    Mavlink messages for setting flight mode use the MAVLINK_MSG_ID_SET_MODE message type (same as APM). Modes are defined in the uOrb layer under the vehicle_status.msg fie, which C headers are auto-generated at build time. The auto-generated file is under the build directory as vehicle_status.h via the NAVIGATION_STATE_* variables. And example of using modes in runtime code are in the mavlink_messages.cpp file (search for vehicle_status_s::NAVIGATION_STATE_AUTO_MISSION) and modes are processed in the Commander.cpp file. Both files under the src/modules directory of PX4.

    @Eric-Katzfey Thank you for your help. I followed your steps and it worked immediately. I am now also able to generate the ipk-package and push it to the VOXL. When I use adb shell, the file appears in home/root/ipk. I tried a few things, but I still have some questions: How can I run the i2c related files from "libapq8096-io/lib/python" on the VOXL, for example voxl_i2c_scan.py? Can I also make my own python scripts and run them?

    @Daniel-Lin ModalAI does not have any plans to produce hardware emulation at this point. However, I don't think buggy code will ruin an m500 (assuming you aren't flying, of course). We develop all of our hardware device drivers directly on target without any issue. For added safety, please remove the propellers before doing any such development.

    @Remco-Roelofs You can find more information about our Microhard and Doodle Labs support here: https://docs.modalai.com/microhard-modems/ and here: https://www.modalai.com/collections/accessories/products/voxl-microhard-modem-usb-hub. I would urge you to work with Microhard and Doodle Labs directly to verify that their products can do what you need.

    @tom After playing around with CP_DIST, it seems any value > 0 causes position mode to no longer want to allow x/y translation. From what I understand, any value < 0 disables object avoidance. Is this true? As far as I'm aware, my settings should be in parity with Modal provided guidance in regards to seeker setup with additional configurations overridden to support voxl-mapper. Thanks for the stabilized advice @mohammednaveed, I've gone as far to replace manual mode with this setting.

    @Todd-Humphreys Hi Todd, I believe they are replacing them with almost identical motors but with a slightly higher KV value. If you can source those then they would be a drop in replacement. If you're interested in something else, then here's some that I've tested before. The only thing is you'd need to solder the 3 male 2mm bullet connectors onto each motor. Otherwise they're drop in replacements. https://usa.banggood.com/Racerstar-Racing-Edition-2216-BR2216-810KV-2-4S-Brushless-Motor-For-350-380-400-450-RC-Drone-FPV-Racing-p-1083206.html?utm_source=googleshopping&utm_medium=cpc_organic&gmcCountry=US&utm_content=minha&utm_campaign=minha-usg-pc&currency=USD&cur_warehouse=CN&createTmp=1&ID=521309&utm_source=googleshopping&utm_medium=cpc_bgcs&utm_content=sandra&utm_campaign=sandra-SSC-usg-sku-1019-xp-cvrcart-11sale-21&ad_id=554267045258&gclid=CjwKCAiAjoeRBhAJEiwAYY3nDF7t6brTndAN6m0qocX3YTDihgCK1dw6y2-u2YtW9OWuC_Xq_bipZxoCnv8QAvD_BwE

    voxl-cross 1.7 is a build containing some new gcc toolchains for projects that are not yet on stable. The cross image is meant to be able to be easily built by any user, hence why it was built and installed when you installed the docker image. We've just pushed that image to the downloads page should you need to download it from there. As for the docker image docs, you are correct they are out of date right now, we're planning to update them soon and have been delaying doing so because we've been making changes to them.

    If you've made specific changes to specific config file you'll need to back them up manually either to a host pc or the data partition, otherwise the data partition will be saved which contains the camera calibration files and the factory settings for the config files which can be restored on a new system with voxl-configure-mpa --factory-reset

    @modaltb All right, I see. It does sound tough. Instead, I think I may have a chance to only enable the stabilization by manually pre-set a fixed angle for the gimbal. If so, I don't need to connect to VOXL-flight, and I could just need to think about a separate power supply for the gimbal, right?

    @Chad-Sweet Thanks, I see. I had the debug board, but it may not be able to work for special expansion. Anyways, I will think about that.

    ModalAI does not produce fixed wing aircraft, but it is possible to use our technology for fixed wing aircraft. We do not have any documentation or direct references as of now though.
