Zigbee : How to receive data from an IAS ZONE sensor with 52840DK board

[AminGat]

Hello,

I Have an IAS ZONE sensor: Door/Window Sensor DWZB1-CE.

Basically, i want to receive events from this sensor which indicate whether the door is closed or open. On my 52840DK board i have flashed network_coordinator sample which I added the following :

#define DOOR_ENDPOINT 2

/* Declare attribute list for Identify cluster (client). */
ZB_ZCL_DECLARE_IDENTIFY_CLIENT_ATTRIB_LIST(
    simple_sensor_identify_client_attr_list);

/* Declare attribute list for Temperature Measurement cluster (client). */
ZB_ZCL_DECLARE_IAS_ZONE_CLIENT_ATTRIB_LIST(
    ias_zone_client_attr_list);

/* Declare cluster list for the door watcher. */
ZB_DECLARE_DOOR_CLUSTER_LIST(
    door_clusters,
    basic_attr_list,
    simple_sensor_identify_client_attr_list,
    identify_attr_list,
    ias_zone_client_attr_list);

/* Declare endpoint for the door watcher. */
ZB_DECLARE_DOOR_EP(
    door_ep,
    DOOR_ENDPOINT,
    door_clusters);

When i start my board and reset my sensor I have the following logs:
I: Device update received (short: 0x3751, long: 3425b4fffebe8e77, status: 1)                                
I: Device update received (short: 0x6002, long: 3425b4fffebe8e77, status: 1)                                        
I: New device commissioned or rejoined (short: 0x6002)                                                              
I: Joining period extended.
I: Device authorization event received (short: 0x6002, long: 3425b4fffebe8e77, authorization type: 1, authorization status: 0)
I: Unimplemented signal (signal: 54, status: 0)
I: Network steering finished
I: Unimplemented signal (signal: 54, status: 0)

So commisionning works fine. However when i try to close, open door sensor, nothing happen. I try to use sniffer, but the result is the same. I tried using zdo match_desc as suggested here but there only the following logs:

uart:~$ zdo match_desc 0xffff 0xffff 0x0104 2 0x0402 0x0403 0
Sending broadcast request.
 I: Unimplemented signal (signal: 50, status: 0)
Done

How should i modify my code in order to have open/close door event ? Is there any tutorial up to date to implement ias zone sensor ?

Hi,

Can you upload a sniffer log of this as a pcap file?
Make sure to start the sniffer before the coordinator starts the network so the sniffer has the network key, or share the network key here so I can decrypt the packets.

Best regards,
Marte

Hello Marte,

You will find in attachment the sniffer log. I started to sniff just before i flash my nrf-dk board with my network coordinator sample, so it should be early enough to gather all information i guess.

Also how do you decrypt packets with network key ? Is there any documentation about it ?

Thank you for your reply.

Hi,

I do not see any packets related to the sensor being sent in the sniffer log. How are you trying to set up so that the coordinator receives the events from the sensor?

uart:~$ zdo match_desc 0xffff 0xffff 0x0104 2 0x0402 0x0403 0

Make sure to use the correct cluster ID for the clusters implemented on your device. The format of the match_desc command is as follows:

zdo match_desc h:dst_addr
               h:req_addr h:prof_id
               d:n_input_clusters [h:input cluster IDs ...]
               d:n_output_clusters [h:output cluster IDs ...]

So in the above you are sending for a match descriptor request for devices with the Temperature Measurement (0x0402) and Pressure Measurement (0x0403) clusters implemented.

If you have the network key you can add it in Wireshark the same way the ZigbeeAlliance09 and Nordic Examples keys are added in Configuring Wireshark for Zigbee.

Thank you for your reply,

You will find the updated pcap file below. I have used the correct command now :

zdo match_desc 0xffff 0xffff 0x0104 1 0x0500 0

Hi Amin,

I see that you are not receiving any responses to the match descriptor request, even though the IAS Zone cluster should be implemented as an input cluster on the IAS Zone sensor, and not output.
Can you try sending a simple descriptor request to the sensor to get a list of all input and output clusters on the device?

zdo simple_desc_req h:dst_addr d:ep

Best regards,
Marte

Hello,

I do have the following logs :

uart:~$ zdo simple_desc_req 0x6fec 2
uart:~$ I: Unimplemented signal (signal: 50, status: 0)
I: Unimplemented signal (signal: 50, status: 0)
I: Unimplemented signal (signal: 50, status: 0)
I: Unimplemented signal (signal: 50, status: 0)
Error: Simple descriptor request failed

Do you also need a pcap file ?
Amin.

Hi Amin,

Yes, please upload the pcap so I can see why the simple descriptor request fails. Thank you.

Best regards,
Marte

Hi Amin,

You are getting 'Not active' status in the simple descriptor response. Are you sending the simple descriptor request to the correct endpoint on the sensor?

Best regards,
Marte

Hello !

Thank you for your reply, indeed  I made a mistake. You will find the correct pcap file this one with a success status for both  zdo match_desc and zdo simple_desc_req.
On the Terminal there were an output of these two commands. For instance:

uart:~$ zdo simple_desc_req 0x72c3 1
src_addr=0x72c3 ep=1 profile_id=0x0104 app_dev_id=0x402 app_dev_ver=0x1 in_clusters=0x0000,0x0001,0x0003,0x0020,0x0402,0x0500,0x0b05 out_clusters=0x0019
Done
