LoRa Basics™ Modems: Walk-through
This guide will walk you through the steps required for an end-to-end demonstration of Semtech’s portfolio of LoRa Basics™ for end nodes and will explain how to set up all required servers. It also provides several sample applications.

Architecture & Data Flow¶
LoRa Basics™ Modem-E works the same as other LoRa®-based end devices. All traffic related to device management occurs at the application layer (default port: 199). In the backround, the modems use this traffic to:
Update data selected by the user, such as the power consumption and the reset counter
Answer requests triggered by an API call to the LoRa Cloud™ Device & Application Services
Keep the GNSS almanac up-to-date to ensure smooth GNSS operations.
Because all device management traffic happens at the application layer, it is the responsibility of the Application Server to forward uplinks and downlinks between the LoRaWAN® Network Server and the Device & Application Services.
