Hi,

Thank you for this software. The emitter does not work even after successful configuration. You'll find below the requested output.

If you execute linux-enable-ir-emitter run after the boot, does the emitter work ?

[Johannbr]

Hi, thanks for the reply.

I just did: sudo linux-enable-ir-emitter boot enable Output INFO: The boot service have been enabled.

And linux-enable-ir-emitter run with no output

Then, sudo howdy test => camera is working but the IR emitter does not work.

[EmixamPP]

Is howdy using the /dev/video2 camera ?

[Johannbr]

The device_path used by howdy is: device_path = /dev/v4l/by-path/pci-0000:06:00.0-usb-0:2:1.0-video-index0 which is: /dev/video0

[EmixamPP]

Please change the variable and use /dev/video2. In fact there is no issue :) /dev/video0 is your regular camera

[Johannbr]

Indeed, the emitter is on now. Thanks for your time.
