[3.2.0] - 2015-04-30

General

Release based on “LoRaWAN specification 1.0.0”
GitHub reported issues corrections

Added

Added the support of packed structures when using IAR tool chain
Added a function to get the time in us
Added a typedef for time variables (TimerTime_t)
Added a function that returns if the GPS has a fix or not
Added missing MAC commands and updated others when necessary

- 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
Added the possibility to chose to use either public or private networks

```
0: LED off
1: LED on
```
The node transmits periodically on port 1 the LED status on 1st byte and the message “Hello World!!!!” the array looks lik
```
 { 0, 'H', 'e', 'l', 'l', 'o', ' ', 'W', 'o', 'r', 'l', 'd', '!', '!', '!', '!' }
```
