TI-15.4-STACK-GATEWAY-LINUX-SDK: Sending Data from TI 15.4-Stack to a Custom Cloud Platform (Not AWS/IBM)

Part Number: TI-15.4-STACK-GATEWAY-LINUX-SDK

Tool/software:

Hello!

I've successfully set up the TI 15.4-Stack Linux Gateway Sample Project, and I’m currently able to send temperature data to a local gateway (192.168.XX.XX:XXXX) using the host_collector application on my Raspberry Pi 4 Model B.

However, my goal is to send this data to a custom cloud server using the MQTT protocol.

I've looked into the TIDEP0084 Sub-1 GHz Sensor to Cloud Industrial IoT Gateway Reference Design for Linux Systems, but I'm not sure how to adapt it for my specific application.

Additionally, the MQTT credentials I have for connecting to the HiveMQ cloud server include:

  • Cluster URL
  • Port
  • Username
  • Password
  • MQTT Topic
  • Database Name

Here are my questions:

  1. How can I configure the Linux Gateway example to forward data to a custom cloud server using MQTT?
  2. Where can I find the file that contains the sensor data being sent to the Linux Gateway? I need to access this data so that I can extract it and forward it to the cloud server.

Any advice or guidance would be greatly appreciated!

    Hi Timothy,

    I'm afraid this is outside of my area of expertise. You could try posting on Raspberry Pi forum?

    I'll close the thread but if any community members has a suggestion they can still post it.

    Cheers,

    Marie H

    Hi Timothy,

    1. That is more of a general software question. You could have a look at different MQTT libraries for your preferred programming language. For instance, paho-mqtt for Python.

    2. In prebuilt, in appclient.js, you can find received data in there: appC_processDeviceDataRxIndMsg

    Regards,

    Hello, Arthur!

    I was able to successfully send the data by integrating an MQTT function directly into the appClient.js file.

    I have a few more questions related to my ongoing project:

    1. If I want to add more external sensors and include their data (e.g., SGP30, SPS30, SEN0377) in addition to the built-in sensors on the LPSTK-CC1352R, which files should I modify within the sensor and coprocessor example project? Note: I already have a functioning I2C code using the i2ctmp example (found under TI Drivers).
    2. On the gateway side, are there any files I need to modify besides the appClient.js for my project?

    Thank you very much!
