@LR I would recommend upgrading to the newly released SDK 1.4.1 from downloads.modalai.com
Simply, download, untar, and run ./install.sh
It'll retain any important calibration files and will re-configure the drone based off the SKU
@LR If you just want to change the camera that is streaming then modify /etc/modalai/voxl-streamer.conf to specify the desired camera. If you want to stream two or more cameras then you need to start a voxl-streamer instance for each one and specify a different port for each one. Then use voxl-mavcam-manager to inform QGC of the availability of the multiple streams. See https://docs.modalai.com/voxl-mavcam-manager/

Are you able to fly seeker indoor (for which no GPS available) with Position mode?
If not, for seeker to use VIO as position estimate you need to use this set of parameter for px4.
