Advanced Configuration Options
The config.ini file can take several options which may be useful for troubleshooting or
dealing with hardware malfunctions and special situations.
bt_pin=nnnn – Sets the Bluetooth PIN to the specified 4-digit code.
gamma_correction=true/false – The hoop normally has gamma correction enabled (
γ
=
2.2)
. This helps keep images from looking washed out and makes them more closely
match what you see on the screen. You can disable gamma correction if you need linear
brightness response for some reason.
disable_charger=true – Hoop ignores external charging and power signals. Use this
option if the hoop shows a single green or yellow LED when not connected to power, or if
you want to display patterns while powering the hoop via USB. Holding the POWER
button has the same effect until the hoop is restarted.
disable_sensors=true – Motion sensors are ignored and all motion-related functions are
disabled.
skip_bad_led=n – Disables a single specified LED. Use this if one or more emitters on an
LED fails and it’s displaying incorrect colors. LED 0 is the first LED on the end of the hoop
with the USB port. This is just a temporary measure to reduce the appearance of a bad
LED.
allow_downgrade=true
–
If for some reason you need to go back to a previous firmware
version, setting this option will allow you to load a version older than what's currently
loaded. Don't set this option with more than one firmware file present, or the hoop will get
stuck in a loop until the extra files are deleted.
ignore_low_battery=true – Setting this option will cause the hoop to keep running until the
battery voltage is too low to continue. Use this only if you're having trouble with the hoop
shutting off prematurely, and be sure to take the battery out as soon as the pattern starts
to freeze or turn red/orange.
disable_ir_credentials=true – Set this option to prevent the hoop from sharing its WiFi
connection information over IR.
frame_rate=n – Sets the desired frame rate in frames per second. If this is set too high, the
hoop will automatically reduce the setting to the maximum frame rate possible for the
configured number and type of LEDs. Hoops default to this maximum rate. In some
cases, particularly for users with photosensitive epilepsy, it may be desirable to lower this
setting to reduce the potential for strobe effects.
