Profiles Identification

Interesting question. The lack of a profile identifier (presumably a uuid) implies that if a profile spec says X,Y,Z services are mandatory and they exist, then by implication that profile is in operation.
However, if another profile is ever created with those same mandatory services, then you have ambiguity.
Because a profile spec defines how those set of services behave as a group.

Hence if your GATT client really needs to know one way or the other, you could add a custom service that has no characteristics but is just a place holder to 'flag' that certain profile exists.

Perhaps. Can you elaborate what you are after, and what you mean by a "profile identifier" (since the concept does not exist in the BLE specification)?

Ok Thanks for the Support.
Is there any possibility to add profile identifier in the further versions of SDK?
Can we make a suggestion to add features in the SDK somewhere in Nordic Support??

No, there is no profile identifier. You just need to include all the services from both the profiles you want to support.

Thanks Einar for your reply.

Now I am clearing what I want to look for.

When we are making an application based on two profiles for example Heart Rare Profile and Battery Indication Profile.

In this situation, is there any profile identifier in nRF51 SDK/nRF52 SDK to identify the services belongs to which profile?

Hi,

I am not sure exactly what you are looking for? There is no profile identifier per se. A BLE profile is simply a collection of services. However, the standard profiles are defined by the Bluetooth SIG and you can find all information (specifications) about them here.
