Issue Details

I'm programming on C# and I want to use the RFSG WLANG Multiple User Waveform function.

But, I am getting the following error when trying to set two users for an 802.11 ax multiple user waveform. 

 

-44443: Property Node (arg 2) in niWLANG RFSG Create and Download Waveforms (Multiple Channel).

 

Is there a setting I should not use for multiple users or a call that I'm missing?

Solution

To prevent this issue you must be sure to have a different RuOffset on both users.

 

For example, for "user0" we will assign 0, while for "user1" we will assign 1:

 

chStr = "user0";
                _wlanToolKit.SetScalarAttributeI32(chStr, niWLANGProperties.RuOffset, 0);
...
chStr = "user1";
                _wlanToolKit.SetScalarAttributeI32(chStr, niWLANGProperties.RuOffset, 1);
