Hi @p123 ,

the UART protocol was chosen particularly because the Virtual COM port is readily available on the integrated ST-Link of all demo boards and no additional HW is necessary.

It is expected that each user of the SBSFU example will eventually replace it with whatever protocol is most suited for the user application. SPI or I2C were used by different customers in the past without problem.
