This page describes different network configurations for connecting to the Raspberry Pi in the LoRa Plus™ Sales Demonstration Kit. Each configuration has different capabilities and requirements. Choose the configuration that best fits your needs.
Configuration 1: Direct Wi-Fi Connection
In this configuration, a laptop computer is connected directly to the Raspberry Pi via Wi-Fi. The computer connects to the "raspi-smtc-lan" Wi-Fi Access Point (AP) hosted by the Raspberry Pi.
Figure 1. Direct Wi-Fi Connection Configuration
Configuration Notes:
This configuration requires the time to be set via the command line. See the FAQ section on setting time for instructions.
The Raspberry Pi cannot be updated in this configuration because it has no internet connection.
To connect to the Wi-Fi AP, use the network name "raspi-smtc-lan" with the password "SemtecH!Lr2021".
Once connected, you can access the Raspberry Pi services using the local URL: rpi-lr2021-demo.local
Configuration 2: LAN Connection via Ethernet
In this configuration, both a laptop computer and the Raspberry Pi are connected to the same Local Area Network (LAN) via RJ45 Ethernet connections. This allows the Raspberry Pi to access the internet while maintaining local network connectivity.
Figure 2. LAN Connection via Ethernet Configuration
Configuration Notes:
The Raspberry Pi can be updated in this configuration because it has internet access via the LAN connection.
Its LAN IP address (e.g., 192.168.1.100 - check your router's DHCP table for the actual IP)
This configuration provides the best balance of local access and internet connectivity for updates.
Time synchronization will occur automatically via NTP if the LAN has internet access.
Configuration 3: Internet Connection via Ethernet
In this configuration, both a laptop computer and the Raspberry Pi are connected to separate local networks that provide internet access.
The Raspberry Pi is accessible only through its IP address on the internet.
This can be difficult if the local network that the Raspberry Pi is connected to does not provide a directly-addressable IP address (e.g., NAT configuration).
Generally speaking, this configuration is usually not recommended for most users due to the complexity of setting up and maintaining a fixed IP address for the Raspberry Pi.

Configuration Notes:
The Raspberry Pi can be updated in this configuration because it has internet access.
The Raspberry Pi can be addressed only through its IP address on the internet (not via the rpi-lr2021-demo.local URL).
To find the Raspberry Pi's IP address, you can:
Check your router's DHCP client list
Use network scanning tools
SSH into the device if you know its previous IP or use other discovery methods
This configuration is suitable for remote deployments where the Raspberry Pi is on a network with internet access.
Time synchronization will occur automatically via NTP.
