V3.2

6. Changelog

General
1. Updated LoRaMac implementation according to LoRaWAN R1.0 specification
2. General cosmetics corrections
3. Added the support of packed structures when using IAR tool chain
4. Timers: Added a function to get the time in us.
5. Timers: Added a typedef for time variables (TimerTime_t)
6. Radios: Changed the TimeOnAir radio function to return a uint32_t value instead of a double. The value is in us.
7. Radios: Corrected the 250 kHz bandwidth choice for the FSK modem
8. GPS: Added a function that returns if the GPS has a fix or not.
9. GPS: Changed the GetPosition functions to return a latitude and longitude of 0 and altitude of 65535 when no GPS fix.
LoRaWAN
1. Removed support for previous LoRaMac/LoRaWAN specifications
2. Added missing MAC commands and updated others when necessary
  - Corrected the Port 0 MAC commands decryption
  - Changed the way the upper layer is notified. Now it is only notified
    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 behaviour
  - 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
    
    Eaxample:
    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.
3. Due to duty cycle management the applicative API has changed.
  All applications must be updated accordingly.
4. Added the possibility to chose to use either public or private networks

v3.1

01d731f

v3.1

Note

Next version of the project will include big changes.

This is the last version based on the Semtech LoRaMac implementation. The next
version will be based on the IBM 'LoRaWAN in C'
implementation.

The IBM 'LoRaWAN in C' implementation adds the support of the Class A endpoint
fully implemented and Class B endpoints.

The biggest change resides on the MAC layer API which is completely different.
