Can't get server to autostart on boot #18

Open Regenhardt opened 2 years ago

Regenhardt commented 2 years ago

Hi,

not sure why, hope you can help me. I followed the tutorial.pdf, but it won't automatically start.
Manually calling sudo python main.py -tn starts the server and works as expected.

After following the tutorial exactly and it didn't work, I manually executed the start.sh and an error was displayed that it couldn't connect to display, which makes sense since I used ssh. So I added -tn to the call in the start.sh and now it works if I call it manually.

Since the point.txt isn't copied to ~ when rebooting, I guess start.sh isn't even being called, but I don't know why.

Here is a screenshot of the actual file contents and ls output to show the executable status:

Oh so the server only autostarts when I login to the desktop? Can't I autostart it whenever I start the raspberry pi?

so the instructions aren't clear. Where you see ".../pi/..." you should replace with your username. For me it was ".../Peter/...".

no it starts logged in or not

DenzelChen commented 2 years ago

no it starts logged in or not

It can start without login.

No worries, my user is indeed called "pi" (as you can see in the screenshot).

When I follow the video exactly, the server only starts when I login to the desktop.
Starting the raspberry pi does not start the server (legs aren't activated).
Logging in using ssh also doesn't start the server.
As soon as I login to the desktop via RDP/VNC the server starts and the legs are activated, just like in the video you linked earlier.

It can start without login.

How? Do I need to add anything that isn't in the video you linked earlier?

Add -tn after sudo python main.py to try.

Add the following contents to “start.sh” file.

!/bin/sh

cd "/home/pi/Freenove_Big_Hexapod_Robot_Kit_for_Raspberry_Pi/Code/Server" pwd sleep 10 sudo cp point.txt /home/pi sudo python main.py -tn Press Ctrl + O and then press Enter to save it. Press Ctrl+X to exit.

As mentioned in my original post, and visible in the screenshot aswell, I did just that - add -tn to the call so it doesn't open the window. Unfortunately nothing happens until I login via RDP/VNC.

To further test this I even tried adding sudo python test.py buzzer to the start.sh just before starting the main.py to have an additional cue, but that one didn't happen either. So I figured it must be the file being called at all, but since I usually don't use Linux I'm a bit lost here.

Can you use the commands to start server without window successfully?

  1. Use cd command to enter directory where main.py is located: _cd ~/Freenove_Big_Hexapod_Robot_Kit_for_RaspberryPi/Code/Server
  2. Run main.py: sudo python main.py -t -n or Run main,py with following command: sudo python main.py -tn
Regenhardt commented 2 years ago

Yes, this works perfectly fine.

I can also login using ssh and then call sudo ./start.sh and the server starts as expected.

DenzelChen commented 2 years ago

Sorry I don't know the reason. It works here. I am using Raspberry Pi 4B and following OS: https://downloads.raspberrypi.org/raspios_full_armhf/images/raspios_full_armhf-2022-04-07/2022-04-04-raspios-bullseye-armhf-full.img.xz
