I just installed a brand new Sequre 70a ESCape32 ESC in my Class 2 build and while changing the setting via the WiFi programmer I ctrl C, ctrl V'd a bit of code to have it play the Back To The Future theme song on startup. Flashed the changes and unplugged the ESC. When plugging the battery back in it played one note and then the 3 battery confirmation tones. I unhooked everything and checked the programming just to be sure that it did save the changes and it had. The entire music code was in there but when you enter it in the music tab to test it you only get one tone, no matter what is entered. I googled the issue and there was one Reddit comment with the same issue from 4 months ago with one reply that led me to a discord server that didn't address the issue either. I did read that there was a bug in ver11 of the firmware so I tried to update to rev12.1 but after that failed I checked and my ESC has rev13 firmware already installed which I assume already has the patch from 12.1. Anyone have any clue what is going on with this ESC? Thanks in advance!
