Thank you All, @Rahul & @Gaurav I am now intended to move the coreMQTT to my Tiva platform, ideally together with FreeRTOS-Plus-TCP stack, but don’t know where to start. I have a simple Ethernet based freeRTOS application running which use TI lwip stack, is it possible to interface coreMQTT with it? I see lots of dependency files from this demo, try to figure out minimal required file will be a big job, also, if possible, probably better to use FreeRTOS\_Plus\_TCP stack? which i might need some help to use this instead of Ti lwip. Any suggestions will be quite helpful please. Regards! Ping ---

Great. Maybe the configuration of the broker was not set right. Could you please follow the instructions [here](https://www.freertos.org/Documentation/03-Libraries/03-FreeRTOS-core/02-coreMQTT/02-Demos/01-coreMQTT-demo#option-2-using-a-locally-hosted-mosquitto-mqtt-message-broker-host-machine) for running the plaintext demo using a locally hosted broker. In brief, you can make a new configuration file, `myconfig.conf` as follows: ```auto listener 1883 allow_anonymous true ``` and run the local mosquitto broker locally using this custom config as follows: `mosquitto -v -c ` Let us know if there are any issues even after this. ---

Hi, DakshitBabbar Tried and it works, thank you, and it seems more repeatable. I am going to get familiar with this and will need to move it to Tiva embedded platform. Regards! Ping ---

> [@Ping](#): > > I have a simple Ethernet based freeRTOS application running which use TI lwip stack, is it possible to interface coreMQTT with it? Yes, you can use coreMQTT with LWIP. You’ll need to write a [transport interface](https://github.com/FreeRTOS/coreMQTT/blob/main/source/interface/transport_interface.h) implementation for LWIP. ---

Hello, Gaurav Thanks for reply, I looked at the link and also the demo file, cannot find the recv/send function body, only see the porotype defines. am I missing something ? Don’t think I know where to start. Another question, is it possible that I can import the project to another location, so I know which files are included in the solution, also avoid to modify original files by accident. Regards!

Found the function body Plaintext\_FreeRTOS\_send/recv, it is in transport\_plaintext.c, i guess I need to modify it for lwip, which I am not sure which one is. Ping ---

> [@Ping](#): > > I need to modify it for lwip Yes, that is correct. You need to write one for LWIP. As LWIP supports sockets API, you can refer to the following transport implementation - [aws-iot-device-sdk-embedded-C/platform/posix/transport/src/plaintext\_posix.c at main · aws/aws-iot-device-sdk-embedded-C · GitHub](https://github.com/aws/aws-iot-device-sdk-embedded-C/blob/main/platform/posix/transport/src/plaintext_posix.c).
