Digital Sound Level Meter Gm1356 USB driver for Linux

GM1356 for Linux

Description

This driver was written for Digital Sound Level Meter with USB (type GM1356) serial number: HA:1303162 ordered from China via Aliexpress. My sonometer works with SoundLab Sound Level Meter v. 1.0.0.20, build 2016-07-20 delivered by Benetech Poland (thank you very much for this). I was trying to run it with SoundLab downloaded from Bogen website, but it couldn't connect to the device. It means my driver may not work with some GM1356 devices.

Installation

First make sure you have ruby interpreter installed. Then run:

gem install gm1356

Now make sure that users have access to your device. In my case I had to create /etc/udev/rules.d/90-usbpermission.rules with such content:

SUBSYSTEMS=="usb",ATTRS{idProduct}=="74e3",ATTRS{idVendor}=="64bd",GROUP="users",MODE="0666"

Then run:

sudo udevadm control --reload

And after all reconnect your device if it was already connected.

Usage

If you want to print real time data from your sonometer, run:

gm1356

For more options:

gm1356 --help

Protocol

I used Wireshark with USBPcap to sniff communication between my device and SoundLab on Windows in order to understend the protocol. Protocol is described in PROTOCOL.md.

Supported functionalities

• receiving real time data with sound level value, A/C filter, max mode, slow/fast mode and measured range
• changing A/C filter, max mode, slow/fast mode and measured range

Unsupported functionalities

• importing recorded data

gm1356's Issues

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?

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)?

CPU 100% load

When running gm1356 and top, the command takes 100% of the CPU:

How to reduce the load on the cpu?

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...

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?

Error when running gm1356

Hi, I am getting this when I run the gm1356. Any hints as to what I am doing wrong?
