How to Update stm32wb firmware over LTE module?

Hello,

I intend to develop an application using the STM32WB and a Telit LTE module (TX62). I would like to know if there is a way for me to use the LTE module to update the firmware of the STM32WB remotely. Can this be done via UART communication between the two? Would I need to develop a bootloader for the STM32?

Thank you.

You'd have to facilitate.

You can perhaps have the Telit modem download (FTP, HTTP ?) and stage the update in it's own file system.

Your STM32WB could query and validate, and then initiate a method to pull the data and write the firmware image. Figure you'd need to commit a couple of KB of flash for a boot loader to action this. Your primary app could do the file pull via the modem.

    Pity you couldn't have brought your discussion back here rather than continue to off-topic the older thread.
