Other Parts Discussed in Thread: CC1350

Dear Ti,

Now i am working for read temperature value at farm, i am using cc3220 custom designed board for upload temperature value to the website.

now i want to add multi nodes(clients) for read temperature from various locations. the every nodes have a minimum 100 to 500 meter distance.

My need:

1. i want to assign mess network for collect data from every clients, and every clients are act as a master, which device is best for long range with mess network support?

2. here i will connect with internet to only one node that is only possible at the farm, but if i upload program through OTA how to update the nodes with out internet?

3.If there is any possible to internet connected module is download the program from my dropbox and upload to the clients through any other wireless way to long range?

 

My concept:

Main board is connected with internet and there is multi nodes are connect with main board like a mess network, main board is collect temperature with labels  from all  long range(100-500 meters) nodes. then the data's are upload to the website with labels. 

main board is connect with internet so the device is reprogrammed through OTA easily. but other clients are can't. and also i can't done with Local OTA. if there is any option for internet sharing for long range or upload the program via main board(connected with internet) to clients.

    Hi Natesh,

    I'm a little confused by the mixture of your requirements. You mention both long range connection back to a main node that is connected to the internet and a requirement for mesh. 

    • Do you really need a 1-hop range of 100-500 meters in a mesh network configuration or just to achieve a range of 100-500 meters back to the main internet-connected node?
    • If you need the former, can you describe why?

    How often do you need the nodes to be updated?

    The CC32xx devices do not support mesh and probably won't be ideal in such a long range solution. I recommend you start by taking a look at our Sensor to Cloud solution here:

    Dear

    sorry If i confused you, now i explain my need,
    my friend have a mushroom farm in india, there is maintain exact temperature for mushroom farming. so he ask help to me for solve the issue.
    there is have wifi connection so he tell to upload the temperature to server for remote monitoring, i was complete that with CC3220, but now he increase the farm shed to ten numbers the every shed have minimum 100 to around 700 meters distance.

    Current Scenario of location:
    1. Must read temperature value in every sheds, and these values are upload to server for remote monitoring is also must.
    2. There is only one Wifi connection so i can connect only one CC3220 or other MC with internet for upload the temperature value to the internet.
    3. i want OTA in every nodes for upload new firmware.

    My questions:
    1. Which MC is best for my Concept?
    2. How to upload new firmware to all nodes(There is only one MC is connect with internet)?
    3. How to read temperature data from all nodes ( Nodes have 100 to 700 meters distance)?

    you said Sub1 GHZ is support long range transmission, it's use to collect temperature data from all nodes so i desired master is cc3220, and other nodes are CC1350, but here i have a doubt upload OTA to cc3220 is easy because that is connect with internet, but how to upload the new sketch to my CC1350.

    If you have any suggestion or idea to my concept, please let me know,
    thank you

    with regards

    Hi Kannannatesh,

    Yes, I believe a solution similar to the Sensor to Cloud design that I have linked will suit your application. You will have to implement the OTA from the gateway device to the edge nodes, but it will be possible since the new firmware can first be downloaded to the CC3220. The design should demonstrate well how to read the temperature data from the nodes.
