    Are all services required in the Advertisement Packet?

      I'm new to BLE so forgive me. Do all custom services need to be listed in the advertisement packet? I have an application wit a custom service and the Device Information Service. If I remove the Device Information Service from the advertisement packet, CySmart on my Android still seems to know that it's there. How?


      I am developing an embedded peripheral as well as a matching smartphone app. If both the 4200BLE and the smartphone know the UUIDs, is it necessary to advertise them in the advertisement packet?
