Debug options #6

Closed JohnCallingham closed 11 months ago

Hi Great library. Is there any way to add debug info? Thanks John

This can be done using preprocessor defines.

Build the library with PICOMQTT_DEBUG defined to get some extra diagnostic messages printed to the serial.

Build the library with PICOMQTT_DEBUG_TRACE_FUNCTIONS defined to make the library print (almost) all internal function calls and returns to the serial. Note that this is very verbose and will slow things down significantly, but it's very useful for debugging the library itself.

You can enable these options by adding a compiler flag or un-commenting one of the lines here: https://github.com/mlesniew/PicoMQTT/blob/master/src/PicoMQTT/config.h#L23
