OM27462CDKP Development board PN7462 How to use USB & UART(HIF) at the Same Time?

[EE_Ark]

Hi, I'm using 'OM27462CDKP Development board' 'PN7462'. I need to use USB interface and HSUART(Only RX and TX pins without flow control). I'll connect a ble module to UART.

After I review examples in "PN7462AU FW and SW Examples Full Version - v06.10.00", i saw "phExDoorAccess" uses UART and defines "#define NXPBUILD__PHHAL_HIF" in "APP_NxpBuild" header file.

In my project I already use USB interface for communication with PC and i defined "#define NXPBUILD__PHHAL_USB" in "APP_NxpBuild" header file.

If I define both "NXPBUILD__PHHAL_USB" and "NXPBUILD__PHHAL_HIF" in my project's "APP_NxpBuild" header file compiler gives an error "HIF and USB can not be combined."

Can I use UART(without flow control) and USB interface at the same time? If I can what changes do I need to make in the PN7462AU FW API?

Thanks in advance.

Hello,

I have a technical question.

Can we deactive the usb in the embedded software and activate the uart and use it(2 pin ATX_A, ATX_B).

Waiting for your early reply.

Unfortunately, UART and USB interface can't use at the same time.

Have a nice day.
