Hi, I have bought Beholder MS1 and was a little disappointed when I found out, it has only 8-bit controller. Anyway I connected it to my Mac, find proper SimpleBGC app (v 2.40b7) tried to install newer firmware 2.40b8. But it ended up with avrdude error nr.2 "No such file or directory". I noticed that there is only .exe file i avrdude folder. Is there an option to upgrade firmware on Mac?

And I also tried to connect te PID cotroller to my Android phone, I installed 8-bit app, connected via OTG cable but noting happened. The app doesn't read any value. I did find only option to connect via bluetooth (but Beholder MS1 doesn't have any bluetooth module, does it?).Is there any wa to get it working?
Thank you for your help.
