Hello suga_4501896 ,
Please refer to the AN91162 datasheet for more information on creating a BLE custom profile. It provides an overview of custom profiles, services and characteristics and the procedure to build an application with PSoC 4 BLE using RGB LED control as an example. This application note describes the methodology for developing a BLE application with PSoC 4 BLE devices using a custom BLE profile.
Please let me know if this helps for your application.
