Hello Regunath

MQTT is not supported as of now for TM4C129x device family.

We have SUCCESSFULLY implemented MQTT pub/sub on TM4C1294XL launch pad. We have done this by porting the MQTT Client code available from Eclipse Paho.

We have achieved this by modifying the transport layer (transport.c) file and few more changes in application code. We basically made transport bridge between MQTT lib code to TI-RTOS socket.
Also, we need to create a new TI-RTOS task and run this MQTT app inside this task.

With this modification, we could successfully establish socket communication, MQTT publish and MQTT subscribe. We could maintain the subscribe connection (subscribed topic) always and getting the published topic data from MQTT broker any time.

Hi Regunath,
I'm also trying to implement MQTT on TI-RTOS. I'm using Concerto (M3 core).
So could you please provide source code you was ported?
Regards,
Tu
