Report Clone config from old FLIRC to new FLIRC using 3.20.4? in General Questions Posted June 13, 2021 Well, I just received new Flirc USB dongle and can now answer my own questions. First, the old version of the software (3.20.4) I had installed on Windows 7 could not "see" the new dongle. Moreover, Windows 7 tried to find a driver for the new dongle when I inserted it. I knew that could not be right from what I've read here. It suggested that I needed to install the most current version (3.25.4) of the GUI. I installed 3.25.4 on Windows 7, started the GUI, and inserted the new dongle. The GUI continued to indicate that it was "not connected", but after a couple seconds, it alerted me that there was a new version of the firmware available. Thinking I had nothing to lose, I elected to install it. Installation was quick and painless. When the firmware upgrade was complete, the GUI indicated it was connected to the new dongle. So, I elected to load the working configuration file I had saved from the old dongle using 3.20.4. When I did that, the GUI indicated "data restored" (or something like that). I saved the resulting configuration. I just tested the new dongle and it works exactly like the old one. Just what I was hoping for. So the answers to my questions are 1) old versions of the GUI do not appear compatible with new versions of the dongle, but 2) configuration files from an old version of the GUI are recognized by the new version of the GUI and can be loaded into a new dongle with upgraded firmware. My experiment was pretty simple, and there could be situations in which an old configuration file is not compatible with the new GUI. To the extent that's true, I was lucky. I'm posting this in case it might be helpful to others.
