Issue Getting Delta5 to work

[blakermchale]

I've been trying to get the app to run by following the Software Setup Guide, but when in the settings this error keeps occurring.
This only happens in the settings, and I'm unable to add pilots or heats.
None of python files were changed after cloning

Any help would be appreciated.
Thanks.

Hello,

I can confim that I have the same issue: I started with a clean install of raspbian strech Version: November 2018 Release date: 2018-11-13 and installed Delta 5 according to the instructions :"Hardware and Software Setup Instructions". I also tried different browsers: Firefox, Chrome still the same issue. I'm also unable to shut down the raspi by the gui buttons. Furthermore, all the calibration values fields are empty. The connection to the arduinos seems to work fine... (when i connect them they get shown in the setting tab. However, it is not possible to assign frequencies.)
Also the timingserver used for the connection to Livetime doesn't work.

If anybody can offer help it would be highly appreciated

Thanks

edit: i removed the sercive agian and tried to start it by python server.py in the delta5_race_timer/src/delta5server/
and the python program terminates with an error after finding the Nodes:

edit2: as it seamed at first glance like a problem accessing the database i gave the src folder a recursive chmod 777 such that all files can be accessed. Thereby, the previous error disappers however the GUI still doesn't work.

Did you notice any errors during the requirements.txt install portion? If you're looking for an easier method, there is an sd card image file made from my install on the pinned post of the facebook post. Just write it to your sd card, and it should have everything configured. Just a note my sd card was a 32gb card.

I didn't noticed any errory during the install of requirements.txt and if i ran this command again it writes out that everything is allready installed... I have no facebook account and, therfore, i will try now the image from https://github.com/spuder/pi-gen

The image from https://github.com/spuder/pi-gen did not work either...

However i tried a new install of raspian and it worked now.
I have no clue what i made different.
Thank you for your support

Hi Scott, I'm getting similar issues.

I've got it working now. Not quite sure how, but here are some of the steps
I downgraded from the RPi 3 Model B+ to the standard RPi 3 Model B and started again. I followed all the instructions and everything went well without errors. But the web server still wouldn't serve.

I then removed the whole delta5_race_timer directory
rm -r ~/delta5_race_timer
... and reinstalled it
cd ~
git clone https://github.com/scottgchin/delta5_race_timer.git
cd /home/pi/delta5_race_timer/src
sudo chmod 777 delta5server
sudo reboot

After the reboot, it all sprung to life.

I'm not sure what went wrong, but I think the database got corrupted in the first install and the second re-install started with a clean one.

Maybe, I'm missing the mark, but anyway, in case it's any use to anyone else, this worked for me (after a lot of trial and error).
