Max Zigbee endpoints

[sjf]

Hi, 

We are currently developing a Zigbee network based on nRF52840.

One of our devices was specially designed to contain 8 endpoints. But when an active ep request is sent it just retrieves 6 endpoints.

How can this setting be adjusted within the Zboss stack to increase the number to 8 endpoints?

We tried to undef and redefine ZB_MAX_EP_NUMBER at zb_config.h without luck.

Regards,

Hello,

I don't know whether that is the way to change the number of EPs supported. In what file did you change it?

From zb_vendor.h in SDK4.1.0:

/* Compile-time memory configuration: hard-coded parameters.

   DO NOT CHANGE IT WHEN COMPILING APPLICATIONS USING PRE-COMPILED ZBOSS LIBRARIES!
 */
#define ZB_PANID_TABLE_SIZE 28
#define ZB_DEV_MANUFACTORER_TABLE_SIZE 32
#define ZB_BUF_Q_SIZE 8
#define ZDO_TRAN_TABLE_SIZE 16
#define ZB_APS_ENDPOINTS_IN_GROUP_TABLE 8
#define ZB_NWK_BTR_TABLE_SIZE 16
#define ZB_NWK_BRR_TABLE_SIZE 16
#define ZB_MAX_EP_NUMBER 6
...

Let me check with our Zigbee team whether they have any ways to work around this limit. Either way, if this file is included in the project, then the definition of ZB_MAX_EP_NUMBER om zn_config.h will not be used, since it is already defined, and because of the #ifndef guard:

#ifndef ZB_MAX_EP_NUMBER                                // Anything in between this line...
/* max supported EP number, increase if needed */
/** Maximum number of supported enpoints per device */
#define ZB_MAX_EP_NUMBER 5
#endif                                                  // And this line is not included if ZB_MAZ_EP_NUMBER is already defined elsewhere.

Hi Edvin,

Thanks for your reply.

We use #undef ZB_MAX_EP_NUMBER and then #define ZB_MAX_EP_NUMBER 8 to redefine this value without success.

Hi Edvin, 

Do you have any update on this? The reported active ep list does not change when updating ZB_MAX_EP_NUMBER at zb_config.h

We erased prev config by setting ERASE_PERSISTENT_CONFIG to true and then back to false but reported eps is always fixed at 6.

Hello,

No updates yet. I have asked our Zigbee team whether it is possible to increase this number. 

As mentioned, the definition of ZB_MAX_EP_NUMBER will not take effect when zb_vendor.h is included in your project, and based on zb_vendor.h, the zboss stack doesn't support more than 6 endpoints. I'll let you know when I hear from our Zigbee Team.

BR,

Hi Edvin,

Thanks for your response. We will wait for updates.
