Description

When attempting to set the operating frequency of a BBox One using the TMYTEK BBox API DLL from LabVIEW, the function will always fail and return error code 2 ("Generic Error"). When attempting this same function call from Python it executes successfully and I am able to change the center frequency/operating frequency. I am also successful in changing the center/operating frequency of the BBox from the TMXLab software on the same computer.

The generic error code is always returned, and the center/operating frequency is never changed when invoking this method in LabVIEW. Using the example program provided in this API repository returns the error, as well as running example code provided by NI (National Instruments) and invoking the method on my own in a very simple VI.

I believe this may have to do with numeric type casting/handling between LabVIEW and the TMYTEK API DLL, although I can't be sure since I do not have any insight into the source code behind the TMYTEK API DLL. When first loading the example code in LabVIEW, the BBoxOne.vi will throw a warning stating that the .NET Assembly being referenced has changed versions, from v3.3.8.0 to v3.3.18.0. Maybe something changed between those versions of the DLL that caused this example code to break, but again I can't be sure.

Steps to Reproduce

1. Download or clone the bbox-api fresh from origin
2. Run the LabVIEW example provided (bbox-api-master/example/BBoxOne Series/LabVIEW/BBoxOne.vi)
3. All other methods will execute successfully except for setOperatingFreq (returns code 2)
4. If you use the method getOperatingFreq, it will always return the default operating freq for the device you're connected to. (In my case, the BBox One 5G 28GHz will always return 28 GHz)

Expected Behavior

setOperatingFreq should succeed and change the operating frequency

Current Behavior

Operating frequency does not change from default - as witnessed by running getOperatingFreq - and setOperatingFreq returns error code 2.

Description

When following the set-up instructions for the example code in Python, the packaged installer (bbox-api-master/pre-install/Python/python-3.7.7-webinstall.exe) installs Python 3.7.7. However, when trying to run the Setup.bat file to install the required packages, this fails because numpy 1.22.0 is not compatible with versions of Python below 3.8.

In order for the Setup.bat file to execute successfully, you must install Python 3.8 and run the Setup.bat so pip can install the required packages.

Steps to Reproduce

1. On a fresh PC without Python installed, clone or download the bbox-api project
2. Install Python from the included webinstall.exe file (bbox-api-master/pre-install/Python/python-3.7.7-webinstall.exe)
3. Run Setup.bat
4. Setup will fail

Expected Behavior

Setup should complete and install the required packages

Current Behavior

Setup fails

Description

The latest release of the TMYTEK bbox-api library has all of its examples saved in LabVIEW 2022 Q3. For greater application and development accessibility and compatibility, the examples should be saved for an earlier version of LabVIEW.

The documentation/readme for this library states that LabVIEW 2021 is the tested/prerequisite version of LabVIEW for the API examples, which is no longer the case. This affects all of the example LabVIEW project files and VIs, not just the BBox One examples.

This can be fixed by simply opening the projects in LabVIEW 2022 Q3 and saving them for an earlier version of LabVIEW to maintain backwards compatibility

Steps to Reproduce

1. Download the latest release of the TMYTEK API Examples
2. Attempt to open any of the LabVIEW project files or VIs in LabVIEW 2021
3. LabVIEW will report an error that the file version is later than the current LabVIEW version

Expected Behavior

The example projects and VIs should open in LabVIEW 2021

Current Behavior

The example projects and VIs are saved in LabVIEW 2022 Q3, which means they are incompatible with LabVIEW 2021
