    @Zarrar The Starling 2 meets all of those specifications. The obstacle avoidance and gps-denied navigation are tuned to indoor environments

    @modaltb thanks for the follow up. I'll see if I can secure a starling 2 soon.

    @boga , Can you please double check the following: amount of free space in the /data partition: df | grep data check the write speed to the data partition : dd if=/dev/urandom of=/data/test.bin bs=1M count=1024 (this will write a test file of size 1GB). For example, using voxl2 i result i got was (on VOXL1 it will be a bit slower): #set cpu mode to perf voxl-set-cpu-mode perf #perform the write test using randomly generated data (may be limited by speed of /dev/urandom) voxl2:/data$ dd if=/dev/urandom of=/data/test.bin bs=1M count=1024 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 2.85171 s, 377 MB/s (you can / should remove /data/test.bin after the test to free up the space) Alex

    @Eric-Katzfey said in Regarding controlling drone flight using code: @cy208183395 I would take a look at the documentation for MAVSDK. It has a python interface available and can do drone control. Thanks for your reply

    @Jetson-Nano In SDK 1.2.0 we did start pushing the default config of voxl-mapper a big harder with smaller voxl sizes, longer ray lengths, and double the UI update rate to better complement the newer TOF sensors on the Starling 2. Part of this update was also to lock some of the heavier parts of the mapper processing to cores 4,5,6 to make sure VIO wasn't affected too much. However, if you are still seeing a difference in VIO performance between mapper being on and off then there may still be some optimization to be done. Just to confirm you are seeing worse VIO performance when mapper is enabled, correct? If so, please try increasing the voxl_size parameter in /etc/modalai/voxl-mapper.conf from the default 0.1 to 0.25, and set the cpu into performance mode on bootup by changing the normal_cpu_mode field to "performance" in /etc/modalai/voxl-cpu-monitor.conf. The map will be very course and ugly with such a big voxel size but I'm just curious if the power cpu use helps resolve the issue. For reference, here is the commit history for voxl-mapper showing the recent tweaks for SDK 1.2 and newer that turn up some of the knobs.

    @Judoor-0 Yep exactly, if the drone is already in fastboot before running the flashing script it can't identify which board it is (M0054-1, M0054-2, M0104-1) so it has to give you all options. This time since it has ADB access it can be smarter and just ask you the possible options it knows are supported for your hardware

    HI @Jeffrey-Mao Another consideration for baro is active airflow. We typically provide a "cap" on our baros in our drones or flight-decks to ensure it is not exposed to sunlight (as Eric stated) but also active airflow which can show up like air pressure noise. Our 3D models repository has a 3D file of this cap, in this case for FlightCore to give you an example: https://storage.googleapis.com/modalai_public/modal_drawings/Flight_Core_Barometer_Cap.STEP Hope this helps.

    The Flir Lepton feature is still in development. Please check future release notes in VOXL SDK for updates on availability.
