Hello,

You can read more about the FEM support in the MPSL documentation here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/mpsl/doc/fem.html. It should be straight forward to enable FEM support in any of the BLE examples.

Relevant configuration settings:

### FEM configration
CONFIG_MPSL=y
CONFIG_MPSL_FEM=y
CONFIG_MPSL_FEM_SIMPLE_GPIO=y

and DTS overlay:

/ {
    nrf_radio_fem: pa_lna {
        compatible = "skyworks,sky66112-11", "generic-fem-two-ctrl-pins";
        ctx-gpios = <&gpio0 28 GPIO_ACTIVE_HIGH>;
        crx-gpios = <&gpio0 29 GPIO_ACTIVE_HIGH>;
    };
};
