Just updated the Index Controller Firmware, so the exact procedure is:
- Edit
default.vrsettings
from
“Program Files (x86)\Steam\steamapps\common\SteamVR\resources\settings”
and set requireHmd to false (to avoid “no hmd” error)
"requireHmd": false,
-
make sure that
PiService.exe
pi_server.exe
PiServiceLauncher.exe
are not running (from task manager - taskmgr)
-
start SteamVR
-
Connect Index Controller with USB (even turned off)
-
wait for controller icon, no pairing needed, but icon MUST be the Index Controller icon and not the generic “C” icon
“i” circle means update is available, mouse over to icon and select update
