@mklemarczyk ah, I see what you mean now. Let me revisit the code to get back into it. No promisses.

I have implemented the above in https://github.com/lathoub/ArduinoBLE (device and char callbacks). I'll add some callback examples now, to see how it behaves (but i will need help on this, I'm...

added examples ([central ](https://github.com/lathoub/ArduinoBLE/blob/master/examples/Central/ScanCallback/ScanCallback.ino)and [peripheral](https://github.com/lathoub/ArduinoBLE/blob/master/examples/Peripheral/LEDcallback/LEDcallback.ino)) , but i don't have the hardware here, so need help testing

@mklemarczyk gentle nudge

I have an ESP32 WROOM32 talking happily to a W5500, using the std Ethernet library with CS pin on 5 of the ESP32 and SCL on PIO22 (not on your...

sample output: ``` ... 11:22:22.527 -> 0x90 0x4C 0x40 589 11:22:22.948 -> packetSize: 3 11:22:22.948 -> 0x90 0x4C 0x40 590 11:22:23.398 -> packetSize: 3 11:22:23.398 -> 0x90 0x4C 0x40 591...

@Rotzbua no memory is dynamically allocated in the above example. Only static memory is used in `packetBuffer`. (I don't know what happens in the Ethernet library)

@Rotzbua thanks - I installed the suggested [MemoryFree](https://github.com/mpflaga/Arduino-MemoryFree) library and printed the `freeMemory()`. No memory leak, stable at 2292 bytes (all using genuine Arduino hardware) ``` 17:40:52.886 -> packetSize: 3...
