    how to discover all characteristic descriptors

    ZhaohuaS_76

      HW: BCM20736

      SDK: 2.1.1

      Question:

      I use the BCM20736 as a central device, central need to discover all the servcies/characteristics/descriptors of the client.

      As Core 4.1 spec-Vol3-PartG-Chapter4 said,  use the Read-By-Group-Request to discover all primary/second services and all characteristics of special service, use the Find-Information-Request to discover all characteristic descriptors.

      I can find the API "bleprofile_sendReadByGroupTypeReq" for Read-By-Group-Request, but I can't find the API for Find-Informaiton-Request, how to discover all characteristic descriptors?
