Explanation:
Box 1: ID Scope
In the Azure portal, select the Overview blade for your Device Provisioning service and copy the ID Scope value. The ID Scope is generated by the service and guarantees uniqueness. It is immutable and used to uniquely identify the registration IDs.
Box 2: Global device endpoint
The global_prov_uri variable, which allows the IoT Hub client registration API IoTHubClient_LL_CreateFromDeviceAuth to connect with the designated Device Provisioning Service instance.
Example code:
static const char* global_prov_uri = "global.azure-devices-provisioning.net"; static const char* id_scope = "[ID Scope]"; Reference:
