I understand, well, always i can use
ESP.restart() after a disconnection to bluetooth
, it's horrible but for the moment is what I can do.
Essentially I think that you are absolutely right, if it fails in the second connection with bluetooth and it works again when I disconnect it is because there is a conflict of channels, on top of that if it is something that I cannot control well ...
Well, thanks for the advice man, it has served me well to clear doubts
