    Screenshot from 2024-07-31 13-50-14.png Hi, running a VOXL 2 with voxl-px4 firmware version 1.14.0dev, as seen in the attached screenshot in QGC. I believe we had to use this version (or a very similar 1.13 version) because other versions did not support our octocopter layout. Multiple sources of documentation say I should be able to enable the lidar-lite drivers by changing the aforementioned parameter, or at least detect the existence of the lidar as an i2c device by running i2cdetect in the mavlink console. I am not able to find any relevant parameters, like SENS_EN_LL40LS, or run any diagnostic commands to view the i2c buses. Does this version of the firmware not contain the necessary drivers / parameters in order to connect external i2c devices? And, if so, is there a firmware version that meets both our needs (i.e. has the drivers / parameters & also supports octocopter layout)

    Thanks, sorry for the confusing question!

      @jonathankampia We only add drivers to the build that we have used and tested with. The ll40ls driver is not one of them so you would have to add that to the build yourself.
