Re: [lwip-users] MQTT not working on lwip-2.0.2. Callback has an issue.

Hello Eric ,

Have updated what you have suggested in the code.

Here is my output log :

Initialized the lwip.

Lwip IF is up now!

Into MQTT create connection

MQTT client created successfully.

Connection to broker initiated

MQTT Connection disconnected 256

Answering your question on why I want to use LwIP on my local system:

I am using the LwIP library on a TI processor. Facing a callback issue there as well, but that is after the system has connected to the broker. 

I thought of getting the same setup running on my local system so I can understand the flow easily and debug the embedded code using this as the reference.

I only have one question:

When exactly is the mqtt_ connection_ callback () called ? It does return the status as MQTT_ CONNECT_ DISCONNECTED , but at what point in the code is it called?

When a connection has been initiated.. or ?

Regards,

Chandana
