case about nRF Cloud does ota for stm32 through nRF9160

[peter.min]

Hi,

1. ota to nRF9160 via nRF Cloud is ok.

2. Is it possible to upgrade the new firmware of stm32 through nRF CLoud with the help of nRF9160?

3. If this idea works, please provide similar examples or blogs for reference.

Thank you for all your assistance.
Kind regards,

Hello, 

You should be able to download a new image from any server using our nRF9160: Download client sample. How you update the STM32 is not known to me. 

Kind regards,
Øyvind

Hi Øyvind,

1. I would like to know whether the nRF Cloud UI  supports upgrading third-party MCUS, and whether there are trigger button or not?

Had to reach out to our nRF Cloud team on this. The simple answer is: Yes it is possible, but the cloud/UI/FW doesn't explicitly support it (for third party devices).

There was a another customer asking a similar question on how to update their nRF52 device using the nRF91, please see  nRF91 and nRF52 FOTA using the nRF Cloud 

 To answer your question:

They can create an APP FOTA update and provide whatever update file they want. On the device: if they are using MQTT, they won't be able to use the nrf_cloud library FOTA, they would have to write their own FOTA handling.

REST FOTA would be more straightforward to implement.

Kind regards,

Hi Øyvind,

1. Thank you for your reply

2. Through checking online documents, I found that nRF Cloud does not support third-party firmware and chip upgrades for the time being, only nRF9160 and nRF5 series chip upgrades.

Thank you for all your assistance.
Kind regards,
