SAM R34/R35 Microchip LoRaWAN™ Stack Software API

Reference Manual

Introduction

Microchip LoRaWAN Stack (MLS) Software API provides an interface to the different software modules. This

document describes how to configure and enable functionalities of the API software. A general description of each

API is provided including the functionalities, syntax, responses, and an example. The API description defines the

parameter with its type, range (valid /acceptable values), the default value (when available), and the factory-

programmed value (when applicable).

Default value is set automatically if the parameter is omitted and at the software reset (if the command setting is not

stored in NVM). The factory-programmed value is set at the software reset when the setting is not modified with

respect to the manufacturer setting; it is valid for the commands that store the setting in Nonvolatile Memory (NVM).

MLS provides APIs for following software modules:

• LoRaWAN MAC Layer (MAC)

• LoRaWAN Radio Layer (TAL)

• Persistent Data Server (PDS)

• Power Manager Module (PMM)

• Hardware Abstraction Layer (HAL)
