ToF sensor

[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!
