Dear Sir/Madam,
I am trying to enable FEM support on zigbee/light bulb, and want to SKY66112-11 FEM working on Receive bypass mode. I set all pins at proper setting at initialzation state but I found all pins always at low level state and I can't change them.
dts:
nrf_radio_fem: fem_skyworks_node { compatible = "skyworks,sky66112-11", "generic-fem-two-ctrl-pins";
ctx-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH>; ctx-settle-time-us = <1>; crx-gpios = <&gpio0 9 GPIO_ACTIVE_HIGH>; crx-settle-time-us = <1>; csd-gpios = <&gpio0 9 GPIO_ACTIVE_HIGH>; /* crx and csd connect together */ cps-gpios = <&gpio0 10 GPIO_ACTIVE_HIGH>; ant-sel-gpios = <&gpio1 7 GPIO_ACTIVE_HIGH>;
rx-gain-db = <11>; tx-gain-db = <22>; };
&radio { status = "okay"; fem = <&nrf_radio_fem>;};
