Is Nurage-VCA failing for you?
I have received reports about the NURAGE-VCA mode getting stuck in some of the Freak modules shipped recently.
Unfortunately, right now I'm traveling and I cannot test it. However, this model has been working fine in the past since I released version 3.1 of the firmware.
I think that the problem is caused by some difference in the firmware flashed in the recent modules. Even when it is the same code, I have built the firmware using a new computer and a more recent version of the GCC compiler.
If you are having this problem, please try re-flashing the old build of firmware 3.1 that you can find here: https://github.com/modlfo/VultFreakFirmware/releases/download/v3.1/FreakFirmware-3.1.zip
You can find information on how to update the module in the User Manual and you can also check the following video:
Please let me know if this works for you. I'll be preparing a new release of the firmware once I'm back home.
