Non-blocking solution?

[Ryanauger95]

Is there any plan to support a non-blocking api in the future? For most applications, it is important to be able to publish and subscribe at the same time.

Hi PiedPieper,

We do support non-blocking mode using ./configure --enable-nonblock or #define WOLFMQTT_NONBLOCK. This prevents any call from blocking and will return with MQTT_CODE_CONTINUE. This mode only works correctly in a single thread or if you manage the context between two threads yourself. With non-blocking mode you could accomplish your requirement.

I believe the feature you are requesting is multiple-thread support, which is at the top of our feature list to add.

Thanks,
