Hi,
Two month ago I have test nRF21540 and nRF54L15, they cannot word with each other.
However, I notice these days updated with
https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/device_guides/fem/index.html
I have tried again but it still cannot work
My config is
#FEM general
CONFIG_MPSL_FEM=y
CONFIG_MPSL=y
CONFIG_MPSL_FEM_NRF21540_GPIO=y
CONFIG_BT_CTLR_TX_PWR_DYNAMIC_CONTROL=y
CONFIG_MPSL_FEM_NRF21540_TX_GAIN_DB=20
CONFIG_MPSL_FEM_NRF21540_RX_GAIN_DB=13
CONFIG_MPSL_FEM_NRF21540_RUNTIME_PA_GAIN_CONTROL=y
CONFIG_BT_CTLR_TX_PWR_ANTENNA=20
# CONFIG_BT_CTLR_TX_PWR_PLUS_8=y
My overlay is:
/ {
nrf_radio_fem: name_of_fem_node {
compatible = "nordic,nrf21540-fem";
tx-en-gpios = <&gpio0 0 GPIO_ACTIVE_HIGH>;
rx-en-gpios = <&gpio0 1 GPIO_ACTIVE_HIGH>;
pdn-gpios = <&gpio0 2 GPIO_ACTIVE_HIGH>;
mode-gpios = <&gpio0 3 GPIO_ACTIVE_HIGH>;
};
}; //54L15
