I attempted to connect to the drone, but initially, the connection failed. After some time, I was able to establish the connection. While flying the Starling drone in offboard mode, it suddenly shut down mid-flight and fell to the ground. Following the incident, I was unable to connect to the drone using ADB or Wi-Fi for some time. What could be the reason for this, and what can I do to solve this issue?

@Shivam-Sehgal , are you able to ADB into VOXL2 and download the PX4 log from the flight?

Also, what SDK version were you using?

@Alex-Kushleyev , I am unable to ADB into VOXL2 today but I did download the flight controller log file after I was able to log in again that day from QGC.

https://review.px4.io/plot_app?log=81e3f3cc-1cf2-419a-8202-073a9dd46c3e  link to flight review for the log file. I don't remember  the sdk version.

@Alex-Kushleyev My Voxl SDK version is 1.1.2.

@Shivam-Sehgal , I have reviewed the log and unfortunately do not see any issues. The log terminates prematurely (before the crash), which may suggest that the PX4 process crashed (as opposed to a sensor issue or ESC issue, causing motor to stop, for example). But this is just a guess.

SDK 1.1.2 is quite old, we recommend using latest SDK if possible, since we always make improvements and fixes.

My recommendation is to get the vehicle back up and running and try to migrate to SDK 1.3.

@Alex-Kushleyev i can update the system but  I am unable to connect to voxl 2. How can I update the system?

## Reply by Alex Kushleyev (ModalAI staff) · 2024-08-26 21:35:57 UTC (in reply to Shivam Sehgal)

@Shivam-Sehgal , quick question.. So after the crash, were you able to connect to VOXL2 (how? ADB or wifi) to get the log from it? And now it no longer connects using ADB?

Here is unbricking procedure for VOX2 https://docs.modalai.com/voxl2-unbricking/, however that is typically done when a software update fails or the file system.

Can you please clarify whether you were able to use VOXL2 between the time after crash and now?

## Reply by Shivam Sehgal · 2024-08-30 23:35:59 UTC (in reply to Alex Kushleyev)

@Alex-Kushleyev Yes I was able to connect to drone both via wifi and adb that day, then next day I wasn't able to do so.

(Some Observation if it helps)
Also, I have 3 other starling drone in all of them there are four blue lights on the ESC that constantly flash.
In the one that does not connect there is no flashing.

## Reply by Shivam Sehgal · 2024-09-05 16:14:51 UTC (in reply to Alex Kushleyev)

@Alex-Kushleyev should I follow the unbricking process?

## Reply by Alex Kushleyev (ModalAI staff) · 2024-09-11 16:40:16 UTC (in reply to Shivam Sehgal)

@Shivam-Sehgal , Yes, you should try it, however i am not sure whether the recovery attempt will be successful. Typically unbricking is required when something goes wrong during SDK update or something like that, when the system is left in incomplete state. In your case, the drone was flying and stopped responding after a crash. The fact that it shut off during flight could mean there was a pre-existing issue (before the crash) which may be causing the board not to boot now. However, it is worth to try the unbricking and if does not work, please contact our RMA department, they will help you out.

@Alex-Kushleyev I did not unbrick it it had opened the voxl2 board and I was able to connect to it, then when I closed it it did not connect again. 
What I found out is when the hires and tracking camera are connected to the board I am unable to connect to the drone. What could be the reason for this?

## Reply by Alex Kushleyev (ModalAI staff) · 2024-10-22 21:20:11 UTC (in reply to Shivam Sehgal)

@Shivam-Sehgal , most likely one of the camera flex cables is broken and it is shorting one of the power rails to ground, which prevents voxl2 from booting. I suggest trying to connect one camera at a time to narrow down the issue to a specific camera and then inspect the “bad” camera’s flex cable or extension flex cable.

## Reply by Shivam Sehgal · 2024-10-22 22:07:38 UTC (in reply to Alex Kushleyev)

@Alex-Kushleyev I connected both cameras to the other connector on which tof sensor was connected. I could connect to the board. Also the tof sensor worked on the other board.

But I could not connect to the tracking and hires camera, I could only connected to TOF sensor.

@Shivam-Sehgal I connected the cameras back in their basic configration that it is shipped with.

Then I ran voxl-camera-cameras and set it to 06 - D0005 Starling pmd-tof imx214 hires ov7251 tracking.
```

@Shivam-Sehgal , sorry, can we please take one step back and clarify something..

Does the VOXL2 board now boot with all the cameras plugged into the original configuration?

Also, when you say `After this I manually restarted the voxl-camera-server and the connection broke after the output below.` -- which connection are you referring to?

If you are able to connect all cameras to their original slots, but something is still not working, i suggest that you test with only one camera enabled at a time and figure out if there is still one camera that is not working.

Alex

@Alex-Kushleyev  I hope this clears somethings out, its confusing for me too. 

 no it does not boot now with all the camera's plugged in original physical connections.
It was not about the physical connections, but when the camera service started then the connection broke.

First I shifted the physical connections of the camera's as mentioned above, after which I could boot but the hires and tracking camera did not work or start. (https://forum.modalai.com/post/19383)

Then restored the original physical connnections, set the voxl-configure-camera to it original configuration it's shipped with and then restarted the voxl-camera-server. 

When I started the service this the output of it, after this output the adb and ssh connection broke and I was unable to connection to the voxl2 board.

@Alex-Kushleyev I was able to point out maybe it's the hires camera that's the issue. I don't know why but I was singly able to run all other camera's but not the hires camera. 

What defect should I look for?

Also, while doing all that I broke the tracking camera's connector and the 2 in 1 camera boards. I will be ordering those. How can I remove the 2 in 1 camera board from the voxl2 board?

@Shivam-Sehgal , sorry for the delay!

Can you please contact our RMA department and send them the pictures of the current state of the board and camera adapter interposers. Our production team can evaluate the pictures. On some products the interposer boards may be glued in place for robustness, so they can suggest best way to handle it.

In general, here is a diagram from the Hirose's product manual that shows how typically you should remove these connnectors:

@Alex-Kushleyev It's a form to send my drone for repair, can't I repair it myself? I have already ordered all the parts required. I just need to understand how to remove the glue.

@Shivam-Sehgal I will see if a member from our production team can chime in here

@Shivam-Sehgal 
The glue is an easy to remove RTV silicone adhesive. If you follow the instructions posted by Alex, you should be successful. I've done this myself a couple of times.

After removing you will need to clean away as much of the remaining glue on the voxl2 as possible before installing the new adapter board. You don't necessarily need to apply glue when installing the new board, but we find it helps with keeping the adapter from accidentally teetering at the hirose connector.

Please let me know if you need further help with this matter

## Reply by Shivam Sehgal · 2024-12-18 14:46:59 UTC (in reply to Jeremy Schmidt)

@Jeremy-Schmidt So I don't need heat or any special tool for it I can directly remove by hand?

## Reply by Shivam Sehgal · 2024-12-18 17:25:32 UTC (in reply to Shivam Sehgal)

@tom  I was able to get the camera board out thank you but ...

When I again add the 2 new camera boards with out the camera's attached it works I can adb into the board, but as soon as any camera is added I cannot adb into the board.

I am using 2 new boards and 2 new camera's tracking and hires it seems like the issue is something else what can I do?

## Reply by tom (ModalAI staff) · 2024-12-18 21:16:08 UTC (in reply to Shivam Sehgal)

@Shivam-Sehgal Double check the pinouts to ensure the sensors aren't being plugged in backwards, that is the most likely cause of a board not booting

## Reply by Shivam Sehgal · 2024-12-18 22:15:02 UTC (in reply to tom)

@tom thanks I had opened the board so I did not notice it, only if I had assemble I would have noticed it.
Thank you so much it worked!

## Reply by Shivam Sehgal · 2024-12-23 21:55:16 UTC (in reply to Shivam Sehgal)

@tom @Alex-Kushleyev 
I corrected everything and it seemed to work for a minute there then again adb connection broke.

I disconnect the cameras and I am able to adb but with the cameras it does work for like 10 seconds and then the connection breaks.

## Reply by Alex Kushleyev (ModalAI staff) · 2024-12-24 22:44:37 UTC (in reply to Shivam Sehgal)

@Shivam-Sehgal , does it look like the board is rebooting after 10 seconds of running with cameras enabled? also, what if you ssh into the board, does the SSH connection stay alive when the cameras are connecting?

Also, how are you powering the drone for this test - battery or power supply?

Alex
