regarding HCI UART over CDC/ACM.

[Weili]

Dear Expert,
can I use Bluetooth: HCI low power UART(nrf SDK with nrf52840 dk board ) and then remapping UART to CDC/ACM?

Hello,

It will be when you use the DK because the UART pins are routed to the on-board Jlink that serves as UART - USB bridge to your PC. Another alternative is to use the HCI USB sample and connect the PC via the nRF USB port here:

Hi sir,

thanks for you reply,

I have tried HCI USB,but it emulated Bluetooth devices not a CDC/ACM

our customer wants replace TI CC2541 usb dongle,because cc2541 too old,

So we wants HCI over CDC/ACM mode,

Can nrf52840 do HCI over CDC/ACM mode?

Hi,

I don't see any reasons for why this should not work, but it will require some modifications to the sample application. Have you tried this already? The USB CDC ACM Sample Application demonstrates how you can enable the CDC ACM class in an application.
