CC2640R2F: Advertisement service data

Mariano

Part Number: CC2640R2F

Hello everyone;

I need to add advertisement service data in my project in order to identify which model of my product I am connecting in before to perform a connection. I think two bytes in advertisement service data is sufficient.

My project uses CC2640R2F with stack 4.x of bluetooth.

Please, could anyone help me?

    I can use GAP_ADTYPE_SERVICE_DATA_32BIT or GAP_ADTYPE_SERVICE_DATA_128BIT in advertData[].


    Are there some example?

    Hi,

    I highly recommend referencing the Scanning & Advertising SimpleLink Academy lab. This module provides information on how to set up scanning and advertising. Advertising Task 2 specifically shows how to change advertising data in a ble4 example.

    Best Regards,

    Jan

    Ok, I know how to change the advertising and response data. My doubt is specifically about GAP_ADTYPE_SERVICE_DATA_*

    The module from SimpleLink Academy lab not have any mention of GAP_ADTYPE_SERVICE_DATA_* and I unable to find samples related to that.

    static uint8_t advertData[] =
{

  // ... another stuffs

  0x05,
  GAP_ADTYPE_SERVICE_DATA_32BIT,
  LO_UINT16(SIMPLEPROFILE_SERV_UUID),
  HI_UINT16(SIMPLEPROFILE_SERV_UUID),
  0x2,
  0x3,
};

    My attempt is to add the code above but I cant capture the service data in android application.
