Xiao esp32s3 and BLE setValue() / notify() issue

Products & Technology Bluetooth Low Energy

Note: Cannot post my own code. Get error ‘403’.

In any case, the server code is a version of the Arduino * notify* example code.

Server code snippet:

  // Update the value periodically
  value++;
  pCharacteristic->setValue(String(value).c_str());
  pCharacteristic->notify();  // Notify clients of updated value

The client implements the regular notify callback:

    if(pRemoteCharacteristic->canNotify())
    {  pRemoteCharacteristic->registerForNotify(notifyCallback);
    }

The result is that there is no notification taking place. All else is working well. I wonder if there is a known issue with the esp32s3 board and the current Arduino (IDE v.2.3.6) Espressif board manager (v. 3.3.0) and/or the current BLE stack.

On the other hand, if you do have a simple proven and working example of an Arduino client/server BLE code and would like to share it, that would be great. I cannot share/post my own code for some reason.

Thank you. Most appreciated.
