hi attached code for below requirement:
command: scan on - scan devices
command: devices - display filtered devices .
Filters set are for : thermometer, NUS and custom service for nonin sensor.
but i could able to get only thermometer in peripheral device list.
please check and let me know what is wrong with the code.
i am using : SDK 15.02 nRF52832

i have modified ble_app_cli example code to achieve my requirements. attached files main.c, sdk_config.h, ble_cus.c(custom service), ble_cus.h
