Hello Sergio,

I recommend using the QBlue ISP Studio for flashing the QN902x over UART. Implementing your own code for flashing the QN902x over SPI would be time consuming. However, you can follow the description of the ISP protocol in the chapter 4.4 ISP Protocol Description of the QN9020 Software Developer’s Guide.

Regards,
