RDR Firmware Changelog

All notable changes to the RD Firmware will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Versions marked with UPDATE! should not be used anymore.

[1.4.4] - 2021-11-23

This version corrects a problem where NFC reader has been blocked during LoRaWAN Uplink

[1.4.3] - 2021-10-15

This version corrects a small problem where hearbeats has occassionally sent multiple times.

[1.4.2] - 2021-09-03

This version corrects a problem with battery powered devices. Some devices did not properly detect the USB disconnect event so the battery powered mode was not enabled. This was leading to a very short battery life.

We let the device beep when there is an LoRaWAN error. This helps the user solve LoRaWAN issues before the battery gets empty.

[1.4.1] - 2021-08-16

This bugfix release corrects a problem with battery powered devices. It has been observed that sometimes the device does not turn off to save power, which may result in a shortened battery life.

[1.4.0] - 2021-06-02 - UPDATE!
