110 +This getting started example demonstrates how to design and deploy a simple display UI for the LTS5 device. The example includes:
79 79  
80 -Each PB01 is shipped with a worldwide unique set of LoRaWAN OTAA keys. To use PB01 in a LoRaWAN network, user needs to input the OTAA keys in LoRaWAN network server. After this, if PB01 is under this LoRaWAN network coverage, PB01 can join the LoRaWAN network and start to transmit sensor data. The default period for each uplink is** 20 minutes**.
112 +* Creating a basic UI with a single button.
113 +* Implementing functionality to navigate the Web UI to a new page when the button is clicked.
114 +* Uploading the UI to the LTS5 device.

209 -PB01 will send this uplink after Device Status uplink once join LoRaWAN network successfully. And it will periodically send this uplink. Default interval is 20 minutes and [[can be changed>>||anchor="H3.1A0DownlinkCommandSet"]].
249 +There are two common relationships between widgets: one is parallel, the other is parent-child. The parallel relationship means that widgets' relative position is based on a collective object of reference. In parent-child relationship, the parts of the child object that are outside the boundaries of the parent object are not visible by default. Therefore, we need to adjust the position of the child object so that it falls within the range of the parent object, allowing it to be seen as illustrated in image 13.
