    Hi Dev,

    You can simply change tha advertData[] variable. You should read about the format of advertisements here: dev.ti.com/.../

    Thank you Marie, I came across static uint8 advertData[] function in simple_broadcaster.c in application folder of app, and when I change the data there observations can be made. But I cannot send the UUID by this too, the UUID which is mentioned below the GAP_ADTYPE_MANUFACTURER_SPECIFIC I want to transmit this.

    Hi Dev,

    to do this, you should add BEACON_FEATURE to the list of compiler predefines (Project-> Properties-> Build -> ARM Compiler -> Predefined Symbols.)
