@tom Yeah I am on 0.9 platform release

@modaltb Hey, thanks for the quick reply. Unfortunately, none of these work for us since it seems exposing one port prevents us from accessing another (I also can't find a ref to buy the M0130).

We found a workaround by having a USB hub on the m0125 instead of going over the native uart.

Also, if you are using very old SDK on VOXL2, the uart bridge may not be working 100% properly.

When in doubt, the best thing to do is to connect to the ESC using a serial to usb adapter going directly to a Linux PC (and run voxl-esc tools on the PC). do you have that available?

@ijones2 This is great news! It looks like everything is functioning as expected so no need to go through the unbricking process at this point.

It does appear that there is a fairly old SDK loaded on there so I would recommend flashing the latest SDK (1.3.3) from downloads.modalai.com under "VOXL 2 Platform Releases"

Just follow the instructions here to do so: https://docs.modalai.com/flash-system-image/#flashing-a-voxl-sdk-release

@Rowan-Dempster No problem! Kind of primitive but effective 🙂

Got it. Thanks.

@Jae-Park You should ship out the entire drone so that the team can verify that all of the components are functional, fix anything else that you may not have seen, and do a final flight test before sending back.

@tom Thank you. It works well

@JustinDev23 Great! Thanks for your patience, I just generated an official release of v0.16.2 to ensure that it makes it into our next SDK release.

@Cai-Bill Can you send a flight log of flying in manual mode and then trying to switch into position mode?

@Matthew-Wellner FYI

@milanerd The added capacitance helps VOXL 2 Mini's USB port achieve USB 3 speeds. We don't have that adapter to confirm a fix for your issue, but with the cable the link should transfer much faster

@Eric-Katzfey ok, Thanks, we tested GPS M10 and the problem solved.

@Alex-Kushleyev Hi Alex, When I hold the drone in hand and move around the room, I see that VIO is at 100%. It only fails when I shake the drone or start flying it. I'm not sure what's going wrong.

No @Matthew-Wellner , Our shipping dept is already done for the day and we missed UPS/FedEx drop-off times for next day delivery.

I can't offer anything other than consolation that we've had some of our customers be amenable to a demo with non-NDAA compliant stuff with our assurance we have a plan to switch over (especially yours since it is available and in-hand, but just not working at the moment).

I only wish I could probe your board remotely to help you figure this out... sorry.

@tahawaru Okay, that shows you have 1.14.0-2.0.78. If you want to build 1.14.0-2.0.63 then you need to check that version out instead.

@Alex-Kushleyev
Thank you for your reply.
I used MSU-M0026-1-01.
When changing to Green-ish, the gain becomes 69 (sorry, no snapshot).
I have a few other snapshots.

Hi Sergio. I'm handle a number of rover configurations here for the team. Reading thru the posts, let's take a step back to confirm your setup.

a. you are using the cube to output IMU data into voxl-cam.
b. you are using voxl-cam to output odom data [back] to the cube for (e.g. external vision localization)
c. the camera has been moved from the stock position of -45deg from horizon w.r.t. voxl-cam body to 0deg from horizon w.r.t. voxl cam body.
d. the cube is mounted w/IMU in standard orientation (0 deg to horizon/forward, aka imu RPY is 0,0,0)
e. you are not using a modalai flight core (option for voxl-cam purchase)

First of make sure your PX4 SENS_BOARD_ROT (or AHRS_ORIENTATION if Ardupilot) is set for a cube setup (I recall should be "No rotation" as well as from your photo). Please reply if that is all correct. If so, then we can move to the next step where I can show you how confirm vio's pose estimation (after that then we'll look at position accuracy).

@Moderator Thanks for the clarification, we will not expect a solution to this then.

@Alex-Gardner Thank you for your help 🙂
