I'm running on a windows 11 computer trying to locate the 300RI via a USB to uart connection. I have fully checked the wiring and cross referenced with other forum posts. I have tried the python tool, the desktop app, and platfomio aceinna extension. All were unable to find the 300RI but when I check the serial it is outputting 0xfffd on repeat, is this an error code or is there a fix.
