WJ2 for blinking LED on a Webserver

Added by Renato Giugni RG 12 months ago

Greetings,

I'm using WJ2 commercial license.

My project is to turn and LED on and off based on a webserver, similar to the tutorial example from Aimagin Model-Based Design for IoT.

My problem is that when I access the webpage and click the 'ON' and 'OFF' button, the ESP32 webserver only updates the LED status a few times, like 3 or 4.

After that, it just stops working.

I'm using ESP32 SPIFFS memory.

Could anyone help me please?

Hi Renato,

Thank you for reaching out and apologies for the delayed response.

It's hard to tell where the problem lies without seeing your Simulink model and HTML/JS code that you have written. Have you tried this example already? Is it working as expected for you?

If yes, have you tried to compare from our Simulink model and HTML/JS code to see what is different?

Sincere regards,
Parth
