update 0.65 problem

[kalamar67]

Hello, after the last update, the aiscatcher no longer sees the rtlsdr. No matter what I did, I couldn't get it to work. Can you help me?

Some other process is using the rtlsdr, most likely. Can you check with ps -ef if anything stands out that might be using the stick?

[kalamar67]

Of course, I checked this many times, the issue is not the catcher installation, it is already installed and working properly, whatever happened in the webgui, it keeps giving this error and does not run the system.

can you show config.json and config.cmd?

config.cmd

AIS-catcher configuration

[kalamar67]

The problem is actually like this: Aiscatcher works fine on Raspberry Pi 4, there is no problem, but the GUI perceives it as if Aiscatcher is another program and it is using rtl.

[jvde-github]

There is an issue with the config.json which makes it use two dongles. I will fix for you later today in some free time

[kalamar67]

thank u so mach

Ok, so your config.json defines two receivers (one at root level and one in the receiver array). The GUI tool only looks at the receiver array but should migrate anything that is in the root of the config to the array (bit of a legacy way of configuring as initially I was only supporting one array). That is why you see only one receiver in the Input section.

Can you update the control tool with "Upgrade Control Panel).. Then restarting should automatically upgrade your config.

I have tested with a config similar to yours. When I start with the updated Control Tool I see:

If you now go to the Input section of the Control tool, you see two receivers. My suggestion is to delete one of them, save, and restart the program. Hopefully will resolve your issue. I am still not clear how your config could end up in this half state....

I will close this assuming it is solved, otherwise let me know and we have another look! thanks for raising, much appreciated.
