Open thread example for Node device configuration

[Rohit Rajapure]

Hello Everyone,

We are developing one custom device using open thread protocol.

We are using SDK - nRF5_SDK_for_Thread_and_Zigbee_v3.0.0_d310e71 and Dev-kit - nRF52840.

We have one custom Host device (which is based on STM) to communicate with the Host device through UART, we are developing a Master (or Node nRF52840) device (using Open thread).

And we have our Gateway which used Open thread protocol to send commands to Node device.

Here, the entire system working is as below.

1. Host and Node communication happens using UART. 

2. Node and Gateway communication happens using Open thread protocol.

So, I am new to this open thread protocol, I am studying now for this project. In the meantime, I would like to know which example from Thread (SDK) can configure as Node(nRF52840) to accept Command from the Gateway system. And send received command to Host(STM) via UART.

Please share the example to study for my requirement and its working architecture. Or we need to build from scratch please share steps to configure as a Node system.

Thanks in adavance

Hi Rohit

If you're just starting out with a Thread project, I would suggest going for SDK v4.1.0 if there's nothing holding you to v3.0.0.

Do you want an example that communicates over UART and transmits the received data from UART over Thread to a Gateway, is that right? If so, I would suggest checking out the Thread CLI example for instance which demonstrates a small OpenThread application that enables the user interaction through the command line interface for instance. The Thread part of this application I assume would be similar in your node, while the CLI would have to be replaced by however you would like using the UART peripheral.

For documentation to get started with OpenThread I would suggest the online resources available in our Infocenter for starters.

Best regards,

Simon

Hi Simon,

Thank you so much for the feedback,

- My Gateway device and Node device communicate using Openthread protocol. The gateway sends some commands to Node via thread.

- And Node device and Host device (STM MCU) communicate using UART.

- Node receives the commands from Gateway device via Thread, those commands were further sent to the Host (STM MCU) by Node device using UART.

- I will go through the links shared by you.

Thanks and Regards
