Node-Red USB-sensor

Hi,

I'm trying to capture sensor data from an http://www.magnet-physik.de/fileadmin/Mediendatenbank/1_Produkte/2_Messtechnik/Datenbl%C3%A4tter/HU_... USB-sensor.

My first idea was to do this with Node-Red.

Now I got conformation that the sensor is or not connected. But I didn't get any data out of it. I tried to do the same as in https://github.com/intel-iot-devkit/intel-iot-gateway/tree/master/Getting%20Started%20With%20Node-Re... this project what is very similar to mine. But the debug output shows "Error: Error: Invalid argument, calling write" Probably because my sensor is acting else than the sensor used in the example project.

That's why I start sniffing on the sensor data (connected to an Windows desktop for the test), and I god following packet captured:

Still not enough useful to me to determinate how I can work with the serial input from Node-Red, but maybe this information helps someone over here?

My second idea is to work with a python script. So I installed pyusb with an pip install. According to this Github manual, I tested the example script and end with an error "usb.core.NoBackendError: No backend available"

Hi, Belekz

 

 

Did you check this thread? https://github.com/pyinstaller/pyinstaller/issues/1891

 

I think you will find some useful information there.

Hi Belekz,

Take a look at https://www.intel.com/content/www/us/en/support/articles/000020775/boards-and-kits.html Shield Testing Report for Intel® Galileo Board, Intel® Galileo Gen 2... for "known issues for shields and sensors executed on an Intel® Galileo development board". I think that you'll have many problems if your sensor is not listed in that Report.

BR,

Fernando.

Wouldn't there be a way to capture this data via Node-Red? I'm waiting on a reply from the manufacturer for more information about how I can distillate the data from the packages.

Hi Belekz,

 

 

As FGT stated, if the device is not listed in the report, it may require some work on your end to get it functioning.

 

The manufacturer can help you with this issue.

If possible, yes. We are currently looking after plan B which include an Windows platform. But it still should be better if there a solution occurs that work with Node-Red.
