80 80  
81 -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.
