Hi,

There are no plans to provide FEM support in opensource implementation.

Humm thanks Marjeris.

Although my confusion between MPSL and SL, we can see that the mentioned PR 64 that updated the radio driver to v1.9, removed the fem/simple_gpio folder that was added on v1.6.1. Later, the PR 73 has mentioned the introduction to MPSL FEM support on radio driver and also introduced a mpsl_fem_protocol_api.h header under SL opensource folder, but still without control functions (the ones to change LNA/PA pins, delay, etc). Is there intention to continue development there and to bring back simple gpio FEM support to open source?

Best,

Rodrigo

Hi,

There is no FEM support for vanilla zephyr. The PR you are refering to is for 802.15.4 radio driver, which introduces open source 802.15.4 SL, not opensource MPSL. The opensource 802.15.4 SL is very basic and lacks almost all features from close source 802.14.4 SL.

Best regards,

Marjeris
