For a project we have to update the firmware of the STM32F469xx over the air by a Bluetooth connection
with a transmitter (can that be a smart phone?) and receiver on the microcontroller device part.
In an article I have read about such a possibility where an Android phone was used to perform the update
to the microcontroller.
I like to know several things:
1. Can I adapt the bootloader code of this microcontroller to support application firmware update via bluetooth.
Which steps do I have to perform to achieve this? Are there any guidelines for this?
2. In what way can I secure this firmware update over the air via bluetooth?
Any help I will appreciate!
Thanks in advance
