Are there any examples on how to use the “Expression” element in the Application view? I know how to use regular expressions but not sure how to use this IDE element to accomplish a simple task.
I want to check if the string value I am getting from the Buzzer via the BLE Characteristic is “true” or “false”.
I tried setting the expression field to
readData=="true" but no luck.
I would share the .atmo file but this form won’t let me add anything other than image files. Here is a screenshot of what I mean:
In the above example, the
Label field correctly updates to
false depending on the buzzer state that I set by pushing a button. I am using the same thing to feed the Expression element.
Any ideas or help would be greatly appreciated.
