Hi,
We wanted to connect our device to Azure, we have downloaded Azure SDK and checked the examples. I did not see any example for the OTA (over the air) firmware upgrade for CC3220SF device, I request you to share the example for OTA with Azure using MQTT. Let me know any OTA agent support for the azure is available.
If sharing of the example is not possible let me know the procedure to perform it over MQTT (any document). I was searching for the information online but could not get any information on what topics the device must subscribe and publish the request for firmware download.
We are expecting the firmware to receive in chunks and store.
Operating System: FreeRTOS
Device: CC3220SF
Cloud: Azure
I got one link in Azure site and it has some node.js example, but it is of no use to me, this only talks most from the cloud side implementation. node.js example I checked but not much detailed information on topics and procedure.
https://docs.microsoft.com/en-us/azure/iot-hub/tutorial-firmware-update
I request you to help me in this regard, let me know where can I get detailed information on the device side OTA firmware upgrade.
Thanks,
Harish
Hi Harish,
We do not have a demo that shows the entire OTA process using Azure. The OTA bundle would have to be loaded from the Azure cloud to the CC32xx device. There is a MQTT demo in the Azure plugin that demonstrates how to connect to the IoT hub, or you can also load a file using HTTP.
Then you can write the bundle to the file system and run the update using the OTA examples in the SDK as a reference. Take a look at the Cloud OTA example from the CC32xx SDK and the OTA application note.
Best regards,
Sarah
