CCS/CC3220SF: Programming Over WiFi _ CC3220SF

Part Number: CC3220SF

Tool/software: Code Composer Studio

Hi,

As I checked there is your suggested two programming Method of CC3220SF; First method is programming over CDN Servers (Github, Dropbox) with OTA functions, Other method is proggraming over UART with UART Bootloader commands. But, Our target is to add programming capability to CC3220SF over Wifi from Local Area Servers (Our PC at Local Area). At our project, there is no any access to remote internet. So, we need to programme our Chips over Local WiFi Network. So, is it possible to boot Chip over Wifi with our Bootloader application which we will develop? If is it possible, could you direct me about it?

Thanks for your support.

    Hi,

    As first step you need to upload your application with capability to obtain new image wirelessly. This can be done via UART ROM bootloader or by Gang programming (programming SPI flash chip by 3rd party flash programmer). Your application can be designed to obtain OTA image from your local server (by http, by your own protocol, etc.). At your case you will be able re-use OTA examples. You will need to change change CDN layer to communication with your local server.

    Hi Kamal,

    The local OTA example uses the CC3220 as HTTP server which gets the OTA image from a local network client.

    I believe this is the demo you are looking for.

    The same is demonstrated by the out of the box (OOB) example.

    Hi,

    Could you direct me with reference document? In OTA IOT programming API document, there is "Local Link support" page. So you mean this area? If not, could you give me any other reference document or detailed information?

    Thanks.

    It is not a document but an example application within the SDK.

    The example folder includes README file with description and instructions.
