How to read endddvice's attribute value

[18341265598]

hello everyone:

    The SDK I used is jn-sw-4168, and the Application Template I used is ZigBee PRO Application Template for JN516x (jn-an-1184). Now, at the coordinate end, send data to the enddevice end through ZPS_eAplAfUnicastAckDataReq interface,and receive data normally at the enddevice.But while reading enddevice's custom attribute data with eZCL_SendReadAttributesRequest interface did not return the data, and no generation E_ZCL_CBET_READ_INDIVIDUAL_ATTRIBUTE_RESPONSE or E_ZCL_CBET_READ_ATTRIBUTES_RESPONSE events

The function that reads the attribute data is (at coordinate) :

The services on the enddevice side are my own defined and register.

The log information at coordinator is :

the log information at enddevice is : 

Could you please tell me what caused the failure of my above operation?

Where is the relevant demo code?

Attached is my code， thank you!

Hi, 

From your code seems that you added a custom cluster with Id = 0x1234. Is this cluster set accordingly on the remote device (like server or client functionality,  endpoint ...)? Also a sniffer capture will be useful for this scenario.

My recommendation is to check the read attribute command for a common cluster (let say Basic Cluster = 0x0000) and if it is working for this, means that you have a problem in setting the new cluster on the remote device.

Regards,

Ovidiu

This is my read attribute log （at coordinate）：

This is my read attribute log （at router）：

this is my code：

my sdk is JN-SW-4170，my app template is JN-AN-1217-Zigbee-3-0-Base-Device

thanks！！

1. Do I need to perform service discovery operations before I can read and write attributes?

2. Any demo related to reading and writing?
