ToF sensor

Chad Sweet

that all looks good. Will investigate further

gauravshukla914

Okay. Looking forward to your solution asap!

Chad Sweet

Can you please type and report the output?
opkg list-installed | grep royal

Chad Sweet

Assuming the ipk is installed, can you please then run this command and then try the ROS node again?

setprop persist.camera.modalai.tof 1

@Chad-Sweet

OK, good progress. That should be working. Can you give it a full power cycle and see if it says up?

gauravshukla914

I am not sure if I understood that. Can you please elaborate.

Chad Sweet

Unplug power from the VOXL and plug it back in. Then try the test over. You look like you're in a working state.

gauravshukla914

can you please explain this setprop persist.camera.modalai.tof 1

Chad Sweet

It is the way for software to tell which TOF driver should be used. Setting to 1 supports the HAL3 method you are using, setting to 0 supports the older libCamera method using tof_cam_ros

The HAL3 method is intended to give the developer more control over the pipeline

@Chad-Sweet
Thanks a lot its been a great help.

Hi @gauravshukla914 ,

Thanks for the help with this. We've released a new beta version of the voxl-hal3-tof-cam-ros that supports auto detection of ToF and defaults the persist.camera.modalai.tof setting properly.

It will be in out next voxl-suite release, but is available from our dev channel here if you are interested in using this link

The updated readme is here.

Thanks!
