Hi,
I have a custom designed PCB and firmware using the QN9090. The only interface for programming during manufacturing is SWD and once inside a case can't be accessed. No UART available only a LCD display and single button. Is there a source code example of the types of operations required for FCC, such as transmitting on a certain channel. I believe there is a binary that can be used for FCC validation with the DK6 board but since my GPIO is very different and I don't have a UART available this won't work. I need to utilize the LCD and button to setup the various testing modes.
Thanks.
