+     * @param[ref] _ble
+     *                BLE object for the underlying controller.
+     * @param[in] manufacturersName
+     *                This characteristic represents the name of the
+     *                manufacturer of the device. The name is copied into the
+     *                BLE stack during this constructor.
+     * @param[in] modelNumber
+     *                This characteristic represents the model number that is
+     *                assigned by the device vendor. The value is copied into
+     *                the BLE stack during this constructor.
+     * @param[in] serialNumber
+     *                This characteristic represents the serial number for a
+     *                particular instance of the device.  The value is copied
+     *                into the BLE stack during this constructor.
+     * @param[in] hardwareRevision
+     *                This characteristic represents the hardware revision for
+     *                the hardware within the device. The value is copied
+     *                into the BLE stack during this constructor.
+     * @param[in] firmwareRevision
+     *                This characteristic represents the firmware revision for
+     *                the firmware within the device. The value is copied
+     *                into the BLE stack during this constructor.
+     * @param[in] softwareRevision
+     *                This characteristic represents the software revision for
+     *                the software within the device. The value is copied
+     *                into the BLE stack during this constructor.
+     * @param[in] pnpID
+     *                This characteristic represents HID-specific information,
+     *                such as vendor id, product id and version.
