Increase Zigbee MAX ENDPOINTS for nrf52840

[Karthik Bhandge]

I am posting this query again as the previous query is closed and unanswered  https://devzone.nordicsemi.com/f/nordic-q-a/88349/increase-zigbee-max-endpoints-for-nrf52840  

Hi, I am developing a zigbee device  on Nrf connect sdk 1.9.1 which has 9 endpoints, i am not able to create more than 8 endpoints perfectly.

i tried to change ZB_MAX_EP_NUMBER in "v1.9.1\nrfxlib\zboss\production\include\osif\zb_vendor.h" file and  https://github.com/nrfconnect/sdk-nrfxlib/blob/6195aa85b705a5786cb0bc20ec9a4912355f0afc/zboss/development/include/osif/libzboss_config.h#L508 but the issue was not solved.

when i changed #define CONFIG_ZB_MAX_EP_NUMBER 8 to #define CONFIG_ZB_MAX_EP_NUMBER 9, my nrf52840 is crashing at bootup.

Hi Karthik,

Good to hear your feedback.

There is one related discussion one year ago: Max Zigbee endpoints - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com), I am not sure if you still need to join ZOI or contact our RSM for this inquiry. I will give you a reply later.

Best regards,

Charlie

Hi Karthik,

ZB_MAX_EP_NUMBER  is fixed at compiling time in the ZBOSS stack. The NCS Zigbee solution uses a prebuilt and certificated ZBOSS stack. All Kconfig starting from CONFIG_ZB_ are not meant to be changed in the NCS workflow(only in ZOI workflow). You need to join ZOI in order to change and recompile the ZBOSS stack for your product.

Best regards,

Charlie

Hi Charlie, 

Thank you for your quick response.

As lots of companies are facing this issue, I was wondering if you (i.e Nordic) can increase the max endpoints from 8 to 12, or a simple option to increase the endpoints till 12 will be very helpful.
