Update: This could be a ZCL layer bug,

Assuming that you use Production version of ZBOSS libraries, this is what should fix the issue:

Change zb_zcl_window_covering_invoke_user_app() function in nrxlib/zboss/production/src/zcl/zcl_window_covering.c:172 :

From:

static zb_ret_t zb_zcl_window_covering_invoke_user_app(zb_uint8_t param,
                                                       const zb_zcl_parsed_hdr_t *cmd_info,
                                                       zb_zcl_device_callback_id_t user_cb_id,
                                                       void *payload)
      {
  zb_ret_t ret = RET_OK;
  TRACE_MSG(TRACE_ZCL1, "> zb_zcl_window_covering_invoke_user_app cb_id %d", (FMT__D, user_cb_id));
  ZB_ZCL_DEVICE_CMD_PARAM_INIT_WITH(param, user_cb_id, RET_OK, cmd_info, payload, NULL);
  if (ZCL_CTX().device_cb != NULL)
  {
    (ZCL_CTX().device_cb)(param);
      }

To:

static zb_ret_t zb_zcl_window_covering_invoke_user_app(zb_uint8_t param,
                                                       const zb_zcl_parsed_hdr_t *cmd_info,
                                                       zb_zcl_device_callback_id_t user_cb_id,
                                                       void *payload)
      {
  zb_ret_t ret = RET_OK;
  TRACE_MSG(TRACE_ZCL1, "> zb_zcl_window_covering_invoke_user_app cb_id %d", (FMT__D, user_cb_id));
  ZB_ZCL_DEVICE_CMD_PARAM_INIT_WITH(param, user_cb_id, RET_OK, cmd_info, payload, NULL);
  /* Set endpoint meant to receive this command. */
  ZB_ZCL_DEVICE_CMD_PARAM(param)->endpoint = ZB_ZCL_PARSED_HDR_SHORT_DATA(cmd_info).dst_endpoint;
  if (ZCL_CTX().device_cb != NULL)
  {
    (ZCL_CTX().device_cb)(param);
      }

Hi,

Nothing apparent in you code you have shared that would indicate what the issue could be.

So issue might be with the command that is being send or it could be how you declarer endpoints. So here here a couple of things that you can do to further debug.

To check if the issue lies within the command used:
- Do a sniffer log of the commands, can use nRF Sniffer for 802.15.4, then shar the log with us as a pcap file. Make sure that the sniffer is started before the coordinator starts the network so that the sniffer has the network key.

Ckeck the endpoint:
- Using Zigbee shell you can see if both endpoints are on the device. So add a extra device\DK to the network by programming the Zigbee: Shell and set it up so that it joins the same network as the other devices. Then you can use the zdo active_ep command to se what endpoints are on the device you have.

- Share the code where you declarer the endpoints.

Regards,
Jonathan
