Operating RF's registers on the nRF5430 network core

[sunny_axus]

Dear Nordic teams,

we need to develop a wireless audio product with .

Is it possible to develop our 2.4G wireless private protocol by operating registers on the nRF5430 network core?（Not using ESB interface functions);

Thanks.

Hi Yin, 

You would have to use ESB as en example and try an make your own. So that is what you can start looking at that. Gazell and ESB is what we have, so that will have to be what can reference in this case.

Hi Jonathan,

Thanks you later, I will try to do it.

Other question, Can I mixed our RF protocol with the LE audio protocol in same audio project?

Thanks

This is not tested by us so we are not sure that it will work flawlessly. You can try and mix but there might be issues with the timing from the two. Best way might might be to use timeslot from MPSL to involve ESB and ISO running concurrently.

Hi Jonathan,

Thank you.

1,Could you tell me which version of the LED audo SDK has the source code and has been mass-produced?

2, There is the error when compiling the network.however, compiling the cpuapp is okay.

C:/ncs/v2.5.2/modules/hal/cmsis/CMSIS/Core/Include/core_cm33.h:129:8: error: #error "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)"
129 | #error "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)"

ninja: build stopped: subcommand failed.

Could you tell me what's the issue?

Note, there is  a command for compile.

（C:\ncs\v2.5.2\nrf\applications\nrf5340_audio>west build -b nrf5340_audio_dk_nrf5340_cpunet --pristine -- -DCONFIG_AUDIO_DEV=2 -DCONF_FILE="prj_release.conf"）
