    @JB1 Our voxl-remote-id software with WiFi dongle is intended only for reference and is not meant to be a commercially ready system for our customers who need a remote id solution for their VOXL2 based drone products. Integration, testing, validation, and FAA registration with desired hardware is up to the end user. At a minimum the manufacturer id would need to be changed from ModalAI's id to your companies issued manufacturer id.

    We are using the VOXL2 Mini with the M0041-4 power module on a 6S drone. I had been testing it on the bench with a 24V power supply without issue for the last few weeks. I was moving it onto the drone which is 6S and soldered power wires directly onto the ESC battery pads and added and XT30 to connect to the power module. When I plugged in the power module it sparked and I quickly unplugged. I have double checked polarity after the fact and it is correct. I put a multimeter on the xt30 and measured 25.1V. I do not see what I did wrong to make it fry. The IC that blew is the actual voltage regulator (marked 327;LGHW;8937 on the IC). Unfortunately I tried powering the VOXL2 mini up with another M0041-4 and my power supply and that is dead too. What am I doing wrong? Let me know if there is more information you need.

    @RoyAzriel I'm guessing that there is a version mismatch somewhere. Can you install a recent SDK from scratch and see if everything comes up fine? And when you say "dev crone" do you mean that this is a custom drone and not one of our products?

    @Eyal ,

    I will look for an indoor flight log from a stinger. At hover, the power usage should be around 110-115W based on motor dyno tests. The peak motor current can go up to 300W (per motor), but it's not possible to have all 4 motors maxed out.

    Regarding ethernet.. It is actually possible to establish a full wired interface using the same usb interface that is used for ADB. it is a lot more efficient that using something like adb port forwarding. We have some scripts that set up the full network with NAT, when voxl2 / voxl2 mini is connected to a linux host. There is one script that enables the usb ethernet in voxl2 kernel and then there is the host side script to set up the networking and tcp/ip rules for NAT (so that voxl2 can access internet via the host) -- the NAT part is actually optional.

    Actually the first part (without NAT) is already documented here, you could try it : https://docs.modalai.com/qgc-via-adb/ -- this will give you a full tcp/ip connection to the linux host.

    For downloading log files, we get about 35-37MB/s, it seems to be a 400Mbps link. Even with 1Gbps usb3 adapters we don't get full 1Gbps, so this may be the best you can get. Can you clarify your application for the network connection?
