General

  • Release based on "LoRaWAN specification 1.0.4" and "LoRaWAN Regional Parameters 2-1.0.1"
  • GitHub reported issues corrections.

Known limitations

  • SAMR34 platform does not support NVM storage. This is a requirement for LoRaWAN versions greater or equal to 1.0.4.
    No work on this subject is forseen by the maintainers. Implementation proposals are welcome.

Added

  • Added possibility to override periodic-uplink-lpp example LORAWAN_DEFAULT_CLASS
  • Added I2C driver support for B-L072Z-LRWAN1 and Nucleo platforms to the build system
  • Added battery voltage and MCU temperature reading functions implementation for Nucleo platforms
  • Added a default value for Request->ReqReturn.DutyCycleWaitTime to ensure that a valid value is always returned
  • Added SX126x REG_RX_GAIN and REG_TX_MODULATION to the radio registers retention list
  • Added SX126x missing registers definitions
  • Added radio image calibration enforcement after radio initialization and radio sleep cold start.
  • Added possibility to query minimal Tx data rate

Changed

  • Updated ADC driver based on en.en-st-stm32cubeide examples
  • Changed improved the way LmHandler handles the packages transmissions
  • Changed certification OnTxPeriodicityChanged callback implementation in order to directly apply the requested change
  • Changed the LmHandler initialization to apply user default data rate
  • Changed SX1272 and SX1276 FSK FIFO threshold from 15 to 31 in order to give more time for the MCU to make other processing tasks
  • Changed the way IrqFired global variable is handled by RadioIrqProcess
  • Changed the place of call to TimerStop( &RxTimeoutTimer ) on RadioIrqProcess implementation
  • Changed utilities.h SUCCESS/FAIL definition by an enumeration LMN_STATUS_OK/LMN_STATUS_ERROR

Fixed

  • Fixed Null pointer exception when CN470 region was selected
  • Fixed src/system/gps.c HasFix variable type from double to bool
  • Fixed Class C downlink handling
  • Fixed I2C driver for L476
  • Fixed re-transmissions handling when ClassB or ClassC downlink is received
  • Fixed certification FPort224DisableReq command NVM handling
  • Fixed Class B & C confirmed downlink acknowledge management when CLASS_B_C_RESP_TIMEOUT expires
  • Fixed an issue when receiving downlinks in class C window during a class A procedure
  • Fixed SX126x and LR1110 driver IrqFired variable management
  • Fixed LmhpCompliance.c periodicity array size computation
  • Fixed join back-off by not storing band usage on the NVM memory.
  • Fixed LoRaMacMibGetRequestConfirm MIB_SE_PIN handling
  • Fixed ping-slot frequency to take in account the AS923_FREQ_OFFSET_HZ parameter
  • Fixed fragmentation loop variable type in order to allow more than 255 fragments
  • Fixed RtcMs2Tick conversion on SAMR34
  • Fixed compiling issue when RU864 region is selected
  • Fixed MLME_SCHEDULE_UPLINK handling.

Removed

  • Removed STM32 platforms system wake up time calibration
