Unit firmwared.service could not be found

[Neil]

This is what I receive as error message from

sudo systemctl start firmwared.service

I have a source installation of Olympe on a 20.04.4 generic aarch64 image.

Olympe SDK working fine.

What can be wrong?

[Neil]

Trivial reason: I didn’t install sphinx.

Now I’m having sphinx up and running on an Ubuntu 18.04 laptop. I can reach the dashboard from my client computer, but I can’t connect the drone.

The sphinx box has two interfaces: Wifi and eth

I made a “stolen interface” mapping entry from wlp2s0 to eth0 and noticed to have a new eth0 interface after start of the simulator, but it also doesn’t work w/o it, like:

sphinx /opt/parrot-sphinx/usr/share/sphinx/drones/anafi4k.drone::stolen_interface=""

However, I was supposing to be able to reach 192.168.188.73 from my drone script, but the output is always:

2022-06-06 07:15:19,071 [ERROR]         olympe.drone - connect - '192.168.188.73 connection timed out

Is there anything I can investigate on the simulator side? As said, I’m reaching the dashboard at 192.168.188.73:9002, there is also no firewall applied.

[Neil]

Hmm. I started the simulator with “–log-level=dbg” and found this

First is the Wifi, second is Docker, third is ETH. Is the simulator listening to the wrong interface?

[Neil]

Again some misunderstanding on my side I guess:

I didn’t find that fd_blabla interface after all this and learned from the troubleshoot section, that I have to disable my NetworkManager service in this case. Worked after that. Had thad interface.

Still not clear, how to reach the simulator from outside. I suspect I would have to have a direct link between both machines and a fixed IP configuration on the client side to make this work. Or I need to run the scripts on the same machine on which the simulator runs (?).

At least it reacts on that machine:

decades@ubuntu:~$ telnet 10.202.0.1 44445

Having now all on the same machine (SDK and simulator) and it works.
