V3.3

6. Changelog

• General
  1. Added the support for LoRaWAN Class C devices.
  2. Implemented the radios errata note workarounds. SX1276 errata 2.3 "Receiver Spurious Reception of a LoRa Signal" is not yet implemented.
  3. Increased FSK SyncWord timeout value in order to listen for longer time if a down link is available or not. Makes FSK downlink more reliable.
  4. Increased the UART USB FIFO buffer size in order to handle bigger chunks of data.
• LoRaWAN
  1. Renamed data rates as per LoRaWAN specification.
  2. Added the support for LoRaWAN Class C devices.
  3. Handling of the MAC commands was done incorrectly the condition to verify the length of the buffer has changed from < to <=.
  4. Added the possibility to change the channel mask and number of repetitions trough SRV_MAC_LINK_ADR_REQ command when ADR is disabled.
  5. Corrected Rx1DrOffset management. In previous version DR1 was missing for all offsets.
  6. Changed confirmed messages function to use default datarate when ADR control is off.
  7. After a Join accept the node falls back to the default datarate. Enables the user to Join a network using a different datarate from its own default one.
  8. Corrected default FSK channel frequency.
  9. Solved a firmware freezing when one of the following situations arrived in OnRxDone callback: bad address, bad MIC, bad frame. (Pull request #10)
  10. Moved the MAC commands processing to the right places. FOpts field before the Payload and Port 0 just after the decryption. (Pull request #9)
  11. Weird conditions to check datarate on cmd mac SRV_MAC_NEW_CHANNEL_REQ (Pull request #7)
  12. Ignore join accept message if already joined (Pull request #6)
  13. Channel index verification should use OR on SRV_MAC_NEW_CHANNEL_REQ command (Pull request #5)
  14. Corrected the CFList management on JoinAccept. The for loop indexes were wrong. (Pull request #4)
  15. Correction of AES key size (Pull request #3)
