[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

    • Corrected the Port 0 MAC commands decryption

    • 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.

    • Added a function to create new channels

    • Implemented the missing features on the JoinAccept MAC command
