Bluetooth firmware update

Question asked by Max Veen on Jul 18, 2017

Hi all,

 

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

 

Max
