Creating a BLE Custom Profile
4. On the Profiles tab, configure profile-specific parameters. The Component exposes services, characteristics, and
descriptors in the form of a profile tree, as shown in Figure 12.
No changes are required in the Generic Access and Generic Attribute services.

6. Click the RGB LED service on the service tree and set the UUID format for your custom service as 128-bit, as shown in
Figure 14. This UUID is used by the GATT client device to recognize the attribute present within the GATT server device.
Note The default 128-bit UUID value seen in the Component (00000000-0000-1000-8000-00805F9B34FB) is the base
UUID defined by the BLE SIG that is used to calculate the complete 128-bit UUIDs from 16-bit and 32-bit UUIDs.
The BLE SIG recommends using a 128-bit UUID, different from the base UUID, for custom attributes to ensure that it
does not conflict with existing UUIDs for standard services.
