@wilkinsaf Yup, this guy: https://www.modalai.com/products/voxl-lte?variant=39300535681075

@Aaky I sent you a link in email

@Eric-Katzfey Oh, ha. I could have sworn it wasn't outputting my custom module status message. Checking again I see it though. That's silly.

duplicate perhaps, see https://forum.modalai.com/topic/2313/no-gps-lock-for-vehicle

It is because port 53 is already in use

@tom said in Sentinel VOXL2 Ubuntu Upgrade:

@Adeeb-Abbas We haven't implemented ros2 ourselves yet so I can't give a definitive answer, however it's on our list

Oh interesting. The marketing material repeatedly said "ROS / ROS 2" so I just assumed there's some level of ROS2 support.

https://www.modalai.com/products/sentinel-development-drone?variant=40446488805427

says the following -
Software Features
PX4, ROS 1 / 2, Ubuntu 18.04, Open CV, MAVROS, MAVSDK
Open Source Linux kernel, cross-compilers
Docker build environment for CPU, GPU (OpenCL) and DSP (Hexagon SDK) heterogeneous computer vision and deep learning processing

@Veldrovive No, 1.11 is not supported and it would likely be a lot of effort to make it work.

Thanks @Aidan-Dempster, that worked.

@Aidan-Dempster I will send you an email.

@Chad-Sweet Thanks for reply,
I am just triggering via python subprocess

voxl-send-command hires_snapshot snapshot

able to get snapshots.

will try to look into mavsdk also.

@Chad-Sweet Thank you for getting back to me.

The radio we are leaning to use has an SPI interface. However, I am not opposed to switching radios if there is an easier to use I/O on the VOXL.

We are leaning to using Adafruit RFM95W based on the SX1276 LoRa® module with SPI interface.

@tom Yes, thanks! That is a good idea. I will do that.
I was looking at the release page of the system image and saw this line with 1.5.3 internal release:

HLOS Added service file that changes SLPI restart level to avoid board crash when SLPI crashes

What is SLPI and could you describe a little bit more what kind of issues you saw when SLPI crashed?
I also sometimes saw px4io io_reg_get(4,0,15): data error -5 in the logging so maybe that could be related?

@afdrus the relocalization is external to the VIO EKF. You can trace this code path here: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-vision-hub/-/blob/master/src/tag_manager.c#L110

@I_Dwyer I have been down the rabbit hole here. It seems that qualcomm has not used any of the standard network management tools like Netplan. They use a hybrid of Systemd-Networkd and a wide range of complex scripts to manage all the interfaces. None of the scripts are standard. I am at the point of possibly stripping all of that out, and replacing it with either Ifupdown or Netplan and creating a firmware build that works better for our use case. There are a number of problems with the older Qualcomm network scripts, such as the DHCP management you are encountering. For example I have noticed that if WWAN0 has an IP, then WLAN0 will NOT get an IP from the DHCP server, even thought the wifi is connected to the local AP! To get around that I added an ifconfig statement issuing a static IP to wlan0 every time the drone boots, but this is a hacky solution.

Would like to see ModalAI replace the entire Network Management stack with something better and easier to maintain.

@황인호 It isn't required to use voxl-modem to interact with the modems if you'd like to do a custom config.

In your case, I'd recommend using voxl-configure-modem with the quectel option to handle Quectel bringup and then creating a custom script / service file (or modifying the existing one) to handle doodle bringup.

Although doodle bringup is very basic, if you follow the code path here in the startup script: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-modem/-/blob/master/scripts/voxl-modem-start#L99

it monitors the eth0 network interface and if the IP address isn't what is specified in the config file then it assigns said IP address. This could be broken out into a different script

@Chad-Sweet - I have the same issue. How to enable the 4K resolution for IMX412 that we bought for $349 USD from you?
