Optical flow sensor data not available in topics published - only topic name exists

PX4 Autopilot
1

After doing some research realized that dds_topics.yaml plays a role and in default dds_topics.yaml optical flow sensor topic is only under subscriptions and not publication.

As we are directly flashing our px4 with the pre-built PX4 firmware binary from Releases · PX4/PX4-Autopilot · GitHub , for example ark_pi6x_default.px4 we are unable to change dds_topics.yaml as we need.

In my understanding .yaml is a configuration file used also to change values for a binary instead of rebuilding when intending to just change some configuration values.

Is there a way to update dds_topics.yaml when using pre-built binaries?

I don’t think so. See the generate_dds_topics.py file. @Benja any idea how we could do this via a file on the SD card? That would be a nice feature.
