Hi,
I'm working on a new PCBA design and it will require firmware update over the air of a STM32H563.
The ST67W will be used in access point mode at all times.
Is it possible to use the ST67W to update a target MCU? Is it done using the built-in bootloader? Is UART or SPI used for it? Can I also update the ST67W's firmware over the air as well?
I'm in the PCBA design phase and I want to ensure that all of the required data lines are connected properly, as well as the BOOT0 pin.
Any example would be helpful as well.
Thanks,
Étienne Machabée

Hi emachabeeinnotag,
FOTA update for both the ST67 and the host is possible. Refer to the STM32U575 example on GitHub and the project description on wiki for more details.

Hi Tarik,
the example only mentions the ST67 connecting to an AP. Is there a limitation preventing it from being used in AP mode?
I want to know this before ordering the 2 test boards and start trying it on my side.
The device will be used in a remote location with no access to the internet. The device will be in hotspot/AP mode, on which a PC will be used to upload the firmware on it.
Thanks,
