Configurations of Zigbee

Hi,

I want to change the panid , Short id, via proj.conf

When you say short id, do you mean the short address/network address?

how to set the panid from proj.conf

You can set the PAN ID with the function ZB_PIBCACHE_PAN_ID(); from the NWK functions API. 

This function must be called before the stack starts, i.e before zigbee_enabled() is called in main. If you desire to set this in proj.conf you must create a Kconfig file (or use the existing one if there is one) and add the Kconfig option

source "Kconfig.zephyr"

config ZIGBEE_PAN_ID
    hex "Zigbee PAN ID"

Then define CONFIG_ZIGBEE_PAN_ID=0xyour-pan-id (i.e the ID you want in hexavalue) and set the PAN ID as ZB_PIBCACHE_PAN_ID() = CONFIG_ZIGBEE_PAN_ID; in your application

Let me know if this helps,

Kind regards,
Andreas
