@tom
P.S. I am currently working with the Drone Sentinel VOXL 2 and the drone is connected via LTE but without Wi-Fi, because there is no wifi dongle.

@tom
The issue still persists for me. Do you think my setup could be causing the problem? I have an M1 Mac processor, and I'm using a virtual machine with UTM(Visualizer). Could that be causing any limitations? Should I try a different setup, and do you have any recommendations?

@tom

I think I need a wifi dongle for it and I haven’t tried it with wifi.

@tom
No, I’m not able to pull up the stream in VLC, I’m getting this error:

@tom

No worries, I reverted the voxl-streamer configuration to its original settings, restarted it, then updated and restarted voxl-mavcam-manager.conf.

Afterwards, I attempted to set the RTSP stream to the specific IP address:

When I checked voxl-streamer, the output showed the following:

This is the errors that I got from Qground:

@Zachary-Lowell-0 @tom

I have configured Tailscale as a priority network:

While setting up the voxl-streamer (located at /etc/modalai/voxl-streamer.conf) with the new URL, I noticed that the parameters auto_ip and url were missing:

I have added both parameters, setting auto_ip to false and updating the url with the Tailscale IP address and I checked the voxl-streamer and found that the stream value is still showing as 127.0.0.1:

After these adjustments and power cycling the device, Additionally, I attempted to check the connection in QGroundControl and VLC, but I'm encountering some errors:

@tom @groupo

The setup is working well. I successfully pinged both the VOXL drone and the parent computer:

Additionally, I managed to stream using MVP, and it functioned:

As for the wwan0, I have confirmed that an IP address is displayed:

Both voxl-streamer and voxl-camera-server is enabled and running:

However, I'm still encountering some difficulties with streaming on VLC and QGroundControl (QGC). I've installed the necessary GStreamer dependencies, but I continue to receive errors when attempting to stream on both platforms.

I have following the instructions in this link to install gstreamer properly:
https://gstreamer.freedesktop.org/documentation/installing/on-linux.html?gi-language=c

P.S: I'm using Ubuntu 22.04.5 LTS

I have connected QGroundControl (QGC) to my VOXL 2 using a 5G modem and Tailscale VPN. However, I am unable to stream the camera feeds.

Additionally, I tried using VLC, but I’m not receiving the video stream. Here are the error messages I am encountering in both QGC and VLC:

@tom It worked! I tightened the screws, and it turns out it was a hardware issue. I've installed the Tailscale VPN on both the drone and my machine, and I've completed the calibration and binding. However, I'm having trouble starting the camera; it's not turning on in VLC or QGroundControl.

@tom

I have double-checked that the 5G add-on board is fully seated, and I followed the same process that worked successfully before the update. Given the current issue, what would you recommend I check next to help resolve this? I have attached a screenshot where I tried to reconfigured the modem and the issue still persists.

@tom
This is what I got when I tried ifconfig there is no wwan0 in the list

@tom I'm having trouble pinging the drone. I've set it up using a 5G modem (since the drone that I have doesnt have a wifi dongle) [VOXL AL & 5G Development drone-sentinel 5G LTE Modem] to connect to QGroundControl and proceed with installing the VPN on the drone. However, when I attempt to ping google.com, I get an error stating "unknown server," and I'm unable to see the drone's IP address. Prior to updating the SDK, I had successfully configured the modem and connected to QGroundControl via Tailscale VPN and I don't know why I'm getting these issues now. Any assistance in resolving this issue would be appreciated.

@tom

It worked! I have attached a screenshot of the update:

@tom
Hello,

I followed your instructions and ran sudo dmesg -wH to monitor the kernel messages while reproducing the issue. I observed the output, which I’ve attached as a screenshot.

For context, I am running Ubuntu on a virtual machine (VM) and not directly on my hardware. I attempted the first flight of the drone, (VPN Tailscale) and while everything else was running smoothly, the only issue I faced was that the cameras did not turn on.

@tom Yes the permissions are there, I have attached a screenshot of the permissions. In the previous post sceenshot it shows as "[INFO} Found fastboot device", but once I send 1 and enter it's stuck.

@tom said in issue with starting the cameras on my VOXL 2 device.:

@Rawdha-R I think the best first step would be to load the latest SDK on your VOXL 2 as that SDK is a few years old at this point.

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

I tried flashing the latest SDK (1.3.3) from downloads modalai under VOXL 2 platform release[link text] It is stuck at this point, please see the screenshot above.

@tom this is the output: Vol version: --------------------------------------------------------------------------------

I am experiencing issues with my VOXL 2 device. Specifically, the voxl-inspect-sku command is not found on my system. Additionally, I am encountering problems with the ModalAI repository configuration which might affect package installations.

Here are the details:

• The command voxl-inspect-sku is missing, and I am unable to locate or install it.
• The repository configuration is as follows:
