LoRa® is a wireless modulation technique designed to allow low-power end-devices to communicate over long range and at low data rates. LoRaWAN is a wireless networking protocol which operates over LoRa communication layer and acts as Medium Access Control (MAC) layer. LoRaWAN specification and its development is overseen by LoRa Alliance™. The specification is meant for secure communication of end-devices and ensures inter-operability within the LoRa network. Microchip LoRaWAN Stack is Opened for SAM R34 IC and WLR089U0 Module where MAC and Radio layers are both provided as source code for self-support and self-maintenance. MLS v2.0.0 release is pre-tested against LoRaWAN 1.0.4 Class A using official LoRa Alliance Test Tool (LCTT). ## Hardware Platforms * Purchase the [SAM R34 Xplained Pro Evaluation Kit](https://www.microchip.com/en-us/development-tool/DM320111)

* Purchase the [WLR089U0 Xplained Pro Evaluation Kit](https://www.microchip.com/en-us/development-tool/EV23M25A)

* Purchase a LoRa Gateway * If using a Join Server with security solution for LoRaWAN, a pre-provisioned ATECC608 secure element is required. Purchase the Trust&GO secure element [ATECC608B-TNGLORA](https://www.microchip.com/en-us/product/ATECC608B-TNGLORA) for TTI Join Server or the [ATECC608B-TNGACT](https://www.microchip.com/en-us/product/ATECC608B-TNGACT) for Actility Join Server and the [CryptoAuthentication Socket Kit](https://www.microchip.com/en-us/product/ATECC608B-TNGLORA) ## LoRaWAN Certification Test Tool The LoRa Alliance® has developed a LoRaWAN® Certification Test Tool (LCTT) for all LoRa Alliance® device manufacturers to pre-test their devices before sending them to the Authorised Test Houses (ATHs) for formal LoRaWAN® Certification testing. The LoRaWAN® certification tests for end node functionality, in other words it tests that node’s LoRaWAN protocol stack and application are compliant with the LoRaWAN specification. Checkout the [LoRa Alliance](https://lora-alliance.org/lorawan-certification/) for more details.

The present software has been PRE-TESTED against the LoRaWAN® L2 Specification 1.0.4 (Class A only) for the following regions: - EU863-870
- US902-928

 And using the following setup: - LCTT version: LCTT v3.1.0_D1 | GUI v1.10.0 - Gateway(s) used for EU campaign (OTAA, ABP): Picocell GW and Semtech GW (Picocell GW for all tests except SF12 steps) - Gateway(s) used for NA campaign (OTAA, ABP): Picocell GW - SAMR34 Xplained Pro Rev 4 - WLR089U0 Xplained Pro Rev A/01 - All testing have been done in Application mode using the **LoRaWAN Mote Application** since the LoRaWAN 1.0.4 test specification elaborated and standardised the command communication between the test Network Server and the test End Device. > For reference, checkout the folder `MLS_SDK_2.0.0_Release/LCTT_TestReports` and get access to the test reports. ## Package Overview The Microchip LoRaWAN Stack contains: * **LoRaWAN Enddevice Demo (with certification mode & pre-provisioned ATECC608 support)**: A 32-bit MPLAB Harmony 3 Project, which provides a reference application * **RN-style Parser**: A 32-bit MPLAB Harmony 3 project * The LoRaWAN stack components in source code * Drivers, software timer, PDS, PMM and radio drivers for the LoRaWAN stack * The facility to support dynamic regional band switching within the supported bands The applications are located in `lorawan_h3_apps` folder and organized as below: ```bash lorawan_h3_apps/ ├───enddevice_demo/ │ └───sam_r34_xpro/ │ └───firmware/ │ ├───enddevice_demo_sam_r34_xpro.X/ │ └───src/ ├───parser │ └───sam_r34_xpro/ │ └───firmware/ │ ├───parser_sam_r34_xpro.X/ │ └───src/ └───parser_ecc608 └───sam_r34_xpro/ └───firmware/ ├───parser_sam_r34_xpro.X/ └───src/ ``` Checkout the [Application Release Notes](MLS_SDK_v2.0.0_Release/Harmony_LoRaWAN_MLS_2_0_0/lorawan_h3_apps/release_notes.md#top) 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) The APIs and the stack attributes are described in the [SAM R34-R35 Microchip LoRaWAN Stack Software API Reference Manual](https://www.microchip.com/en-us/product/ATSAMR34J18#document-table). ### LoRaWAN Stack Directory Structure The following table provides the directory structure of the LoRaWAN stack code base (`src/config/default/MLS`). | Directory | Description | | --------- | ----------- | | `/common` | Contains the commonly included files(s) | | `/hal` | Contains the implementation for the radio hardware interface, timers, etc | | `/module_config` | Contains the `conf_***.h` for PMM, Radio, Regional parameters, SAL, stack and SW Timer modules | | `/pmm` | Contains the Power Management Module (PMM) | | `/private` | Contains the sources of the LoRaWAN MAC layer specification independent of regional parameters | | `/regparams` | Contains the implementation of the MAC layer functionality specific to the regional bands | | `/sal` | Contains the Security Abstraction Layer (SAL) | | `/services` | Contains modules scuh as software timer, PDS and AES | | `/sys` | Contains system modules such as task manager, power management and initialization | | `/tal` | Contains transceiver related headers and sources, drivers for supported transceivers | ### Difference from ASFv3 1. Application configuration macros are located at `configuration.h` instead of `conf_app.h` 2. Most of the compiler input symbols (i.e., -DXXXX in gcc command line) are moved to `conf_***.h` and `configuration.h` as macros 3. Same enddevice_demo application project can be configured to work with or without ECC 4. `ENABLE_PDS=1` and `BOARD_SAMR34_XPRO` are only created by application and present as compiler input symbols 5. By default `CRYTPO_DEV_ENABLED` is disabled i.e., ECC is not enabled 6. By default SAMR34 XPRO is configured to read DevEUI from EDBG 7. `enddevice_demo.c` is split into `enddevice_demo.c` and `mls_app.c` 8. `mls_app.c` is the common application template automatically generated from MHC 9. `mls_app.c` has commonly needed lorawan application functionalities such as initialization, join, uplink, sleep management, certification commands etc. 10. `enddevice_demo.c` contains ONLY the menu driver for the user interface ## Software Environment Setup 1.

You can see the version dependencies of the demo in `harmony-manifest-success.yml` found at `src/config/default` into Harmony Content Manager.
In case of a missmatch between the Harmony 3 components present in the demo and the ones available in disk, Harmony Configurator will popup a warning screen during launch.
> Simply ignore the warning related to `lorawan_h3_sources` folder

9. After the synchronization, the Harmony framework folder `Harmony_LoRaWAN_MLS_2_0_0` (dedicated for LoRaWAN development) should contain the following directories.
