Thank you Andreas - with the latest NCS releases, do we now have the ability to port out the FEM control signals?

Hi,

There is no support for this with nRF5340 yet. You can try using MPSL radio notifications but it does not expose any information about what happens inside the timeslot, so I do not see any easy way of doing this. Hooking onto radio events with PPI is not going to help either due to the state transition time of NRF21540.

Best regards,

Andreas
