nRF21540 implementation on a nRF52840 without OS

[Dominik Eugster]

Hi

I'm looking for an example implementaion code on the nRF52840 without an operating system. Is there some example or application note?

I connected the SPI and all IO Pins. I have no Zephyr code.

I'm working with the nRF5 SDK

Aha. When you said you did not want to use Zephyr OS, I though that meant you did not use the nRF Connect SDK either.
Either way, that is not what you ask.

Many of our BLE samples in the nRF Connect SDK have Front End Module support, such as the Bluetooth: Peripheral UART.
And I guess the Working with RF front-end modules will be useful.

Is this what you were looking for?

yes, this is usefull, I think I will start with this.
I added the files manually to my propject and will call  the functions according to the docu. There are a lot of options and functions which are not needed and this is the reason why I asked for an example which is for adding the nRF21540 to an existing BLE project. The reason is that all is working, but the range of the BLE signal is too low. I added the nRF21540 and have to add the software layer to control the nRF21540, this is what I have to do.

Here the files I added to my project

Hi

Normally for working with the nRF21540 in the nRF Connect SDK, Kconfig handles most of the includes, libraries and drivers.
Therefore, if someone wanted to add nRF21540 functionality to their project, it should be as simple as building for a different board.
I would recommend them to have make a custom board using inspiration from the nrf21540dk_nrf52840 to include the nRF21540 into their BLE application, in addition to the documentation I have already provided to you.

While this likely is not the same as your workflow, it might be able to help you some.

Sorry to bother you again, but this is exactly what I am looking for:

But to be honest I don't know how to use the Kconfig. I will fread the docus maybe I missed some basic informations
