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.
522 522  
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.
523 523  
524 -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).
525 525  
526 -* (% style="color:#4f81bd" %)**Button sound**(%%)** **is the music produced by the node after the alarm button is pressed.
