LoRaWAN endpoint stack implementation and example projects.
=====================================
1. Introduction
----------------
The aim of this project is to show an example of the endpoint LoRaWAN stack implementation.
This LoRaWAN stack implements all regions defined in "LoRaWAN Regional Parameters v1.0.2rB" document. Class A and Class C endpoint implementation
is fully compatible with "LoRaWAN specification 1.0.2".
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/*

---------
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.

when all the operations are finished.
When a ClassA Tx cycle starts a timer is launched to check every second if everything is finished.
* Added a new parameter to LoRaMacEventFlags structure that indicates on which Rx window the data has been received.
* Added a new parameter to LoRaMacEventFlags structure that indicates if there is applicative data on the received payload.
* Corrected ADR MAC command behavior
* DutyCycle enforcement implementation (EU868 PHY only)
**REMARK 1** *The regulatory duty cycle enforcement is enabled by default
which means that for lower data rates the node may not transmit a new
frame as quickly as requested.
The formula used to compute the node idle time is*
*Toff = TimeOnAir / DutyCycle - TxTimeOnAir*
*Example:*
*A device just transmitted a 0.5 s long frame on one default channel.
This channel is in a sub-band allowing 1% duty-cycle. Therefore this
whole sub-band (868 MHz - 868.6 MHz) will be unavailable for 49.5 s.*
**REMARK 2** *The duty cycle enforcement can be disabled for test
purposes by calling the LoRaMacSetDutyCycleOn function with false
parameter.*
* Implemented aggregated duty cycle management
* Added a function to create new channels
* Implemented the missing features on the JoinAccept MAC command
* Updated LoRaMacJoinDecrypt function to handle the CFList field.

compiler option from Keil projects. Added own __ffs function
implementation to utilities.h file.
