IoT Technology: Get Connected with SimpleLink Sub-1 GHz Sensor to Cloud solution


This TI Design provides a reference for creating an industrial IoT gateway that is capable of connecting a network of wireless sensors to an enterprise cloud provider. In this reference design, a long-range, low-power wireless network, made up of Sub-1 GHz CC1310 or CC1350 devices (both are supported) that run the TI 15.4-Stack-based application, is connected to the AWS IoT cloud. In addition, an online dashboard is provided that allows the user to visualize the real-time sensor data as well as send actuation commands from anywhere in the world using an Internet-connected device with a web browser.


Main Features

  • Large network to cloud connectivity enabling long range, up to 1 km line of sight (LOS)
  • IEEE 802.15.4e/g standards based Sub-1 GHz solution with the TI 15.4-stack SDK
  • Based on proven hardware designs enabling quick time to market with out-of-the-box ready to use demonstration software
  • TI Processor SDK for Linux provides scalability across multiple Sitara processors such as AM437x and AM57x



Sitara AM335x device on the BeagleBone Black

The connection between the wireless sensor network and the cloud is made possible by TI’s Sitara AM335x device on the BeagleBone Black development platform. On one side, the AM335x is connected to a Sub-1 GHz device acting as the central node in the wireless network, and on the other side, the device is connected to the AWS IoT cloud using Ethernet. These two connections allow the AM335x device to act as a gateway to get the sensor messages from the wireless network to the cloud and, also, to get the actuation requests from the cloud dashboard sent back to the wireless network.


Due to the long-range and low-power capabilities of the Sub-1 GHz sensors, this TI Design is useful for any type of application that would benefit from distributed sensing. This reference design provides a blueprint that gives the ability to visualize or actuate tens or hundreds of sensors while only needing one gateway device, TI’s Sitara AM335x, to be connected to the Internet.



This reference design provides a list of required hardware, schematics, and foundational software to quickly begin your Internet of things (IoT) product development. Amazon Web Services (AWS) IoT service, which is brokered by stackArmor, was chosen as the cloud service provider for the demonstration. The software design, however, is architected to be flexible to enable other cloud service providers.



This TI Design enables IoT in numerous applications, such as building security gateways, door and window sensor networks, asset management and tracking, and other IoT-enabled home and industrial automation applications.

Comment List
  • I procured  two of these kits and was able to successfully run the default application.Now I want to customize the application/create my own application that runs on the gateway to push data from sensors to SAP Cloud platform.I am not getting any information on how i can update the application that runs on gateway.A USB to serial cable comes with the kit but I am not sure where which pins will it fit to since there is no documentation around it.Please can anybody guide.

  • No problem Kas!


    I should have added that this was using the normal data rate of 50kbps, there is an even lower data rate of just 5kbps that promises longer range so I should think you'd definitely be ok using this underwater.



  • ,


    Thank you very much, I appreciate all the effort you have gone to for me. From what you are measuring that's some serious attenuation but what's nice is even at -100 dBm you are still getting a solid signal. And with the frequency at 868 MHz this looks like a possible solution for short underwater hops.



  • Hi Kas, the device has now been in the water!


    I hooked up the CC1350 Sensor board from the IoT kit with a sensors booster back and some breadboard to get 3xAA battery power into the device, wrapped it in two layers of self seal bags, then put it inside a clear plastic box, weighted it all down with a brick, and plunged it into some seriously cold water outside!


    It was at a depth of about 60cm, though the tank itself is only about that diameter so I reckon there was only about 30cm of water all around. On top of that, though, is the distance back to the base station of BeagleBone and the other CC1350 board, which is easily 10m, and back inside as well, so there was a fair degree of attenuation there too.


    The screenshot below shows we got an RSSI of -100dBm from in the water, when I pulled it back out again that went up to about -76dBm. This is on the EU 868MHz frequency, but I don't really expect that will make a difference.




    I'll add more details into my RoadTest report, and I'll give some more thought to how we could collect you some better data too. I guess taking the system out on a road trip to a marina or harbour would be the next step, what sort of depth are you looking for in your application?



  • A meter would be a great start, my only question is what type of out of water linking is there. By this I mean how much of the signal is going through the water and how much is going water->air->Water. I really appreciate you looking into this for me.



  • Hi Kas, the next step for me is to battery power this, so I'll then seal it up in a box and give it a try underwater!


    What sort of depth were you looking for? I could probably manage a metre relatively easily.



  • Congrats to the winners, I'm looking forward to their reviews. Would be interested in possible underwater usage of these radios or from above to underwater and what range you get in each case..
