@Eric-Katzfey Hi Eric thank you for the reply, we didn't exactly try using because of the mavlinks limitation in the working and handling of UDP connection as it sends data to localhost Port 14550 so all of the drones would be sending their data to 127.0.0.1 14550 port and this would create problem for handling multiple drone with same port.

Re: Unbricking a VOXL 2 - Pass but no ADB?

I'm unable to Unbrick voxl2, following the Unbricking guide https://docs.modalai.com/voxl2-unbricking/ I'm able to select the flatbuild and flash it but in the process of flashing the console on the web based ui shows Timed out and on the bottom it shows successfully flashed.

Upon switching the QDL back to off from normal the device doesn't reflect on the usb serial when running lsusb nor does it working with adb shell.

Re: voxl-mavlink-server GCS udp port

I’m currently working on a solution to connect a fleet of drones simultaneously to our home-grown Ground Control Station (GCS). Until now, we’ve been differentiating drones using unique IP and port combinations. However, this approach is not feasible with VOXL, as it transmits data to a fixed GCS IP and a hard-coded port via voxl-mavlink-server.

I came across a related topic where modifying the port was discussed. I’d like to know if there’s a supported method to configure or override the default port settings in voxl-mavlink-server, so we can enable multiple drone connections without conflict.

Any guidance or suggestions on this would be greatly appreciated.

Hello,

I’m currently encountering an issue with my VOXL 2 board. Until yesterday, it was functioning flawlessly, and we were actively using both the board and the integrated PX4 for our application.

However, following a routine reboot, the board became unresponsive and is no longer recognized as an ADB device. Running the lsusb command lists the board to be in QDL mode, which leads me to suspect potential file system corruption.

Before proceeding with the unbricking steps outlined in ModalAI’s documentation — which I’m cautious about due to a previous unsuccessful recovery attempt (here) — I’d like to understand what might have caused this issue.

Here are some relevant details about the setup:

• The board is powered via the VOXL ESC FPV 4-in-1 with Built-in Power Module (MDK-M0138-11-01).
• The ESC is powered by a 6S2P Li-ion battery, which is also connected to 5V and 12V BECs that supply power to other components.
• When powering the VOXL 2 board directly using the standalone power module (MDK-M0041-1-01), the board’s LEDs do turn on—similar to when powered via the ESC.
• Previously, the blue LED on the ESC would blink when powering the VOXL 2 board. After the issue occurred, the blue LED no longer turns on. Note that, the LEDs do start blinking when connected to another VOXL 2 board.

I’ve thoroughly inspected the setup and confirmed there are no shorts or obvious power issues. I would sincerely appreciate any insights into what might have caused this corruption and how to prevent it in the future.

Hello @Alex-Kushleyev @Eric-Katzfey

I am looking to control the servo via PX4.
Essentially, it will be a command either from the RC or GCS to open / close the servo motor.

But, if that is infeasible, I can make it work via an API on the CPU / Linux on VOXL 2 to be controlled via SSH.

Ashwin

Hello @Nathan-Raras ,

I apologize for missing your response.

I understand that it has been quite a while.
May I ask where can I locate the requested path?
'''
modal-qdl/qdl/qfil_app/src/data/qfil/cdt
'''

As I understand it, this path is present on VOXL, but I am not able to access VOXL at all.

Ashwin

Hello,

Can someone kindly respond to this query?

@tom Thanks for the quick response.
This board seems like a good option.

May I know the weight for this board, as the documentation just says X grams.

Hello,

I am currently exploring the development of an FPV system and would like to integrate a compact microphone for audio capture.

Could you please advise if there are any available ports on the VOXL 2 that would support this functionality? Additionally, I would appreciate any recommendations for miniature microphones that are compatible with the VOXL 2 platform.

Looking forward to your guidance.

Ashwin

Hello,

I am currently working on a project involving the VOXL 2 platform and would like to control a servo motor within my existing system architecture. Below is a summary of the current configuration:

• RC, GPS, and Magnetometer are connected to the J19 port.
• An FPV ESC is connected to the J18 port.
• The M0151 expansion board is connected to a Doodle Labs module.

I am considering two possible approaches for integrating servo motor control:

• Using the IO Expansion Board via a free UART Port on the M0151 Board
  I plan to connect the IO Expansion Board to an available UART port on the M0151. I would like to confirm whether this setup would support reliable servo motor control.

• Connecting the IO Expansion Board to J19 and connecting receiver to J2 terminal of IO Expansion Board

Could you please advise on the feasibility and potential limitations of both configurations? I would appreciate any insights or recommendations you may have.

Please feel free to reach out if any further clarification is needed.

Regards,
Ashwin
