Hi,

You could turn off the features in the sdk_config.h if they are not used in the project. 

 

Q2：Is there any risk for setting heap and stack to zero in makefile file to reduce the ram consumption in n ble_app_buttonless_dfu example project?

 If you don't use any dynamic memory you can safely set the heap size to 0. Neither the SoftDevice nor any of the SDK examples/libraries use the heap.
