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**.
111 +* Creating a basic UI with a single button.
112 +* Implementing functionality to navigate the Web UI to a new page when the button is clicked.
113 +* Uploading the UI to the LTS5 device.

501 -== 2.9 Buzzer ==
464 +The project achieves the function of receiving LoRaWAN Class C messages and displaying them on the screen. Note: The Things Network (TTN) needs to enable Class C support, and the LA66 within the LTS5 needs to operate in Class C mode.
502 502  
466 +The downlink workflow proceeds as follows: The Things Network (TTN) sends a message in a specific format via downlink. Then, a LoRaWAN gateway relays this message to the LTS5. Finally, the LTS5 receives the message and displays it on its screen.
503 503  
504 -The PB01 has** button sound** and** ACK sound** and users can turn on or off both sounds by using [[AT+SOUND>>||anchor="H3.3A0Setbuttonsoundandbuttonalarm"]].
468 +The uplink workflow is as follows: The LA66 within the LTS5 sends a LoRaWAN message, for some reason, to a LoRaWAN gateway, which then forwards it to The Things Network (TTN).
505 505
