Zigbee no communication between Coordinator and End Device

[sjf]

Hi,

We have been working with a Zigbee coordinator, router and an end device based on nRF52840 with nRF5_SDK_for_Thread_and_Zigbee_v4.0.0_dc7186b, Softdevice and FreeRTOS. We are currently having issues on this case after some time the network is established:

The router and end device are configured to send periodically reports to the coordinator. The coordinator receives them correctly

The end device's parent is the router (nwkAddr 0xa3ce). End device's address is 0xa6f5

The coordinator is requested to send a Write Attribute command to the end device. Instead of sending that command it sends a Network Address Request with the End Device MAC Address (f4ce360eda268ac1). The router replies with the End Device nwkAddr

The coordinator then sends a Route Request with the End Device nwkAddr but is never replied

The WriteAttr Request is never sent and the coordinator logs periodically ZB_NLME_STATUS_INDICATION Status 0

On the End Device, no ZB_NLME_STATUS_INDICATION is logged.

Why this situation occurs and why it could not be properly handled by the stack?

Please find Wireshark log attached

Regards

Santiago

 Hi and sorry for the late reply. How are you requesting the coordinator to send the Write attribute command?

Hi, thanks for your response. We are sending the 

...
zb_addr_u remote_node;

// get buffer

bufid = zb_buf_get_out();
...

p_row->attr.direction = ZB_ZCL_FRAME_DIRECTION_TO_SRV;  

// set nwk address 
remote_node.addr_short = nwk_addr; 
ZB_ZCL_GENERAL_INIT_WRITE_ATTR_REQ_A(bufid, p_cmd_buf, p_row->attr.direction, ZB_ZCL_ENABLE_DEFAULT_RESPONSE); 
for(c = 0; c < p_row->attr.total_attrs; c++) 
{ 
 ZB_ZCL_GENERAL_ADD_VALUE_WRITE_ATTR_REQ(p_cmd_buf, p_row->attr.attr_ids[c], p_row->attr.attr_types[c], p_row->attr.attr_values[c]);
} 

ZB_ZCL_GENERAL_SEND_WRITE_ATTR_REQ(bufid, p_cmd_buf, remote_node, ADDR_SHORT, p_row->remote_ep, local_ep, p_row->profile_id, p_row->cluster_id, zbm_frame_acked_cb);
