@kl3m3n sure but unfortunatly I'm using an esp32-S3 on my custom hardware

Best regards

I will send you the code for my esp32 .

via network it's works perfectly with the software for windows.
unfortunatly via esp32 I have only BLE.

@kl3m3n by adding 200 of delay looks good. But no very efficien I didn't find an acknoledge mecanism in the api .

And with this time out I receive message "No response from remote device"

I'm not an software expert I'm hardware designer and frankly speaking I don't know exactly the behaviour if I change the connection settings.

void sendMsg(const String &msg) {
  // Set value and notify the client
  Serial.println("Envoi du message : " + msg);
  pCharacteristic->setValue(msg.c_str());
  pCharacteristic->notify();
  delay(DELAYSENDMSG);
}
//with delay at 200 

if I put delay each 3 instruction the issue is the same

Hi everyone,

I'm currently working on a project using an ESP32-S3 to send data and commands to the GUI-O app over Bluetooth Low Energy (BLE). My code creates a series of widgets in the app, but I'm facing an issue where only a maximum of 29 widgets are successfully displayed in the GUI-O interface. Any additional widgets beyond 29 are missing.

I've set up the widgets using commands like sendMsg() that are sent to the app over BLE. It seems that not all widgets are properly received by the app, even though all the commands are being executed in the code. I suspect it might be due to BLE packet size limitations or possibly some commands being sent too quickly for the app to handle.

Here are some key points:

The commands are sent from an ESP32-S3 using BLE.
I'm sending a long list of widget creation commands, but only 29 widgets get displayed.
It looks like some of the messages are getting truncated or lost, as additional widgets beyond the 29th don't appear in the GUI-O app.
The BLE message size limit may be around 512 bytes, and I’m trying to figure out the best way to fragment these commands to ensure all widgets are properly created.
I've already tried adding delays between the commands (e.g., delay(50)), but the issue persists. I’m wondering if there's a better way to manage this, such as breaking up the message to fit within BLE packet limits, or another approach to guarantee that all widgets are properly rendered.

Any advice on how to ensure all BLE messages are successfully received by the GUI-O app and all widgets are displayed would be greatly appreciated!

Thanks in advance for your help!
