# Configuring devices
In the LINE platform, you'll first register product information. You'll then use this product information to configure devices.
|Product||A combination of hardware and software features you want to bring to users. e.g. LINE CLOVA.|
|Device||A piece of Bluetooth® Low Energy-compatible hardware configured to be able to link with LINE. See also Configure the device.|
|Product information||A database entry that represents a product in the LINE database. See also Registering product information.|
|Device information||A database entry that represents a device in the LINE database. Whenever a user links a new device with LINE, new device information is automatically created in the LINE Platform.|
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 |
Write it in the characteristics for identification of a device.
|Product ID||Identifies an instance of product information in the LINE database. Issued when the product information is created.||Not required|
|Device ID||Identifies an instance of device information in the LINE database. Issued when the user links a device.||Not 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 (
# 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:
|Information for service search||In the packet advertised by the device for pairing with your smartphone, include the service UUID for service search (|
|Information for device identification||In the characteristics that can be identified by the service UUID for device identification (|

# 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.
