Error when running gm1356
Hi, I am getting this when I run the gm1356. Any hints as to what I am doing wrong?
pi@raspberrypi:~ $ gm1356
Traceback (most recent call last):

Thanks!
Importing recorded readings (SoundLab software)?
I am interested in downloading the recorded readings from the GM1356 - I can try sniffing the USB communications myself, but I have not found the original SoundLab software available anywhere...
Is there a download link for the mentioned working version anywhere (Sound Level Meter v. 1.0.0.20, build 2016-07-20)?
Libusb busy
After successfully recording for a time, I sometimes get the following:

Any hints?
Do you have a link where I can buy the product this driver is tested on?
Great work on this driver!
I have a problem similar to that of @HaasNL2 in the other issue. A big industrial plant is being built next to my home, and I need to document the noise. I plan on mounting the decibel meter outside my house, wire it to a Raspberry Pi, periodically push the data to GitHub, and use GitHub Actions and Twitter API to automatically make a tweet every time the noise exceeds the law, and tag relevant politicians in the tweet. I plan to run it 24/7. If you immediately see a technical reason that this will not work out, it would be great if you let me know ;)
Do you know where I can buy a device which this driver is known to work on? The README.md specifies serial number HA:1303162, but I can't find a product listing when I google it...

How to reduce the load on the cpu?
USB URB solved ?
Hi@ciembor, I saw your query on https://gist.github.com/ciembor/d6d1ae2b5b2c329c378b68112f75809d and believe you somehow managed to close that point. I'm facing the same issue in shaping a 27byte long request, was wondering if you could share your solution on this?
Is this for loggin noise?
Hey,
I also have this meter, first I was just going to use Windows. But the lack of any autmated logging is a bit worrying.
Can you use this to log the data? Can I send it to a webserver?
