VOXL 2 Mini falls under VOXL 2 as the core components are the same.
Hope this helps you.
Thanks!

Thanks for the very detailed write-up and troubleshooting. There is a lot of useful information here, and this is a tough challenge. I hope we can help get it resolved with you.
The first thing that stands out to us is the custom extended-length USB harness between the Doodle Labs radio and VOXL 2 Mini. Before digging further into software, ESC firmware, or platform parameters, I would focus on that physical USB connection.
USB 2.0 High Speed is sensitive to cable construction and signal integrity. Extending the MCBL-00080 interface using discrete, untwisted, unshielded JST-GH conductors is not equivalent to extending it with a properly constructed USB cable. The added length also increases susceptibility to both radiated and common-mode noise, particularly in an electrically noisy environment such as a high-current multirotor.
We should also acknowledge that our standard development cables are not necessarily optimized for the highest-noise or final-production UAS environments. They are primarily intended to help get systems connected and operating during development. For final aircraft integrations, we generally encourage additional cable optimization where appropriate, including shielding, ruggedization, strain relief, and dedicated cable routing or cable channels that keep sensitive interfaces away from high-current and high-noise paths.
We have seen USB stability issues on aircraft when cabling and routing are not ideal, especially around ESCs, motors, and high-current battery wiring. The fact that your disconnects correlate strongly with motor current transients rather than steady-state current makes the custom USB harness and associated grounding/noise coupling particularly worth investigating.
I would recommend addressing the USB harness first:
Keep D+ and D- as a tightly coupled twisted pair and keep the run as short as practical.
Use a shielded USB-rated cable rather than individual discrete wires for the extended portion.
Adding shielding is absolutely a good approach here. Ideally, use the cable shield as a shield rather than simply adding another signal-ground conductor.
Keep the USB harness physically separated from ESC phase wiring, battery leads, and other high dI/dt paths.
Your plan to improve the ground path and experiment with ferrites is also reasonable, although I would first correct the basic USB cable construction before trying to solve the problem primarily with ferrites.
I would not assume there is a specific maximum J3 cable length where it suddenly becomes unreliable. Cable construction, impedance, routing, grounding, and the surrounding EMI environment all matter. A longer run made from discrete untwisted/unshielded conductors is certainly more susceptible than the stock harness, and yes, it could plausibly produce the transient-induced disconnect behavior you are seeing.
Moving the ESC bulk capacitor to the recommended location is also important, particularly on 6S, and I would still make that change. The improvement you observed when powering VOXL from a bench supply is another useful indication that conducted or common-mode noise may be contributing. There may be more than one coupling path here.
However, given the custom extended USB cable construction, I would correct that first and repeat your 0 -&gt; 65% actuator transient test. That is actually a very good controlled reproduction test.

2d Lidar 50gram above the gps bridge
2 x light ilumination (front, down - we are flying and dark tunnels next to tracking cameras)
props guards the are seen by the tracking camera
we have added tof camera, moving from C28 to C29 ( currently its not working or wired in sw), we have changed the extrinsix.conf file in /etc/modalai accordingly.
all of those changes did not effect our filght and we had good flight with good vio during the flight

If the platform we are discussing has this added elements, it is a custom frame.

@RoyAzriel said:
we are exploting a tunnel for the first time.we use the poshold durung junction turns to hold in place during turbolance. my answer would be we can live with resets assuming we can accumulate the positions for mapping between the resets.

Yes, so that is a mapping/loop closure software responsibility, not VIO.

@RoyAzriel said:
how do we make sure what you are saying is right and we are passing estimates to px4 ?

Check your voxl-vision-hub.conf, if en_vio is set to true, it passes to PX4 as external vision estimates. Also rectified by:

@RoyAzriel said:
HGT_REF=3 //VIO
EKF2_EV_QMIN=16
EKF2_EV_CTRL=15

For now, our PX4 flavour doesn't handle VIO resets gracefully always. We currently have overcome this issue by using VFC. Hence, the reason I suggested that you should try to repeat the same maneuver under VFC position. If you have any questions on how to enable VFC, please feel free to ask.

@RoyAzriel said:
what should I expect ?

Likely more robust performance under resets at the potential cost of manually hover thrust, PID/PD tuning.
PS: I wanted to try reproducing your setup here with non-modded Starling2 Max, but I am unable to match your setup without logs

rfd900x

Hi @Raiyan-Alam,
My suggestion: keep the Wi-Fi adapter on USB and feed the RFD900X separately.
You can pull an extra 5V feed using this power module cable, which splices off a 5V red JST SFHR connector:
https://docs.modalai.com/cable-datasheets/#mcbl-00095
Splice from that into the RFD900X's 5V input. For the M0151, don't power the RFD900X off USB but pull it directly from the power module supplying VOXL 2 instead.

That is indeed a cap. It is a 4.7uF 25V 0603 in support of the 5V input rail when sourced by J5.
[image: 1782190949170-0a20b27c-498c-4971-be16-f9c02719c08f-image.png]
We have so much margin on the 5V power rail, I would not worry about one cap missing. My best advice is to clean up that area to make sure there is no FOD or ripped up pads that can cause a short on that 5V rail from the broken cap, and just keep developing.
Let us know if you have any other issues.
Thanks!
