21. How Does LIFF BLE Work?

22. Implementation const device = await liff.bluetooth.requestDevice(); const gatt = await

    device.gatt.connect(); const service = await gatt.getPrimaryService( 'E625601E-9E55-4597-A598-76018A0D293D' ); 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();

23. const device = await liff.bluetooth.requestDevice(); const gatt = await device.gatt.connect();

    const service = await gatt.getPrimaryService( 'E625601E-9E55-4597-A598-76018A0D293D' ); const characteristic = await service.getCharacteristic( '26E2B12B-85F0-4F3F-9FDD-91D114270E6E' ); const value = await characteristic.readValue(); Connection Process

25. Data Access const device = await liff.bluetooth.requestDevice(); const gatt =

    await device.gatt.connect(); const service = await gatt.getPrimaryService( 'E625601E-9E55-4597-A598-76018A0D293D' ); const characteristic = await service.getCharacteristic( '26E2B12B-85F0-4F3F-9FDD-91D114270E6E' ); const value = await characteristic.readValue();

26. Read const device = await liff.bluetooth.requestDevice(); const gatt = await

    device.gatt.connect(); const service = await gatt.getPrimaryService( 'E625601E-9E55-4597-A598-76018A0D293D' ); const characteristic = await service.getCharacteristic( '26E2B12B-85F0-4F3F-9FDD-91D114270E6E' ); const value = await characteristic.readValue();

27. Write const device = await liff.bluetooth.requestDevice(); const gatt = await

    device.gatt.connect(); const service = await gatt.getPrimaryService( 'E625601E-9E55-4597-A598-76018A0D293D' ); const characteristic = await service.getCharacteristic( '26E2B12B-85F0-4F3F-9FDD-91D114270E6E' ); await characteristic.writeValue( new TextEncoder(‘utf-8‘).encode(‘LIFF BLE’) );

28. Notify const device = await liff.bluetooth.requestDevice(); const gatt = await

    device.gatt.connect(); const service = await gatt.getPrimaryService( 'E625601E-9E55-4597-A598-76018A0D293D' ); 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();
