How to send UModulation siganl by HCI cmd

Hi,

   If there is any SDK example can support to control KW45 Bluetooth board to send unmodulation signal by HCI cmd? If not, How can we change the code and support it?

   Our surrounding: 

    IDE version: MCUXpresso IDE v11.8.0_1165

    SDK version: KW45B41Z83 V2.12.7

    FW: HCI_black_box

    hope your support, thanks.

Hi， @Annie_he 

As my understanding, the modulation and demodulation is implemented by physical layer, not by HCI layer.

HCI layer is only a middle layer to transfer commands from host to controller and transfer events from controller to host, or transfer data from both side. It means, for HCI layer, there is no relationship with modulation or demodulation. 

Can you please let me know why do you need this kind of HCI cmd to send UModulation siganl? Or provide me more details about your using cases?

Best regards,

Christine.
