LSN50 is an open source project, developer can use compile their firmware for customized
applications. User can get the source code from:
Software Source Code:

Use Keil to open project file:
STM32CubeExpansion_LRWAN/Projects/Multi/Applications/LoRa/DRAGINO-LRWAN(AT)/MDK-
ARM/STM32L072CZ-Nucleo/Lora.uvprojx
In Keil, you can see what frequency band the code support.
1. If you want to change frequency, modify the Preprocessor Symbols.
For example, change EU868 to US915
