NCS v1.5.1 PA LNA support for bluetooth

[leox]

NCS Release v1.5.1 now supports PA LNA, couldn't see any BLE examples on how to configure and use PA/LNA. could you provide any instruction/guidelines on how to enable/use the PA/LNA with NCS v1.5.1 please?

• Added Radio front-end module (FEM) support for Bluetooth LE in single protocol configuration and multiprotocol configuration with Thread

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>;

    };

};
