      Star network, 1 Coordinator / 6 End Devices (no router).

Remarks

      Is there any way to modify this value? Such as, modifying macro definition, modifying structural variable, calling an interface.

Hi, I hope you're doing well!

 

To allow more child devices (either router or end devices), you can change the ZPS_CHILD_TABLE_SIZE macro from 6 to the number of devices you want to allow as children to the coordinator. Still, you'll have to consider if there's still space in the other types of tables. You can read more about these macros in the ZigBee 3.0 Stack User Guide, which is included with the KW41Z's SDK, in the following path:

 

<…\SDK_SDK_2.2.1_FRDM-KW41Z\docs\wireless\Zigbee\ZigBee 3.0 Stack User Guide.pdf>

 

Best regards,

Sebastian

I had already seen it. The ZPS_CHILD_TABLE_SIZE is not in <ZigBee 3.0 Stack User Guide.pdf>. So I could not find it before.
