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

Architecture & Data Flow¶
LoRa Basics™ Modem-E works in the same manner as other end devices built with LoRa® chipsets. 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, the application server must forward uplinks and downlinks between the LoRaWAN® network server and the LoRa Cloud Device & Application Services.
