UAVcast. Software for Companion Computer based UAV`s

Sinamics

Vootele_Aer I dont think so. Try to install in /home/pi/ if you not already done so.

Thanks a lot for your work on this @Sinamics , great project!
I'm looking for some help to get this running on a RPi0w. I've got it all working already on a RPi 3b running Jessie following your default instructions. I have also followed the default instructions with my RPi0w several times over, using Jessie and a few different OS images, but I keep ending up stuck at the same point. Uavcast runs on reboot and streams the video fine (once I manually enabled the pi camera), but it is not sending telemetry.
At the Home tab I get the red error message:

"Ooooops!!! We have a problem!"

cmavnode: error while loading shared libraries: libreadline.so.7: cannot open shared object file: No such file or directory

I'm certain that my wiring is ok, it runs straight away when I plug the RPi 3b back in. There's no sign of any incoming telemetry in mission planner when using the Pi0w, whereas the same GSC endpoint using the same Mission planner works fine with the RPi 3b.

Can you please help me out to get this running on the Rpi0w.
Any help will be much appreciated, cheers.

Hi BlakeEdwards

Seems like you have some issues with shared libraries.
Make sure you have not installed UAVcast using your alias home directory. ~/
Type cd /home/pi and the install UAVcast again.

Sinamics
Thanks for the quick reply! Unfortunately that doesn't see to have made any difference.
I'm SSH'd into my pi using Putty, where the default is to display 'pi@raspberrypi:~ $'. Running 'pwd' from here returns /home/pi, and running 'cd /home/pi' doesn't seem to make any difference
When I run 'CD UAVcast/install' this turns into 'pi@raspberrypi:~/UAVcast/install $'
I've tried a full re-install after running 'cd /home/pi' and it hasn't fixed the issue.
Any other ideas what it might be?

Sinamics

BlakeEdwards Strange..
If you could open port 22 and give me your public IP, i can login and have a look.
just send me a PM on discord.

Sinamics

@mocart did you ever encounter this issue with your Pi0w?

mocart

No. I did not have any problems with piow telemetry installing it on fresh and new system. The only one time when I observed problems with telemetry was related my tests on multi uav configuration. I did make too much changes related mavlink parameters and finally qground control stops work after that 🙁. After pixhawk reflash telemetry started again. Ports are corectly assigned this rpi? Maybe he need to swap ports?
If you want compare settings I can share my pi for you.

raspberry pi 0 would work? i have 250frame and i put pixhawk and rpi3 but there isn't enought space, so i have to put smaller raspberry pi or switch to APM flight controller who is more little than pixhawk, suggestion?

mocart

Pi0w works well and you have wi-fi module onboard so setup will be more easy using "w" version I think.

Kekko991

mocart i want to use 4g network

mocart

I'm using 4g when I'm outside home.
When drone is in home wifi area much better to setup it using wifi 🙂. For pi0 Bernt probably need to add pi0 id to script and it should work. My recomendation ... just buy pi0w. It works, and prices are not so different.

Kekko991

mocart i already own a RPI B

i have to change 250 frame or buy an APM who is more smaller than Pixhawk , but what it's the difference between pixhawk and apm?

mocart

Kekko, are you asking about model B or PI0? Pi0W and Pi0 are very similar but not the same. There is a Chance you can run it casting software on it. Model B is completly different. Have you got model B or Pi0 as you wrote in previous post?

I'm looking for some help to get this running on my RPi3B+.I've got it all working already on a RPi3B+ running Jessie following your default instructions. I have also followed the default instructions with my RPi3B+ several times over, but I keep ending up stuck at the same point. Uavcast can't run yet,although I have pressed the button "START" on the home page several times.

Can you please help me out to get this running on the Rp3B+😀.

Hi
The reason why it wont start is your network.
Network is not available, waiting..

Can you ping google.com? or your ground control station? from RPI.

hzzfly

Sinamics Thank you for your reply.It‘s inconvenient to ping google.com.It is limited to connect to the international network,but we can ping baidu.com. Can you tell me how to make it work?😉

Sinamics

hzzfly go to the main UAVcast directory. cd home/pi/UAVcast
type this command git pull

Then try to start again. I just pushed a small fix for that issue.

hzzfly

Sinamics Thank you very much!😀I will have a try.

hzzfly

SinamicsThanks for your help!But there may be another problems.😅

hzzfly Have you selected Flight Controller type and GCS information in the settings.
Could you explain your setup?

David

hzzfly Same problem tested in Raspbian lite and desktop and same problem always...
