Give more information if you have

Currently used command sudo linux-enable-ir-emitter --device /dev/video2 --width 640 --height 360 configure for configuration.
During configuration phase, the IR light would gradually get brighter, but not blink, only occasionally stay on completely, but still not blink.
Each step in manual mode also made it go brither, until it turned off again
