How to connect without ClientID? #22

Closed 1115william closed 3 months ago

It needs a clientID to initialize the Network::Client::MQTTv5, but if we don't have clientID, how to connect to the server? for example, connect to a remote broker.

That's not a problem. You can pass a NULL (nullptr or 0) value for the clientID in the constructor and it'll just use what the broker provides.

The documentation in the MQTTClient.hpp states:

@param clientID     A client identifier if you need to provide one. If empty or null, the broker will assign one

I'm not building the doxygen documentation by default when you build the library, so you might miss it.

In that case, I invite you to visit the documentation size for a better description of parameters and what is supported.
