At SODAQ one of the engineers had a novel idea to simplify the firmware updating of the RN2483.
Instead of using a programmer or the java based tool Microchip provides, you can now upload an Arduino sketch that parses the HEX file and writes it to the RN2483. It takes about 30 seconds.
We tested it and it works well on the SODAQ Autonomo, SODAQ ONE and the SODAQ ExpLoRer.
We have published this tool on Github. We'd like to hear your feedback!
