QN9090 based consumer product FCC testing

alexedge — Wed, 18 May 2022 15:48:44 GMT

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.

Hi Alex,

Hope you are doing well. We have the QN9090 RF System Evaluation Report for BLE Applications (QN9090x_Certi_Tools.bi), but it needs a serial interface, I think this is the example you mentioned.

This example provides RF evaluation test results of the QN9090 for BLE applications (2FSK modulation).

You can download the MCUXpresso project from the QN9090 page:

Hope this helps.

Regards,

Ricardo
