ios app and (Bluetooth hardware) ble hid interactive data?

I have a project that requires interactive data between the ios app and ble hid. How do I get the hid data and how do I set the hid data? What preparation is required to develop hid? Do you want to apply to Apple for opening hid service? How do you do it?
