Managed to decode data, but when I manually tested the process_meteor.py it failed when copying file to /tmp/.satnogs/data/complete/

Is it simply due to observation being performed over an hour ago? Or is it something that should be fixed?
Yes, your code improvement makes sense if you want keep the files. But the tmp folder is in memory as far as I know. Could get full, so I decided to remove them. See step 5 of the instruction.
To solve the ir image problem you donāt need to look at the computer monitor, but need to look outside during the observation. If it is light outside, the ir channel is off and the image gets black. I assume it starts working again when the winter arrives in
Makes perfect sense, Iām still in awe how beautiful those pictures are. One thing is when I add the process_meteor.py script as post observation script something seems off and after decodes I get a long series of failed observations afterwards where no products were uploaded - is this connected to what you mentioned that itās getting full?
Hi, in the update from 1.4 to 1.5 there was new functionality introdced in Satnogs that caused trouble. I had updated step 1 of the howto to include some arguments to satnogs_lrpt_demod.py. So please check this file against the instructions of step 1. Start at: sudo nano satnogs_lrpt_demod.pyā¦
And it is good that you have already updated flowgraps.py. I think there are no changes needed in postob.sh or the menu.
Need help since the upgrade to 1.6
I have a syntax error and i canāt tell why so please see pictures of flowgraphs.py and the dump/log file and help a guy out whoās stuck please.
So yet another issue. while observing the Meteor-M2 pass i see no waterfall data and the log file shows as in the picture below. This time Iāve looked at both stations i have running and they both look the same so please see the attached picture and if you can shed some light on my issue with that would be great.
I have noticed that the def argument_parser() : is not all the way to the left of the screen on the file could this be it ? and how important is the spacing.
Well it took a while but itās finally fixed and Iāve got the first successful observation, Time to schedule some more.
Thanks for all the help.
It is very important! Python uses the spacing to determine which lines belong to each other. Other programming languages are more dependent on brackets or key words, and not to spaces.
Yes the start looks just like yours and end looks like the second picture above.
Itās back to working.
One other thing i had to do was edit the complete_output_path in the satnogs-setup options as this is the only way i could get the complete folder to stop deleting itās self on reboot or restart.
Hi Elke and allā¦
what is needed to be done to get the LRPT-demod in to āSATNOGS-clientā?
So we do not have to do allthis when the next upgrade comes along.
I think the issue is that we use post processing after the observation. I read somewhere (where?) that this is undesirable, as it might interfere with the next observation.
There is some work tracked in this item LRPT Decoder (#122) Ā· Issues Ā· librespacefoundation / SatNOGS / gr-satnogs Ā· GitLab to include it. It seems āpausedā, and I donāt know the status.
If it is light outside, the ir channel is off and the image gets black. I assume it starts working again when the winter arrives in
