Hum, that's a weird issue x)
if you get around to it, the issue is the code youre using for connection to buttplug.io might be using a specific number item in the initface list of connected devices, even if theyre disconnected. I cannot remember the game but another one had this issue where if your toy wasnt the VERY first one in the list of numbers initface assigns to devices you connect, it wont connect to the correct one.
For example -
connect a lush (gets index 0)
connect a gush (gets index 1)
(etc.)
(etc.)
these are then assigned a number for indexing (somewhere, idk where, config file)
if i want gush to be the one that works, i need to remove both from the connected, saved devices, then re scan for the gush as a new device, so it gets "index: 0"
Hopefully this helps. Im not code literate, ive jus seen the issue recently elsewhere. Fun doom-like. Keep up the good work o7
