Why does the RCP example not have USB transport in the nRF5 SDk for Thread v4.1?

Why does the RCP example not have USB transport in the nRF5 SDk for Thread v4.1? It only has SPI and UART.

Hello,

 

Why does the RCP example not have USB transport in the nRF5 SDk for Thread v4.1?

 Do you mean the ncp\radio example?

It looks like it only supports spi and uart, yes. But I believe all the building blocks are there to do USB, as it is included in the ncp\ftd.

Any particular reason why you can't use the ftd variant?

BR,

I mean the ncp/radio example.

Are you referring to the "NCP" example when you say the "FTD variant"? 

I don't want to use NCP architecture since wpantund is deprecated. Instead I would like to use the OpenThread Daemon with RCP architecture. My interpretation is that the "radio" example is RCP. Is this correct or incorrect?

According to the ncp example's description, the examples\thread\ncp\radio example is used "to communicate with Userspace WPAN Network Daemon (wpantund) on Uniz-like operating systems."

The ncp\radio example doesn't come with a USB backend in our SDK, so if you need this, you need to implement it. To test it with USB, you may be able to use a DK with it's UART -> USB converter in the programmer, but I am not sure whether that will work on your hardware. You need to test.
