As one can see below, before a connection is lost, the subscriptionCallback (without the underscore) is called periodically from Basic.ino.
subscriptionCallback
Basic.ino
After the _reconnect method is called the subscription callback defaults to _subscriptionCallback (with the underscore) in WifiMQTTManager.cpp.
_subscriptionCallback
WifiMQTTManager.cpp
There is a line I don't understand: subscriptionCallback = _subscriptionCallback;
subscriptionCallback = _subscriptionCallback;
Also, this line: subscribeTo = _placeholderSubscibeTo;
subscribeTo = _placeholderSubscibeTo;
Any tips appreciated, thanks, Chris.
