Setting up new connections with Rae

mjohannessen

A fresh install of the Rae OS has an /etc/wpa_supplicant.conf file but no /etc/systemd/network/20-wifi.network file. Out of the box there are two ways to connect to the Rae - via usb (ssh root@192.168.197.55) and the re-<id> access point (192.168.11.1). Am I correct that by adding a wifi network per the instructions at https://docs-beta.luxonis.com/hardware/rae/get-started?v=Advanced+(manual) creates another access point which seems to occur with this instruction:

systemctl stop hostapd
wpa_supplicant -B -i wlp1s0 -c /etc/wpa_supplicant.conf
systemctl restart systemd-networkd

If so, what is the purpose of adding this additional wifi access point? What additional functionality does that enable?

Also, the docs say there is a webserver running https://<IP of RAE>:9010. I see by scanning the ports 192.168.11.1:9010 and 192.168.197.55:9010 there is a tcp process running, but a browser cannot connect to those addresses.

root@rae:~# fuser 9010/tcp
789 
root@rae:~# ps -p 789 -o comm=
node

Looks like this is the .vscode server though.

mjohannessen SOLVED partially. Adding the additional WIFI enables https://<IP of RAE>:9010 for local control. Still, the browser gets stuck on "Waiting for stream ...", although the lights, motors and face can be controlled.

Also, by doing this:

robothub-ctl stop
robothub-ctl startup disable

Disables https://<IP of RAE>:9010. To re-enable https://<IP of RAE>:9010:

systemctl stop hostapd
wpa_supplicant -B -i wlp1s0 -c /etc/wpa_supplicant.conf
systemctl restart systemd-networkd

After this, I connected the rae to RoboHub using the generated QR and after doing this I could no longer control the rae using https://<IP of RAE>:9010. On robohub.luxonis.com I see that the RAE-Default App build failed. I don't know why the default when connecting to robohub is to try to install an app on the device. In any event, I uninstalled the app and installed the RUN version of the RAE-Default App. That app tries to start but stops:

5:22:44
ERROR | on_start:151 => The default app requires an assigned device to run. Please go to RobotHub, navigate to the app's page, click the "Reassign devices" button and select a device.
15:22:44
INFO | on_stop:173 => Stopping the app...

I cannot reassign the device because rae is not listed using the Reassign Devices button on the webpage. I tried uninstalling the app via robohub and completely removing rae from robohub, and rebooting rae and logging in locally at https://<IP of RAE>:9010. Now the rae is non-responsive but tries to connect to robohub and there appears to try to install something.

So how can I remove whatever was installed via robohub?

Hi mjohannessen
Had the same issue

mjohannessen The default app requires an assigned device to run.

which was solved when reassigning the device. The rae should be available. Is it not online on RH?

You could try manually stopping/restarting the rh agent (https://docs-beta.luxonis.com/deploy/robothub/install-agent/).

If you are stuck the easiest way would be to factory reset the device.

Thanks,
Jaka

The rae is "online" and the RAE-Default App is loaded. The app is stopped with the log showing:

6:21:42
INFO | on_stop:173 => Stopping the app...
16:21:45
[2023-11-11 00:21:45.627] [depthai] [warning] USB protocol not available - If running in a container, make sure that the following is set: "-v /dev/bus/usb:/dev/bus/usb --device-cgroup-rule='c 189:* rmw'"
16:21:49

To restart the RH agent, I think you mean

robothub-ctl restart

I did that and the issue persists - the rae does not show up as a device to reassign ("You have no available devices to assign to app").

As a side note, after a hard reset and setting up just the local web control, that works, but as soon as I try to add the rae to RH, the local web control breaks.

Hi mjohannessen
Any chance you have more than one app installed? Also make sure the FW is the stock one (1.12 OS and 23.223.1855 for the agent version).
This is a non-standard issue, I'd suggest writing to support@luxonis.com, perhaps we need to fix this manually.

Thanks and sorry for the inconvenience,
Jaka

As to OS:

root@keembay:~# cat /etc/os-release
ID=luxonisos
NAME="Luxonis OS"
VERSION="1.12"
VERSION_ID=1.12
PRETTY_NAME="Luxonis OS 1.12"

IMAGE_REV=d238da346188461703c25a3b2e5dea32b196ad2b
BUILD_ID="20230811201312"

As to the agent version:

Without going to RH, is there a terminal command to obtain the version of the agent?

As to apps running, the only app installed was the default RAE-Default App through the RH provisioning process.

Note the CPU usage. In addition the device is very warm:

Hi mjohannessen
Everything seems to be installed correctly. Please write to support@luxonis.com so we can sort this out. Also link the discussion so we don't have to go through the whole process again.

Thanks,

Support bounced this back to this forum as more team members are here. This is a description of the problem I am having to correctly provisioning rae with the default app and enabling basic functionality using RobotHub.

Here is a rundown of the issue starting from a hard reset::

Hard reset, remove existing rae from RH including events
Connect via USB > ssh root@192.168.197.55 OK
rae-<id> is visible and I can > ssh root@192.168.11.1 OK

nc -vz 192.168.11.1 9010
Connection to 192.168.11.1 port 9010 [tcp/*] succeeded!

5: https://192.168.11.1:9010:
Camera streaming fine (large (front left) and small window (rear right))
No motor control though

Any help here?

mjohannessen
There was an issue in the frontend; we have released a patch, so you should now be able to reassign the device.

Thanks for the extensive information you have provided.

Regards,
Jaka

mjohannessen

Thx - I was able to reassign with this fix.

Issues with Local Frontend:

Edit Face - blanks the screen (lit but no graphics)
Edit Lights - works
Motor control - works
Edit mode manual and follow me - work
Live View - no video

Same issue with local control https://192.168.1.64:9010.

Regarding no video stream, I opened ports 5349 and 3478 - no effect
