Package installs without internet

[Chad Sweet]

The easiest would be to use an add-on board that provides connectivity either directly or with a WiFi dongle. The supported Wifi dongles list can be found here: https://beta-docs.modalai.com/voxl2-wifidongle-user-guide/

@sarahl Some packages in dev-deb will work on RB5 as well as Voxl2, but they are really only intended for Voxl2 at this point. We will be making a formal release with a set of packages that work on both RB5 and Voxl2 in about a week.

[sarahl]

@Eric-Katzfey Thanks Eric, I look forward to the release! Any update on when that will be?

@Chad-Sweet I finally got a hold of a wifi dongle from the lab, but it's this one so I'm not sure if it's compatible. So far, it's not lighting up as usual when plugged into the fastboot board (M0078) via the usb-female connector. This dongle usually works with our other ubuntu machines, but maybe we'll have to order some of the supported ones listed on the page. One thing I wanted to ask about that docs page, it mentions under the "rebooting" section that the dongle should now be connected to voxl2 via usb-c. is that typo? I have it connected via the fastboot board and jst-to-usb cable, but the usb-c is being used for adb currently. Also, is there any indicator on the expander board that it's properly plugged into the voxl2?

[Eric Katzfey]

@sarahl No, it definitely does not need to be in USB C.

@sarahl The dongle's driver is most likely not built in to the kernel by default. What does lsusb show? It may show the name of the necessary driver.

[sarahl]

@tom this is what lsusb shows:
Bus 001 Device 003: ID 7392:b811 Edimax Technology Co., Ltd

[sarahl]

Separate question: so I have wifi hooked up on an RB5, but everytime I reboot, the ip address changes. Is there a way to change that? It doesn't seem to happen with my voxls (in station).

[tom]

@sarahl You'd probably be better off purchasing one of the dongles listed here: https://beta-docs.modalai.com/voxl2-wifidongle-user-guide/

It takes some work to integrate a new WiFi driver and isn't the most straight-forward thing to do.

@sarahl As for static ip on RB5, I would check out this thread for more info: https://forum.modalai.com/topic/794/how-to-set-up-a-static-ip-in-rb5/17?_=1649955285381

[tom]

@sarahl It is a known bug with the Thundercomm SOMs.

[sarahl]

@tom thanks! we did put in an order for some, so hopefully I will get those soon. also thanks for the link, I'll check it out!

So I'm trying to reflash the Voxl2, but the image listed in the docs (https://docs.modalai.com/voxl2-platform-release/#voxl2_platform_121-07) doesn't seem to be available on the downloads page, just 1.1.4. Is this available yet?

We've had issues installing the available system image (1.1.4) with/without the fastboot board, either with fastboot devices showing nothing, or getting an error like:

Edit: Actually, I got the fastboot image flashing to work on one board! But still wondering if this updated image is available, thanks!

[A Former User]

We just uploaded the image to the downloads page, it can be found under the VOXL2 platform releases folder!

[sarahl]

@Alex-Gardner thanks so much!

What's the best way to install full ROS melodic without all the voxl-suite packages being uninstalled due to dependency conflicts (e.g. opencv)?

[sarahl]

Also, how should mavros (px4.launch) be run with the internal px4 on the voxl2?
