Multi-NUS on the nRF21540-DK

[SteveHx]

I have succeeded in running the Multi-NUS package on the nRF52840DK. My client's client learned of the nRF21540EK and wants to try using it to extend the range in the present application. Is there an equivalent of the Multi-NUS package available for this board? Fallback would be an NUS application whereby i could gather the routines to access the control lines for the 21540 and merge it with the Multi-NUS software.

The Kconfig file shows exactly the items you described. I remain skeptical that the application code need not change when adding features like the PA and the LNA, but I'll run with it until I can prove otherwise. What I need right now is a way to make it compile. The error messages do not lead me to any corrections I need to make. Help?!?

Okay, for my next trick I need to connect the RF of the nRF21540DK to the SMA on the nRF21540EK. I cannot find any documentation as to the connector type used on the DK, and it's smaller than even the very tiny RF connectors I have on hand. Why wasn't the connecting cable included with the Development Bundle, and what connector type or cable type do I need to procure?
