Hi Vishal,
The zps_gen.c/h These are generated files. Do not edit.
Be sure that you are modifying the correct zpscfg file. The jn-an-1216 provides 4 different files and depending on the example that you have active it will be selected. You can modify this in the makefile.
I compile the Zigbee Node Control Bridge Coordinator for the JN5199
It is taking this file ZigbeeNodeControlBridgeCoordinator_GP_Proxy.zpscfg
I am not sure if you want to work with the Preconfigured key, but it is no longer supported feature.User can use AddReplaceLinkKey and SetInitialSecurityState instead.
Regards,
Mario
