Error in Launch your first simulation

Hello everyone, I installed Sphinx on Ubuntu18 64bits and when I execute the instruction:

$ sphinx /opt/parrot-sphinx/usr/share/sphinx/drones/anafi4k.drone

I get the following error that is not resolved:

[Msg] Selected params to build .sdf file for anafi4k:
param low_gpu = 0
param product_pro = 0
param sdcard_serial = __undefined__
param simple_front_cam = 1
param with_external_cams = 0
param with_front_cam = 1
param with_gimbal = 1
param with_kalamos = 0
param with_tof = false
param xmlns =

[Wrn] [Telemetry.cc:35] Cannot open libtelemetry from remote firmware

In the process I get to see the ANAFI drone in the Gazebo simulator, but after the error it closes abruptly.

How do I solve this error? I have searched the internet but I have not yet found the solution.

Thanks in advance, I’m new to Parrot.

Hello,

This error can be ignored. Do you have more logs after this?
Is your stolen_interface properly configured? By default, it is configured to search for a wifi interface named wlan0.
Have you tried without the front cam?

Yes, this is the log until closing:

Solved

You must know the name of the connection interface with the command:

$ iwconfig

and then simulate our drone with stolen_interface

$ sphinx /opt/parrot-sphinx/usr/share/sphinx/drones/anafi4k.drone::stolen_interface=<your_interface_name>:eth0:192.168.42.1/24

The problem with this is that if you are using a computer and you don’t have a Wi-Fi USB stick or something, you run out of internet!
