Problem with "SendCommand" API method

Hello,

I have configured my FreeMASTER project with one application command, which is handled on target side. This is the definition:

And everything works as long as I use the desktop app. Now I want to send this command from MATLAB through the ActiveX server, but I fail as follows:

And I get the same error message, whatever the string I pass to SendCommand. What am I doing wrong? I have followed this piece of documentation:

What is the right syntax to use in the string I pass to SendCommand?

Regards,

Luca

Eventually I found out by myself what the right API method usage is. It seems that

pcm.SendCommand('enableLogging', '1');

works. So with the argument passed as a second parameter.

Hello,

reason for the error is another mandatory argument unfortunately missing in the documentation:

Boolean argument "wait" - set true to wait for the command processing to finish.

So the line could look like:

pcm.SendCommand('enableLogging(1)', false);

The documentation will be updated in the next version.

Thanks.
