# IDs

Product information, device information, and devices can be identified by the following IDs.

Term Description Writing to the device
PSDI (Product Specific Device ID) Identifies a device in the real world. As the developer, you can set a unique optional value for each product. For example, you can include the manufacturing number or date in the PSDI, or use the PSDI for various other purposes. Required

# Register product information

When using the LINE Things Developer Trial, you'll work with a special type of product information called trial product information. Learn more from Creating trial product information in the LINE Things API reference.

While creating a trial product, you'll receive a service UUID for service search (serviceUuid), service UUID for device identification (psdiServiceUuid), and the characteristic UUID for device identification (psdiCharacteristicUuid).

# Configure the device

Configure your devices using the information you get when you create trial product information. Your devices must have the following information defined:

Item Description
Information for service search In the packet advertised by the device for pairing with your smartphone, include the service UUID for service search (serviceUuid).
Information for device identification In the characteristics that can be identified by the service UUID for device identification (psdiServiceUuid) and the characteristic UUID for device identification (psdiCharacteristicUuid), include the PSDI.

# System requirements for devices

To use a Bluetooth® Low Energy-compatible device with LINE Things, the device must meet these requirements:

  • The product has a unique GATT Service UUID (*) for product identification
  • Before bonding, the unique GATT Service UUID (*) of the product can be advertised
  • Bonding is enabled
  • The communication after bonding is encrypted
  • The PSDI can be read from the characteristics for device identification
  • In the characteristics for device identification, the attribute permission is set to Encryption.

*In LINE Things, we call this the service UUID for service search.
