nRF5 SDK with nRF21540 DK

[Tatsuteke]

Hello,

I am currently trying to add a FEM (nRF21540) to an already existing BLE project that is using nRF5 SDK. For that purpose I ordered the nRF21540 DK that is using the nRF52840.

I tried using GPIOs to control the module but I understood that there is a specific timing for RX/TX switching. I also saw that there is support for that module in nRF Connect SDK but it would involve to modify nearly everything in the existing project to migrate it. Setting the FEM in RX mode only works but I will not be able to get the full usage of the module this way.

Is there a way for me to use a driver that could handle RX/TX switching in nRF5 SDK for example?

Note : I am using Segger Embedded studio with nRF5 SDK 17.1.0.

Thanks a lot in advance.

Sorry, there is no plans to implement support for the nRF21540 in the nRF5 SDK, in general you may find this informative:
