Architecture & Data Flow¶

Figure 1: 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 background, 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™ Modem & Geolocation Services
Keep the GNSS almanac up-to-date to ensure smooth GNSS operations.
Note
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 Modem & Geolocation Services.
