Suggestion regarding FOTA with stm32f405 and gsm module.

[Manny]

Hello,

I wanted to know some suggestion regarding a project, and adding FOTA support in it.

The project is stm32f405 based and it configures the gsm module as a server and one can make request and get response using https request.

I wanted to update the firmware of the stm32f405 using the gsm module, I have looked into muc like the STM32WB series that have FOTA implemented for Bluetooth, and some basic principle used by the implementation. But I wanted to use the existing stm32f4 mcu and don't want to port my project to stm32wb.

Any suggestion(hardware or sotfware) on how can I implement the FOTA.

Thankyou.

On the STM32 side look at the IAP (In App Programming)​ example. Look also at support for using HTTP/GET or FTP as a means of pulling data from servers.

Thank you, I will look into it.

What are your though of OpenBLT. Should I use OpenBLT as a starting point and modify it to work with the gsm module or should I use the IAP driver as starting point?
