@James-Strawson Quick update. I was able to lower the value to 300 and it seems to work as well.

I have been starting to integrate a companion computer/external flight controller to the VOXL2. Documentation says the preferred method would be to use the USB 3.0 Expansion Board (MDK-M0151-1-00). I have already placed an order for one of these. While waiting for this to come in I am trying to use (M0078), which I already have in my lab. I see in the datasheet for M0078 that J5 is a UART port that is not populated. If I populate the connector would I be able to use this for communication with a external flight controller?

@tom I was able to try another power module and cable I had here. I still received the same results.

@pthomason I am using USB-C to USB-A on my host machine.

@tom No. I do not see a change in lsusb when the Voxl is connected via USB-C.

I have a QRB5165 VOXL2 running SDK 1.1.2 that will not allow me to connect to it through ADB. This VOXL2 has been operational for some time now until we were unable to connect over ADB.

All cameras, add on boards, etc have been removed from the VOXL2 and I only have the power connection and USB-C hooked up. I have tried to go through the unbricking process, however once I initiate the flash using qdl I receive "Waiting for EDL Device". I have made sure the SW2 is in the on position and made sure to follow the unbricking procedure here ( https://docs.modalai.com/voxl2-unbricking/). I have tried multiple USB-C cables and multiple Host Machines running Ubuntu 20.04 and 22.04 (Not VM).

Are there any suggestions or tips to help me solve this issue.

@tom I checked wire harness going from the VOXL 2 to the Doodle Labs. Everything seems in check there. Haven't noticed anything wrong with the connector or solder joints on the pcb located on top of the Doodle Labs. Would you recommend getting a RMA going for this radio?

@tom I am not able to ping the Doodle Labs Radio from the VOXL2 that is connected to it.

I received a Doodle Labs Radio in my last shipment that I believe to have an issue. After programming the VOXL2 I am unable to get connection over QGC. I have multiple VOXL2 and Doodle Labs set up in house that I have been able to use to help troubleshoot this issue.

The Doodle Labs Radio that is in question is in the air vehicle. I am able to ping the IP of the Air radio from my Laptop which is connected to a Doodle Labs radio. I am also able to pull up the Web interface for the Air Radio as well. I am not able to ping the VOXL2 or open VOXL Portal. I have tried to reset the radio to factory defaults and also flash a backup file from a known working radio with no luck. I was also able to test out different harnesses and even plugged the Radio in question to a known working VOXL2 setup with the same issue. I was able to plug the VOXL2 that is in the same vehicle with the questionable Doodle Labs radio to another Doodle Labs Radio and it linked up to QGC with no Issues.

With my troubleshooting it seems I have narrowed it down to this Doodle Labs Radio. I am not sure how to continue troubleshooting the issue. I guess it could be something wrong with the actual hardware of the radio.

Any information to help me solve this issue will be appreciated. Thanks!

@Alex-Kushleyev Are you saying run this in the Mavlink Console in QGC? If so I receive "command not found"

@Eric-Katzfey I am waiting for a order from you all now that will allow me to test with the ESC. Once I get that in I will be able to connect it to the cube and see if it works.

I was able to load the mainline PX4 on a cube I have here. I looked in the parameters and did not see any of the VOXL_ESC_xxxx parameters listed. Is this something that should only appear when the VOXL ESC is connected?

I currently have a VOXL2 running SDK 1.1 with a VOXL ESC (MDK-M0134-6-01). I am looking to add a Cube running PX4 instead of having PX4 running on the VOXL2. What would be the best way to accomplish this? Am I able to run the latest dev version of PX4 1.15 or would I need to run the VOXL Branch of PX4 to be able to talk to the ESC?
