[lwip-users] Callbacks in MQTT

We are trying to use the MQTT application present in LWIP along with a local Mosquitto broker. As per the documentation, the connect callback is supposed to be called after the connection goes through. We are not able to replicate the same when we utilise the detailed description provided here -  lwIP: MQTT client (nongnu.org). The client gets connected, but the callback is not entered. The conclusion that the callback is not entered is based on the flags we have added at the start and end of the callback. Is there any parameter change/ change in the order of calling which needs to be done?

Eagerly awaiting your response
