Lora Clients firmware for Airfy Mini and Airfy Things

=====================================

1. 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 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 version 3.x API to version 4.x API wrapper is available. Applications built using version 3.x API should work without modifications except that one must include LoRaMac-api-v3.h instead of LoRaMac.h file

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. Dependencies

This program depends on specific hardware platforms. Currently the supported platforms are:

- Airfy Things
    MCU     : nRF51822 
    RADIO   : SX1276
    ANTENNA : MMCX connector
    BUTTONS : Reset, General purpose button
    LEDS    : RGB
    SENSORS : SeeedStuidio Grove Compatible
    GPS     : No
    SDCARD  : No
    EXTENSION No
    REMARK  : Powered by two AAA battery

5. 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.
