Sub 1GHz Low Cost Mesh Network

Other Parts Discussed in Thread: CC1101, MSP430G2533

Hi there,

Texas very new (October 2014)Sub-1GHz Low Cost Mesh Network wireless connectivity. I would like make demo project with CC1101 and MSP430G2533 chip. In user guide, there are PC control window GUI, which communicate via RS232 with processor. Where i can find this GUI. Another question, in GUI screen sample i can see node data (example node 02, data 22222222). How i can change this data. I understand, that same software for every hardware, only number changed, master 1 and slave nodes 2,3, etc. , but i need to send data and receive from slave nodes to master and master to slave nodes. How this data exchange is intended to do. Where i can find variables or something.

Thank you

perry

    hi, perry,

    The GUI is not a necessity, it is just used to interpret the data from UART for better demo effect.

    This reference design is supposed to be used in most IoT application. Sensor data from slave node is desired. Periodically data reports initiated by slave and on-demand data request initiated by master are available.

    Data from slave node is defined in the library, node 0x02 with the data 22222222, node 0x03 with the data 33333333, ..., node 0x0F with the data 0F0F0F0F. node with the id large than 0x0F will report with data 11111111. Modify node id in config.h before download program into hardware will get different demo data.

    hi, Fan Zhang62

    Thank you for answer, i am grateful. I understand GUI, that it is not necessity. "Periodically data reports initiated by slave and on-demand data request initiated by master", i also understand. "Data from slave node is defined in the library", means, that you can not change slave node data in run time, because it is constant and hide in library. What i want to do, is just change slave node data dynamically. I am interesting to make demo working, but after demo, i want to do something myself, where data can change dynamically between master and slave. Why only demo, if people can not do anything with it, after they get demo work. I like this new Low Cost Sub 1GHz Mesh Network, after i read guide. Network have self configuration and not need repeaters for long range, because nodes also work as repeater and if some node stop work, network do new configuration automatically.

    Thank you answers forward

    Hi, Perry,

    I am glad that you are interested in the solution.

    We are considering to modify the library to offer more API, such as dynamically changing data, to customers.

    hi,Fan Zhang,
    Texas very new (October 2014)Sub-1GHz Low Cost Mesh Network wireless connectivity.I undestand GUI introduce above,but i can not found a tools to repace it.In order to interpreting the data from UART for better demo effect,could you send the GUI to me?

    Thanks a lot!
