Hiroo Takaku LINE / Developer Product Department LINE has been developing services and platforms that enable communication between people and things that bring discoveries and create new values through connectivities between everyday devices and LINE app and Clova. This session showcases LINE's effort in IoT, including connectivity with home appliances and devices using BLE (Bluetooth Low Energy), along with an introduction of new third-party developer product. Other topics include Clova Home (for connectivity with IoT/IR home appliances) and LINE app developer product for connectivity with BLE devices. Demonstration on development and implementation of LIFF BLE, a feature to be provided in developer product, will also be presented. *LIFF BLE enables BLE communication within LINE Front-end Framework. This session is targeted for audiences interested in IoT, LINE app, and Clova. Anyone, including entry-level developers, is encouraged to attend.

const gatt = await device.gatt.connect();
const service = await gatt.getPrimaryService(

const characteristic = await service.getCharacteristic(
'26E2B12B-85F0-4F3F-9FDD-91D114270E6E'
);
characteristic.addEventListener('characteristicvaluechanged', (e) => {
console.log('value changed to:' + e.target.value);
});
await characteristic.startNotifications();
