Figure 1. device list If you want to re-scan all the BLE devices, click the refresh button on the up-right corner of the page. Figure 2. refresh button 3.4 Connect/Disconnect Smart HMI Device In the device list page, there will be several items that is scaned BLE devices. You could make the app to connect the BLE device by clicking the button on the right of the item.
Figure 3. connect button in the device list page Once the app connects to the BLE device, it will turn to connected page automatically. Figure 4. connected page Click the connected device item, it will change to operate page so that you could operate the HMI menu of the smart HMI device.

Figure 5. disconnect button in the connected page 3.5 Operate Smart HMI Device Once the app enters operate page, the screen shows like below: Figure 6. operate page There are up/down and left/right buttons to operation the HMI menu once you click the buttons.
Since there are both app HMI and physical HMI, in order to keep hmi alive for each click operation at a time, the logic is that physical HMI has higher priority than app HMI. If app HMI wants operation on the buttons, the app need tell physical HMI that I want to operation in app HMI, then physical HMI will give the permission to app HMI. So there is enable/disable button to get the permission from physical HMI. Figure 7. enable key button 3.
