IWR6843: Integrating MQTT with cellular modem and IWR6843

Part Number: IWR6843

Hi Team,

We are trying to explore the possibility of establishing MQTT connection using a cellular modem and IWR6843. As we know, IWR6843 has Cortex R4. The demo codes which we are using currently, use TI RTOS. Although UARTs available on IWR6843, are being used for sending commands and data. We are going to use one of the UART (after hardcoding the chirp profile configuration) for interacting with a modem from Quectel. 

My query is regarding availability of any MQTT library for TI RTOS with above explained setup. is it available? If not, how can we go about it? 

note: I am not sure if the above question is fit for this forum, I just asked because of the Hardware IWR6843 we have chosen for our application.

Regards,

Kamlesh

    Hi,

    So I am not very familiar with MQTT, so take this with a grain of salt since it is primarily based on what I have read on MQTT with a few searches. My understanding is that MQTT is primarily intended for wireless IoT applications, and relies on a loseless communication protocol. Based on that premise, I would imagine for such a usecase you would connect to some sort of wireless MCU for something like bluetooth, wifi, or similar to achieve both of these items. In that case, the wireless MCU would likely be converting the data from the radar device to MQTT, and I imagine some of our wireless connectivity devices may already be familiar with how to do this. Let me know if I am understanding correctly, and if you have any additional feedback or questions for us. This is a new request for us so I'm interested in how to get this resolved.

    Best Regards,
    Alec

    Hi Alec,

    Thank you for the response. You are right in the sense that TI has some wireless chips which can facilitate this. However, We want to run the MQTT application on IWR6843 itself. IWR6843 will have a free UART which can be utilized to send AT commands to a cellular modem like Quectel cellular Modems. This requires, as I understand, an MQTT library for TI RTOS, along with any TCP IP/LwIP stack implementation for TI RTOS. Please point me to any resources if available.

    Hi Kamlesh,

    I am not familiar with such a library for TIRTOS. You may be able to do some searching online as well as on these forums and find something that is usable, but I have not personally seen such a library before. If you find anything, please share it here so others may be able to leverage it going forward as well. 

    Best Regards,
    Alec
