Transcript

1. UKRIT PONGSATHAPORN Lead Hardware Engineer LINE THAILAND LINE THINGS CONNECTING THE UNCONNECTABLE
2. A brief look at previous IoT solutions What you can do right now Something New ? LINE THINGS History Developer Trial ???
3. HISTORY
4. Messaging API
5. LINE Messaging API IoT Use Case IoT device LINE server Device directly connects with a third party web Messaging API Your server
6. LINE BEACON
7. LINE Beacon LINE LINE server Your server LINE BEACON Messaging API
8. FEATURES Relative location of the user to the beacon Segment and specify only users that are near your designated area Provide a more relevant and useful service Location Segmentation Relation
9. GOING FURTHER Two-way communication
 Data can be sent and received Support for almost all BLE devices Seamless integration for users. Out of sight, out of mind. Bi-directional Full Support Seamless
10. A universal platform for IoT devices
12. WHAT IS LINE THINGS ? A n I o T p l atfo r m w i t h i n L I N E ’s ecosystem, open to everyone A bridge to connect users, devices, and services Universal hub for your IoT devices and online services Open IoT Platform Bridge to Connect Universal Hub
13. LINE THINGS LINE LINE server Device Messaging API LIFF BLE Your server LIFF app
14. CONNECTION PROCESS Device Scanning Connect Advertising
15. DEVICE LINK LIFF BLE
16. HOW DOES LIFF BLE WORK ? LINE LIFF SDK (BLE plugin) BLE native component Device LIFF app
17. function initializeApp() { liff.init(() => initializeLiff(), error => uiStatusError(makeErrorMsg(error), false)); } function initializeLiff() { liff.initPlugins(['bluetooth']).then(() => { liffCheckAvailabilityAndDo(() => liffRequestDevice()); }).catch(error => { uiStatusError(makeErrorMsg(error), false); }) } IMPLEMENTATION
18. function initializeApp() { liff.init(() => initializeLiff(), error => uiStatusError(makeErrorMsg(error), false)); } function initializeLiff() { liff.initPlugins(['bluetooth']).then(() => { liffCheckAvailabilityAndDo(() => liffRequestDevice()); }).catch(error => { uiStatusError(makeErrorMsg(error), false); }) } IMPLEMENTATION
19. 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(); IMPLEMENTATION
20. 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
21. Characteristic: Read Characteristic: Read Characteristic: Write Characteristic: Notify Characteristic: Read Characteristic: Write Characteristic: Notify BLUETOOTH STACK Service:LINE Things Trial Service:Custom1 Service:Custom2
22. 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(); DATA ACCESS
23. Device Read Device Write Device Notify DATA ACCESS LINE app LINE app LINE app
24. 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(); READ
25. 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') ) WRITE
26. 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(); NOTIFY
