Couldn't connect to Ember ZigBee endpoint

Hi everyone,

I'm currently working on a project involving an Ember ZigBee end device and a Nordic ZigBee coordinator (Nordic nRF52840 donngle). I’ve encountered an issue where the Ember device sends a beacon request, and although the Nordic coordinator responds, the Ember device does not proceed further.

Upon analyzing the traffic between 2 Ember devices, I noticed that the Ember devices use Stack Profile: Network Specific (0x0) in its beacon, while the Nordic coordinator responds using Stack Profile: ZigBee PRO (0x2). It seems like the mismatch in stack profiles might be the cause of the issue.

I need to configure my Nordic ZigBee coordinator to use the Network Specific stack profile (0x0) instead of the ZigBee PRO profile (0x2). 
I am using the last SDK for the zigbee and thread and I use a cli example 

    Here's what I have tried so far:

    1. Configuration File: I looked into the sdk_config.h file for any settings related to stack profiles but couldn't find anything 
    2. ZBOSS Configuration: I tried to change the values inside zb_config.h and rebuild the project but seems no changes took in place 

    Any insights, specific settings, or examples on how to modify the stack profile for the coordinator would be greatly appreciated. Thanks in advance for your help!
