Introduction ---------------- The aim of this project is to show an example of the endpoint LoRaWAN stack implementation. This LoRaWAN stack is an EU868 and US915 bands Class A and Class C endpoint implementation fully compatible with LoRaWAN 1.0.1 specification. Each LoRaWAN application example includes the LoRaWAN certification protocol implementation. SX1272/76 radio drivers are also provided. In case only point to point links are required a Ping-Pong application is provided as example. *The LoRaWAN stack API documentation can be found at: http://stackforce.github.io/LoRaMac-doc/* **Note 1:** *A port of this project can be found on [MBED Semtech Team page](http://developer.mbed.org/teams/Semtech/)* *The example projects are:* 1. [LoRaWAN-demo-72](http://developer.mbed.org/teams/Semtech/code/LoRaWAN-demo-72/) 2. [LoRaWAN-demo-76](http://developer.mbed.org/teams/Semtech/code/LoRaWAN-demo-76/) 2. System schematic and definitions ------------------------------------ The available supported hardware platforms schematics can be found in the Doc directory. 3. Acknowledgments ------------------- The mbed (https://mbed.org/) project was used at the beginning as source of inspiration. This program uses the AES algorithm implementation (http://www.gladman.me.uk/) by Brian Gladman. This program uses the CMAC algorithm implementation (http://www.cse.chalmers.se/research/group/dcs/masters/contikisec/) by Lander Casado, Philippas Tsigas. 4.

Usage --------- Projects for CooCox-CoIDE and Keil Integrated Development Environments are available. One project is available per application and for each hardware platform in each development environment. Different targets/configurations have been created in the different projects in order to select different options such as the usage or not of a bootloader and the radio frequency band to be used. 6. Changelog ------------- 2017-04-19, V4.3.2 * General (Last release based on LoRaWAN specification 1.0.1) 1. This version has passed EU868 and US915 LoRa-Alliance compliance tests. 2.
