Bluetooth GATT Service Reference
Human Interface Device (0x1812)
The HID Service exposes characteristics required for a HID Device to transfer HID report descriptors and reports to a HID Host. This also exposes the characteristics for a HID Host to write to a Device. The Human Interface Device Service is instantiated as a Primary Service.
