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.
# FEM CONFIG_MPSL_FEM=y CONFIG_BT_CTLR_TX_PWR_DYNAMIC_CONTROL=y CONFIG_MPSL_FEM_NRF21540_RX_GAIN_DB=0 CONFIG_MPSL_FEM_NRF21540_TX_GAIN_DB=20
Haha, very funny :

You said you have a Multi-NUS application that is working on nRF52840 and want to make it work on nRF21540 DK.
> For that I told you that the application remains same and you only need to change the configuration (board file and enable FEM). I asked you to enable FEM, since I thought that is the main motivation for you to move from nRF52840 DK -> nRF21540 DK.
The resent struggle you seem is to enable FEM and seems like you have trouble understanding the documentation link I attached to my reply.
In simple, select the right board files when creating the project and add this to proj.conf
# FEM CONFIG_MPSL_FEM=y CONFIG_BT_CTLR_TX_PWR_DYNAMIC_CONTROL=y CONFIG_MPSL_FEM_NRF21540_RX_GAIN_DB=0 CONFIG_MPSL_FEM_NRF21540_TX_GAIN_DB=0
FEM should then be enabled pn the nRF21540 DK with TX_GAIN set to 20.
Hopefully you feel that we are on the same planet after this :D
