651 +The LPS8V2 is already set to connect to Chirpstack. So what we need to do now is only configure register these devices to Chirpstack:

652 -This example assumes users already have:
653 653  
654 -* SN50v3-LB register on ChirpStack server already
655 -* The user is able to see the data on the ChirpStack server device page.
