Hi everyone. I need to get the output message from several inputs (3 or 4 inputs). For example, I got two different mental commands which are shown in the picture below. I need to display the message based on which mental commands I'm receiving. When the 'left' command is received and the sensitivity is over 30, the message 'left' will be displayed. If the sensitivity is less than 30, then the 'no signal' message will be displayed. It works fine with only one mental command in the flow. When I add the second mental command in the flow and want to compare the signals from the two commands, the output can only display the message from the second command.
How can I do the comparison and choose the right one from different commands? Can I use the join node to do it? I've tried the join node but the debug message shows the error messages like below.
Any helps will be appreciated. Thank you.
