dear all:
I want to control a LED Server by GET method, which can turn LED on/off and get the LED state form server via HTTP response. This idea was verified by Node-RED and work well:
As above,when ON/OFF Button is click, a get request is send to server with payload(/? ON or /? OFF). By analysis the payload, the MCU of sever can set LED's state and response it to client!
Now, I am trying to porting this idea to App Inventor such that LED server could be controlled by phone!
But I do not know how to add the payload to the get request when use web component of App Inventor.
This is my first post. Looking for help.
Regards,
