Previously, I am using X-CTU version 5.2.8.6 to configure Zigbee module ‘S2’ as END Device or Router now I am using 6.3.0 version of X-CTU to configure Zigbee module ‘S2C’, but not able to configure as END Device / Router. i.e ‘function set’ is not getting changed to ‘END Device’ / Router.

Simple, enable the sleep mode function (SM).
