Although it is already visible here from the linkback, I'll also add a comment here to highlight the presence of an issue report from a tester of the version of the library from this PR on the UNO R4 WiFi:

#309

Thanks for helping with the testing of this PR @MicheleMas!

There is some feedback from a tester here:

https://forum.arduino.cc/t/arduinoble-doesnt-work-inside-library/1148979

Running the code on Nano 33 iot all the characteristics are present and everything works as expected:

[...]

but when it runs on Uno R4 WiFi the custom characteristics are not included in the service:

There is a report from a tester of the version of the library from this PR on the UNO R4 WiFi here: #311

advancement on my side in testing. code below fails when BUG_HERE =1, but succeeds when BUG_HERE=0

hope this helps, and thank you!

There is a report from a tester of the version of the library from this PR on the UNO R4 WiFi here:

https://forum.arduino.cc/t/uno-r4-wifi-disconnecting-reconnecting-continuously-when-running-sketch-w-led-matrix-and-arduinoble-libraries/1154103

They report that the BLE connection keeps disconnecting and reconnecting continuously when a call to ArduinoLEDMatrix::begin is added to the sketch.

There is another report from a tester about problems with the use of this version of the library in combination with the "LED_Matrix" library on the UNO R4 WiFi board:

https://forum.arduino.cc/t/uno-r4-wifi-disconnecting-reconnecting-continuously-when-running-sketch-w-led-matrix-and-arduinoble-libraries/1154103/12

Quick note: On the forum thread https://forum.arduino.cc/t/uno-r4-wifi-disconnecting-reconnecting-continuously-when-running-sketch-w-led-matrix-and-arduinoble-libraries/1154103/12

There was report of another library that when it was included, exhibited the same problem as the LED Matrix. But at least in the latter case, pulling in the updates to analog.cpp for the heap corruption bug, resolved that one. Not sure about the LED matrix one

Any updates on when this might get merged?
