Issue with Sending Data to ESP32 After Multiple Button Presses in App via HTTP local server

Hello,

I am working on a project using an ESP32, an SD card, and a MAX98357A codec to play MP3 songs. I am building a mobile app to control the volume via a local HTTP server.

The app is intended to send thumb position data to the ESP32 whenever a button is pressed. However, I am encountering an issue: after pressing the button 7 times, the app successfully sends the data as expected. But after the 8th button press, it stops sending the data. When I close and reopen the app, it sends all the data at once.

It seems like the app is holding the request after the 7th button press, and Iā€™m unsure why this is happening.

I have attached a screenshot of the blocks for reference:
MIT APP INVENTOR

Has anyone encountered a similar issue? Can someone explain why this might be happening and how I can resolve it?

Thank you in advance for your help!

Best regards,
aas
